Herbs/Botanical plants are considered as God's gift to human beings in the form of natural medicines, like the one well known "Sanjeevani booti" described in Hindu Mythology. The traditional and ethno-veterinary practices have been in use for centuries, transferring the knowledge from generation to generation and they are accessible, easy to prepare and administer, with little or no cost at all. Even though the modern developments in therapeutic field brought about a rapid decline in traditional medicine, the plant-based remedies are still having a crucial role as potential source of therapeutic aids in health systems all over the world for both humans and animals. Among the 21,000 medicinal plants listed by the World Health Organization (WHO), 2500 species are native to India, which stands first in the production of medicinal herbs. This innumerable treasure of medicinal herbs brings India the distinction of 'the botanical garden of the world'. Nowadays immune-based therapies are gaining more importance than monovalent approaches which are having limited benefits. Apart from the actions like treating diseases, control of ecto- and endo-parasites, fertility enhancement, bone setting and poor mothering management, an array of herbal medicines have been reported which are having immunomodulatory effects like modulation of cytokine secretion, histamine release, immunoglobulin secretion, class switching, cellular co-receptor expression, lymphocyte expression, phagocytosis and so on. The present article describes in brief few of these important ones viz., ashwagandha, amla, tulsi, arjuna, aloe vera, garlic, turmeric, ginger, shatavari, neem, guduchi, kiwifruit, tut, kamala, palashlata, kokilaksha etc. being used for human and animal health benefits.

In 21st century, world is facing the problem of population growth, increase in the incidences of the disease, unemployment and change in ethical values (Mahima et al., 2012a). Due to development of antibiotic resistance by the bacteria (Verma et al., 2007; Lambey et al., 2009; Kumar et al., 2011, 2012a, b) and antiviral resistance (Verma et al., 2012) by the viruses, the researchers are now thinking towards immunomodulation. The term immunomodulation is generally used to describe the pharmacological manipulation of the state of activity of the immune system. Immunomodulators either make an increase or decrease in the magnitude of immune response. The augmentation of immune response is known as immunostimulation/immunopotentiation while suppression of immune responsiveness is termed as immunosuppression (Chauhan, 2010). From a therapeutic point of view, immunomodulation refers to a process and a course of action in which an immune response is altered to a desired level (Archana et al., 2011). The development of science and biotechnology particularly in field of nutrition leads to the formation of designer milk (Mahima et al., 2012b) and designer eggs (Mahima et al., 2012c) that can also be used for enhancing the immunity (Mahima et al., 2012d). The uses of herbal plants as health promoters are gaining increasing attention in both consumer and scientific circle (Upadhayay et al., 2011; Hashemi and Davoodi, 2012). Various physiological products, microbial products, synthetic chemicals, cow therapy (panchgavya) (Verma, 2005) and herbal products have immunomodulation property. Among these, the herbs exhibit an array of diverse biological activity such as antistress, adaptogenic, anti-ageing and immunomodulatory activity. Many herbs are being used by veterinarians fruitfully to treat a variety of conditions of animals as well as in birds (Dhama et al., 2012). Herbs provide potent anti-inflammatory, antibacterial, antiviral and antifungal benefits. Improvements have been shown or reported with those suffering from flu, allergies, colds, rheumatoid arthritis, bacterial/viral infections, hepatitis, heart disease, asthma, skin infections, ageing, chemical intoxication etc. and effective in treating cancers (Mathew et al., 2010; Umashanker and Shruti, 2011). Apart from infectious and systemic diseases, topical botanical/herbal application is also effective for specific conditions like ear infections, wounds, burns and skin irritations (Mizaei-Aghsaghali, 2012).
Herbs, traditional/indigenous plants and ethnoveterinary medicines, having multiple beneficial advantages, have been used since long for strengthening of body and its immune system and to keep away or fight against diseases. 'Nakul Samhita', an Indian ancient literature, describes the treatment of animals with many herbs, written about 5000 B.C. Our Ayurveda system of medicine, an ancient medicinal system, is a good knowledge store for herbs and minerals having medicinal properties. Several medicinal plants used in Indian traditional medicine called Rasayanas which increases the resistance of the body against a variety of infections have attracted the attention of many scientists. It is one among the eight branches of Ayurveda which has been meant for nourishing and rejuvenating drugs with multiple applications for longevity, memory enhancement, immunomodulation and adaptogenic (Patwardhan and Gautam, 2005). Herbal therapy is also popularly called as "Rasayana Chikitsa". In our country the ancient medicinal system of Ayurveda is a vast repository of knowledge in herbals and minerals of medicinal properties. The rasayana drugs are endowed with multiple properties like delaying ageing, improving mental functions and preventing diseases (Sharma, 1983). Burgeoning interest in medicinal herbs has increased scientific scrutiny of their therapeutic potential and safety, thereby providing practitioners with data to help farmers make wise decision about their use (O'Hara et al., 1998).
Ethnoveterinary medicine deals with people's knowledge, skills, methods, practices and beliefs about the care of their animals and to keep them healthy, which are acquired through practical experience and has traditionally been passed down orally from generation to generation (Toyang et al., 2007). Since centuries before the introduction of western and allopathic medicines, all livestock keepers relied on these traditional practices. According to the World Health Organization, at the moment, at least 80% of people in developing countries depend largely on these practices for the control and treatment of various diseases. Limitations of synthetic drugs and chemicals in terms of higher cost, anticipated toxicity and adverse effects are becoming known to the people. On the other hand, the natural medicines are more suitable for animal and human health care with the advantages of low cost and total safety (Rahal and Kumar, 2009a). Some of them are studied scientifically by in vitro and in vivo studies but most of them are yet to be scientifically validated. In the era of emerging antibiotic resistance and residual effects in food products, food safety concern, these can play wonderful role for safeguarding health of humans and animals.
In the last few years there has been an exponential growth in the field of herbal medicine and these drugs are gaining popularity both in developing and developed countries because of their natural origin and less side effects. Many traditional medicines in use are derived from medicinal plants, minerals and organic matter. The World Health Organization (WHO) has listed 21,000 plants, which are used for medicinal purposes around the world. Among these 2500 species are in India, out of which 150 species are used commercially on a fairly large scale. India is the largest producer of medicinal herbs and is called as botanical garden of the world (Umashanker and Shruti, 2011). The country has one of the richest plants medical traditions in the world. There are estimated to be around 25,000 effective plant-based formulations, used in folk medicine and known to rural communities in India. There are over 1.5 million practitioners of traditional medicinal system using medicinal plants in preventive, promotional and curative applications. It is estimated that there are over 7800 medicinal drug-manufacturing units in India, which consume about 2000 tonnes of herbs annually (Verma and Singh, 2008).
In literature many plants have been listed having immunomodulatory effect and some of them have been proved by using modern scientific methodologies. In this paper, few important herbs are discussed with their immunomodulatory action/properties either on laboratory animals, domestic animals or human beings.
• Helpful in delaying the process of ageing.
Documented systems of medicinal herbs include Chinese medicine, Japanese Kampo, Tibetan herbs, Indian Ayurveda and African healing herbs. The promotive, preventive, corrective and curative approach in health care and the medicinal plants pocessing such properties are indeed the strength of the Indian Systems of Medicine (ISM). The ancient masters of Ayurveda and Siddha organized, codified and synthesized the medicinal wisdom with sophisticated theoretical foundation and philosophical explanations. They adopted the fundamental doctrines of Darshana philosophy, particularly the Nyaya, Sankhya and Vaiseshika, which encompassed all sciences-physical, chemical, biological and spiritual. Nevertheless, the holistic approach of ISM, more particularly of Ayurveda, which internalize all aspects of health and diseases, is perhaps the greatest contribution of Indian medicine (Pushpangadan, 2006). Indian medicinal plants provide a rich source for antioxidants that are known to prevent/delay different disease conditions. The medicinal plants also contain other beneficial compounds like ingredients for functional foods. Hence, the global knowledge about Ayurveda and Indian herbals are hopefully be enhanced by information on the evidence-base of these plants. This ultimately helps in yielding rich dividends (Vaidya and Devasagayam, 2007).
Modulation of immune response to alleviate diseases has long since been of interest. Herbal medicines have always been a form of therapy for livestock among resource poor smallholder farmers (Mizaei-Aghsaghali, 2012). Recently, there has been progress on the ethnomedicinal plants as immunomodulatory agents because of the fact that plant extracts have been widely investigated during last few decades in different parts of the world for their possible immunomodulatory properties. In due course, several studies have demonstrated the isolation of potential bioactive molecule and few have been tested as herbal formulations. Several plant extracts, compounds and formulations have also been patented.
Herbal medicines for infectious diseases: The use of herbs and botanical extracts for antimicrobial property and immune enhancement has been practiced from very old days in nearly every culture across the globe (Ahmad et al., 2006; Roxas and Jurenka, 2007). A number of plants, plant extracts and constituents have been identified as having anti-microbial, antiviral or antifungal activities and are often considered as immune enhancing (Rios and Recios, 2005). Spices such as onion, garlic, mustard, red chilli, turmeric, clove, cinnamon, saffron, curry leaf, fenugreek and ginger are some medicinal plants and dietary constituents having antimicrobial, immunestimulating and antioxidant property (Rajendhran et al., 1998; Tilak and Devasagayam, 2006).
Herbal medicines for non-infectious diseases and disorders: Herbal medicines have a complex mode of action on various organs and systems due to active ingredients present in them. They are supposed to have greater impact on different factors that promote growth and health, by improving physiological and immunological functions of body. Thus, they can be considered as more sustained and long term solutions. Special contribution of these products has been proved on microsomal system against liver dysfunctions and thereby is shown to be as efficient liver protectants. Interestingly, it has been found that Nelumbo lucifera Gaertn (Nymphaeaceae) is a well-known aquatic plant which has been used for the treatment of several disorders including skin disease, cough, inflammation, fever etc (Mukherjee et al., 2010).
Anti-cancer: Several herbal preparations are proved to boost up the immune system and make the body to defend against future or existing cancer. Some of the Indian herbs with anti-tumor property are echinacea, Aloe vera, tulsi, turmeric, satavar, garlic, aqueous extracts of black pepper and cardamom etc. Aromatherapy encompassing the use of essential oils derived from different types of plant materials or parts that are claimed to possess therapeutic properties is proven as an effective anticancer therapy (Boehm et al., 2012). Another unique anticancer herb is green tea or black tea which contains tumor growth inhibiting factors as well as other polyphenols, vitamin C, carotene, fluoride, zinc, selenium (Mahima et al., 2012e), manganese, potassium, niacin and folic acid. The black tea contains theaflavins, which inhibits the chymotrypsin-like activity of the proteasome and proliferation of human multiple myeloma cells (Mujtaba and Dou, 2012). Chinese medicine also reveals various anticancerous herbal preparations which are gaining attention nowadays (Efferth et al., 2007). Moreover, in Chinese medicine, the anti-cancer activity of a mushroom called Ling Zhi which contains triterpene as the active ingredient has been evaluated by researchers. The cytotoxicity exerted by triterpene is due to alteration of proteins involved in cell proliferation and or cell death, carcinogenesis, oxidative stress, calcium signaling and ER stress (Majdalawieh and Carr, 2010; Yue et al., 2010).
Immune enhancing activities: Several botanicals are found to have immune enhancing activity, demonstrated by especially Chinese workers from time to time. The immunostimulating activities of many of these components have been most widely studied in mouse, chicken and human cell lines. Emerging evidence indicates that herbal plants exert their beneficial effects on animal immune system mostly by plant secondary metabolites. For example, Coriolus versicolor extracts has unique potency for using as an adjuvant since it contains glucans containing (1,4) backbone with (1,3) and (1,6) glucocytic linkages (Ng, 1998). Ginseng with its steroidal saponine, has immune-stimulating properties including cytokine production (IL-2, IL-6, TNF-α and IFN-γ), macrophage activation and lymphocyte activity. Saponins have ability to stimulate the cell-mediated immune system, as well as to enhance the antibody production. Saponins reportedly induce the production of cytokines such as interleukins and interferons. Meyer saponins, Quillaja saponins and the butanol extract of Lonicera japonica and de-acetylated saponin-1 administered on the nasal mucosa all stimulate the immune response in vivo. Herbal plant polysaccharides, also has been extensively studied for immunomodulatory effects. The polysaccharides obtained from four Chinese herbs, Astragalus root, Isatis root, Achyranthes root and Chinese Yam, considerably improves the antibody titre in vaccinated chicken (Hashemi and Davoodi, 2012). Commercial preparations of immunomodulatory herbs is shown in Table 1.
Neem tree is known as the tree of the 21st century (United Nations Declaration). It is regarded as a highly exploited medicinal plant of Indian origin, with its every part (namely root, bark, wood, twig, leaf, flower, fruit, seed, kernel and oil) having medicinal use. Neem plant extract stimulates phagocytic activity and antigen presenting ability of macrophages. It stimulates cytokines and thereby the immune system (Thatte and Dhanukar, 1997). It enhances mitogenic response of spleenocytes to concanavalin-A (Con-A). It stimulates production of IL-1, IFNγ and TNF-α reflecting activation of Th1 type of response. Also enhances antibody titres against Newcastle's disease antigen in broiler chickens (Renu et al., 2003). It is an effective antiseptic for the treatment of small pox. Aqueous extract of neem possess anti-complement activity. The plant extracts are effective against allergic disorders and limiting anaphylactic reactions. Feeding of neem leaves increases immunity in immunosuppressed condition like IBD; antiviral activity against duck plague virus in poultry (Xu et al., 2012) and increase the survival rate in Asian seabass Lates calcarifer fingerlings against Vibrio harveyi infection (Talpur and Ikhwanuddin, 2013). It prevents leukocyte apoptosis mediated by cisplatin and 5-fluorouracil in mice. Neem oil selectively activates the cell mediated immune response by activating macrophages and lymphocytes. As a bioinsecticide, neem has been reported effective in the control of 400 insect species, including flies, spiders and nematodes. It enhances DTH in psoriasis patients and has anti-leprotic action (Chauhan, 2010).
Guduchi means to rejuvenate dead cells. It is widely used in veterinary folk medicine and has also been claimed to be beneficial according to 'Ayurveda' for the cure of jaundice, skin diseases, diabetes, anemia, emaciations and various infections for its anti-spasmodic, anti-inflammatory, anti-arthritic and anti-allergic properties (Chopra, 1982). It has immunopotentiating activities and is anti-bacterial, anti-allergic, anti-diabetic, analgesic and diuretic. It stimulates reticuloendothelial system, bone marrow cellularity and proliferation of stem cells and enhances the haemopoietic growth factor and IL-3. It enhances GSH and Vitamin C and so function as an effective antioxidant (Prince et al., 2004). The aqueous extract of this plant is capable of increasing leukocyte count in mice and it is also proven to have hepato-protective effect (Ganguly and Prasad, 2011). This plant extracts showed anti-neoplastic activity in cultured HeLa cells. The Cordifolioside A and syringing present in the plant extract have immunomodulatory activity (Sharma et al., 2012). It has anti-complementary activity and is a potent hepatoprotectant so effective in preventing hepatotoxicity. Immunomodulatory proteins in its stem increase the number of macrophages and its phagocytic activity (Rege et al., 1999; Aranha et al., 2012). It has been shown that mice pre-treated with G1-4A exhibited protection against mortality due to lipopolysaccharide (Desai et al., 2007). It is also helpful in prevention of cyclophosphamide induced immunosuppression in mice. It has synergistic effect with cyclophosphamide in reducing animal tumours. Also, the alcoholic extract of Tinospora cordifolia has shown to activate tumor associated macrophages and showed antitumor effect on the spontaneous T-cell lymphoma and may have some clinical implications (Singh et al., 2004). It is being used as an immunostimulant in HIV patients and also has action against avian influenza viruses. Inhibition of ochratoxin A induced suppression of chemotactic activity and production of IL-1 and TNF-α by mouse macrophages has been reported. Polyclonal B cell mitogen (G1-4A) found in its stem extract enhanced immune response in mice. By the activation of macrophages, it increases the granulocyte-macrophage colony-stimulating factor (GM-CSF), leading to leukocytosis and improved neutrophil function. It is having effect on classical complement pathway by inhibiting C3-convertase (Thatte et al., 1994). Immunosuppression due to cholestasis (obstructive jaundice) can be overcome by the use Giloy (Thatte and Dahanukar, 1989).
Astragalus membranaceus root has a long tradition in Chinese medicine. It is generally considered to have immunomodulatory, anti-inflammatory and adaptogenic (stress-relieving) properties. Research shows that Astragalus root stimulates the immune system in many ways. It increases the number of stem cells in bone marrow and lymph tissue and encourages their development into active immune cells.
It also enhances the body's production of immunoglobulin and stimulates macrophages and can activate T-cells and Natural Killer (NK) cells Astragalus stimulated NK-cell activity of human peripheral blood lymphocytes and restored steroid-inhibited NK-cell activity (Mills and Bone, 2000). Its traditional and modern usage is primarily for immune-related complaints (frequent infections) or malignancies. Astragalus extracts and constituents have been shown to enhance the activity of NK cells and lymphocyte activated killing of tumors, as well as stimulate the activity of other immune cells such as macrophages and B-cells. Much of the research on this herb is published in Chinese and its usage is most often combined with several other herbal preparations making specific dosing recommendations difficult. Astagalus is generally considered safe with few reported adverse events (Cho and Leung, 2007).
Ashwagandha is a potent adaptogen or vitalizer, with immunomodulatory (Kushwaha et al., 2012), antitumour and cytoprotective properties (Mishra et al,, 2000). It possess both immunostimulatory and immunosuppressive properties. It prevents myelosuppression induced by cyclophosphamide, azathioprin and prednisolone. It has the property of mobilization and activation of macrophages (phagocytosis), increases activity of lysosomal enzymes and antistress activity in mice and rat. These pharmacological activities are attributed to the presence of several alkaloids and withanolides. Extracts of Ashwagandha has antioxidant (Blecha, 2001) and detoxifying properties and reduces tumor incidence in mice and increases serum T3 and T4 in mice. Anti-carcinogenic effects in animal and cell cultures are due t o decreasing the expression of nuclear factor-kappa B, suppressing intercellular tumor necrosis factor and potentiating apoptotic signalling in cancerous cell lines. It has been shown to be immunoprotective against Bordetella pertussis infection in animals and possess better efficacy in inhibiting growth of breast and colon cancer cell lines in compare to doxorubicin. It induces inhibition of delayed hypersensitivities. Aswagandha has been proven to prevent stress induced changes in adrenal function and enhance protein synthesis. Milk fortified with it increases total proteins and body weight. Bharavi et al. (2010) has proven that Withania somnifera root powder can prevent Cadmium-induced oxidative stress in chicken.
Amla is well known for its anti-oxidant and detoxification properties along with tonifying and antiaging effect (Saini et al., 2008). As an adaptogen, amla improves immunity and augments both cell mediated and humoral response. It enhances IL-2 and gamma-IFN production and inhibits apoptosis. It enhances NK cell activity and Antibody Dependent Cellular Cytotoxicity (ADCC). It acts as an immunomodulator in repeated respiratory infections in human beings. Amla possess anti-inflammatory and antipyretic properties. It is a potent immunosuppressant as that of dexamethasone and can be used in arthritis (Ganju et al., 2003). It helps to reduce inflammation and oedema (Baliga and Dsouza, 2011). As a tonic, it is prescribed for rejuvenation, recuperation and vitality. It inhibits immunosuppressive effects of Chromium on lymphocyte proliferation. A high amount of Ascorbic acid is present in the fruits of amla. It is useful for anaemia, jaundice and dyspepsia in combination with iron (Sai Ram et al., 2002). It can also be used to treat and prevent cancer (Baliga and Dsouza, 2011).
Tulsi is regarded as the "Queen of plants"/"The mother medicine of nature". It is an analgesic, anticancer, adaptogen or antistress agent and also having antidiabetic property (Hussain et al., 2001; Rahal and Kumar, 2009b). Its anti-oxidative property and inhibition of lipid peroxidation are due to the presence of eugenol (Gupta et al., 2002). Immunostimulant potential of Tulsi is helpful in treatment of immunosuppression. It shows its immunomodulatory effect by increase in IFN-Y, IL-4, T helper cells, NK cells (Mondal et al., 2011) thus reducing total bacterial count, increasing neutrophil and lymphocyte count and enhancing phagocytic activity and phagocytic index. Oil from Tulsi seed can mediate GABAergic pathways and by this it can modulate both humoral and cell-mediated immunity (Mediratta et al., 2002). Aqueous extract showed immunotherapeutic potential in bovine sub-clinical mastitis. It inhibits mast cell degranulation and histamine release in presence of allergen. It is useful in constipation and wounds. Tulsi plant has shown to enhance the production of RBC, WBC and haemoglobin in rats. It is more potent than dexamethasone in the treatment of acute viral encephalitis. Tulsi is suggested to shorten the course of illness, clinical symptoms in patients suffering from viral hepatitis and also enhances survival of viral encephalitis patients. It is also useful in allergic and inflammatory disorders due to the action of its oil and has shown to decrease significantly the symptoms of arthritis and edema (Reghunandan et al., 1995; Singh et al., 2010). It has been proven as a herbal adaptogen in reversing the Cadmium-induced oxidative stress in chicken (Bharavi et al., 2010).
It has immunomodulatory and anti-inflammatory activities by suppressing the proinflammatory cytokines. It can also act as a bio-enhancer and anti-tumor agent (Patwardhan and Gautam, 2005). Its alkaloid piperine has a variety of pharmacological activities like nerve depressant, antagonistic effect on electroshock and chemo-shock seizures as well as muscular incoordination. Piperine increases bone marrow cellularity in mice and rats. It helps in prevention and control of Giardiasis in human beings. The root and fruit decoction are used in acute and chronic bronchitis and cough.
It is used for wound/fracture healing with immunopotentiation. The extract from stem bark of this plant has the property of inhibition of HIV-protease. It is used in fracture and wound treatment of animals for its immunopotentiation properties. It is a cardiac tonic herbal medicine for man. It is an antineoplastic agent due to the cancer cell growth inhibitory constituents residing in its bark, stem and leaves(gallic acid, ethyl gallate and the flavone luteolin) (Pettit et al., 1996).
It promotes wound healing by stimulating macrophage and fibroblast activity. The active principle 'Acemannan' induces apoptosis in cancer cells, stimulate leukocyte and lymphocyte and cause the release of IL-1, IL-6 and TNF-α. It can modulate immune response by augmenting secondary humoral immunity in rats (Halder et al., 2012). Mucilaginous leaf-gel (Acemannan) has anti-inflammatory property. It prevents ultraviolet induced suppression of DTH by reducing keratinocyte derived immuno-suppressive cytokines. It can selectively stimulates cytokines and activates lymphocytes (Egger et al., 1996). Its isolates have shown to exert inhibitory properties against Staphylococcal infections (Lorenzetti et al., 1964) and Candidiasis (Stuart et al., 1997). It also shows some beneficial effect in antiretroviral therapy (Awodele et al., 2012).
It is having antiseptic property which was first demonstrated by Louis Pasteur (Tyler, 1994). Allyl sulfides are known for antitumor, anticarcinogenic and antistress action. Organosulfur compounds of garlic-inhibit growth of tumors in animals and modulate activity of diverse chemical carcinogens. It increases NK cells production and activation and helps in maintaining homeostasis of immune function. Garlic is having effect on multiple cytokines like reduction of proinflammatory cytokines (IL1, IL6, IL8 and TNF) and stimulation of IL10 (Spelman et al., 2006). It enhances production of IL-2, augment macrophage (oxidative burst) and T lymphocyte (blastogenesis) functions. Due to its ability to influence multiple proinflammatory cytokines, it is having hypoglycaemic action and protection against inflammatory bowel disease (Ebadi, 2002). Garlic is useful in food poisoning, tympany, sterility, FMD, skin infection, contact hypersensitivity, stomach-ache, arthritis, internal parasites and rheumatism. Garlic boosts IL-10 and IL-4 and is useful in treating psoriasis (O'Hara et al., 1998). It possess antioxidant property also (Tilak et al., 2005). Researchers are focusing on an extract of A. sativum called ajoene, which appears to protect CD+ cells from attack by HIV early in the viral life cycle. At low concentrations, the drug appears to have little toxicity and its anti-HIV activity is 45 times more powerful than the drug dextran sulfate. Ajoene is found only in fresh A. sativum and is not readily procurable. Recent investigations reveal that A. sativum impairs the activity of the liver enzymes that process protease inhibitors and raises the protease inhibitor levels. The in vitro antiviral activity of A. sativum extract (GE) on human cytomegalovirus (HCMV) has also been evaluated in tissue cultures, plaque reduction and early antigen assay. A dose-dependent inhibitory effect of GE is evident when GE was applied simultaneously with HCMV (Guo et al., 1993). Allicin can protect against plasmodium infection by enhancing the host's innate as well as adaptive immunity (Feng et al., 2012).
It is used as a general tonic, immunostimulant and blood purifier. It possesses anti-inflammatory activity and antioxidant activity (Devasagayam et al., 2001). Curcumin inhibits growth of ovarian cancer cells and induce apoptosis in lung cancer cell lines. Anti-cancer effects are also observed in various cancer cell types including skin, colon, duodenal and ovary in the laboratory animals. Anti-cancer properties of curcumin may be mediated, at least in part by inhibition of inducible form of NO synthase. It increase intestinal IgA in animals fed a high fat diet. It is useful in mouth blisters, sprains, internal parasites, skin disease, constipation, internal injury, eye diseases, wounds, galactagogue, external parasites, sprains, mastitis, cough, cold, bone fracture, heatstroke, wounds, FMD, haematuria, broken horn and stomach-ache. Anti-inflammatory effect gives relief from rheumatoid arthritis and osteoarthritis. It is also an anti-Alzheimer's agent. It also acts as HIV-1 and HIV-2 protease inhibitor, hepatoprotective, hypoglycemic and hypolipidemic agent (Jain et al., 2007; Goyal et al., 2010).
Ginger which is called "The Great Medicament" in Ayurveda, is effective against a variety of ailments. It is useful in constipation, food poisoning, diarrhoea, eye diseases and haematuria. It is also useful in conditions like indigestion, tympany, dysentery, stomach-ache and skin diseases. The most effective principle in exerting antimicrobial activity is citral, along with Curcumene, a sesquiterpene, which is found to inhibit Rhizoctonia solani (Agrawal et al., 2001). The ethanol extract of ginger is also bactericidal, especially against gram positive bacteria (Alzoreky and Nakahara, 2003). It also has antioxidant and anti-inflammatory property (Chang et al., 2012; Park et al., 2012).
Ginseng has been in use for centuries in reducing stress and boosting energy and it has been shown to stimulate every aspect of the immune system in vertebrates (Bensky and Gamble, 1993). It is used to regenerate liver cells after toxicity or injury, even in cases of chronic disease. It is being used as anti-stress factors for very long years in human and animal medicines with proven results (Blecha, 2001). The saponins from its root stimulate lymphocytes and cytokines (Cho et al., 2002) and those cytokines include IL-1, IL-12, TNFα and INFγ (Song et al., 2002). It is used as a restorative tonic and known as an adaptogen. Panax enhances NK cell activity and increase immune cell phagocytosis. It has protective role in cancer and also possess anti-inflammatory activity. Ginseng is often used to treat feline leukemia and secondary conditions in animals arising from cancer, such as rapid weight loss cachexia and blood infections. It improves endocrine and liver function in dogs (Kwon et al., 2003) and in horses increases antibody response against Equine herpesvirus 1 when given for a few weeks prior to being vaccinated (Pearson et al., 2007).
It has anti-inflammatory properties and contains high content of vitamins which helps in healing and enhances immunity. High content of Tannin is present in its leaves. It modifies the expression of Th1-and Th-2 cytokines. It up-regulates CD4+, CD8+ and CD19+ cell population and increases splenic T and B cellular proliferation. It has shown analgesic, anti-inflammatory and significant anti-tumor property against human hepatoma cells. It is also having anti-cancer property (Sun et al., 2012).
It has anti-inflammatory action and stimulates macrophage cytokine production and Natural Killer (NK) cells. It can stimulates neutrophil and B-lymphocyte activity. Liquid preparations have been shown to have immune-stimulating property (Uluisik and Keskin, 2012) and enhance several white blood cell types as well as phagocytes (Burton Goldberg Group, 1999). It enhances production of specific IgG in mice. It is well known among humans as a first line of defense against the common cold and flu (Blumenthal, 2004). Extracts of Echinacea enhance phagocytosis and protect the gut from harmful microorganisms. The herb may inhibit the growth of some tumors. It is very effective in treating canine seasonal and chronic upper respiratory infections, including kennel cough (Reichling et al., 2003). The juice from the aerial portion of E. purpurea and aqueous and alcohol extracts of the roots have viral inhibition properties in cell culture (Wacker and Hilbig, 1978).
It has anti-carcinogenic, anti-inflammatory and antioxidant property. Immunostimulatory action has been shown by murine peritoneal macrophages in vitro and boosting immune system of humans (Naeini et al., 2009). It is useful in diarrhoea, stomach-ache, dysentery, FMD and paraplegia (Cherng et al., 2008).
The water-extractable and the alkali-extractable polysaccharides from Solanum nigrum have been proven to possess potent antitumour activity (Li et al., 2009) which may be associated with their potent immunostimulating effect (Ding et al., 2012). It causes significant increase in IFN-α, IL-2 and IFN-γ production and decrease in IL-10 expression. Its antitumor activity is reflected in activation of different immune responses in mice rather than by directly attacking cancer cells (Li et al., 2009).
Ethanolic extract of A. calamus rhizome is having immunosuppressant action which inhibited proliferation of mitogen (phytohaemagglutinin) and antigen (purified protein derivative) stimulated human Peripheral Blood Mononuclear Cells (PBMCs). It also inhibited production of Nitric Oxide (NO), interleukin-2 (IL-2) and tumor necrosis factor-α (Mehrotra et al., 2003). It inhibits the production of proinflammatory cytokines, posses anti-inflammatory activity and has applicability against IgE mediated disorder. It has anti-obesity property, inhibits adipogenesis in 3T3-L1 cells and reduces lipid accumulation in fat cells. It is also effective against cattle ticks. Belska et al. (2010) demonstrated that the pectic polysaccharide from A. calamus L. in low concentrations was able to stimulate in vitro IL-12 and nitric oxide production by murine macrophages (Belska et al., 2010).
Anti-inflammatory action of plant is exhibited by eugenol due to the suppression of the nuclear factor-κB pathway. It is also found that eugenol in noncytotoxic concentrations exert immunomodulatory/anti-inflammatory action on cytokine production by murine macrophages (Bachiega et al., 2012). In a study by Halder et al. (2011) it was found that clove oil can modulate the immune response by augmenting humoral immunity and decreasing cell mediated immunity (Halder et al., 2011).

Herbal and traditional botanical products ideally have multiple effects and are helpful in a variety of disease conditions, for beneficial effects on human health as well as their companion/domestic animals. When considering on a global basis, the use of plant products as immunostimulants has a traditional history not only in India but also in almost all ancient civilizations including Chinese, Arab and American. These are good alternatives to conventional chemotherapy. Same immunomodulatory herbs at a glance are shown in Fig. 1.
As India is having a rich biodiversity of herbs and medicinal plants, efforts should be made in their identification and testing/validation for their immunomodulatory properties and to prepare prophylactic and therapeutic formulations for safeguarding animal health and production, as well as for human health. Research and development (R and D) programs should be encouraged for their scientific validation. By quality control approach, adulterations of these precious preparations with pesticide, heavy metal residues or other drugs could be avoided. Integrated and holistic monitoring of biological process is necessary to achieve clinical success (Multiple immunomodulating approaches). Historical knowledge from the great traditions like Ayurveda and others will have an important role in bioprospecting-drug discovery utilizing traditional knowledge of herbs, medicinal plants and indigenously well known drugs being used since ancient times. Integration of modern medicine, traditional knowledge and use of science and technologies with a systems biology approach can be most suitable in this regard. Herbal and traditional/indigenous preparations need to be popularized for their wide application and acceptance, for which promotional approaches need attention so that their full potential can be utilized for safeguarding health and production in livestock, pet and domestic animals, poultry and laboratory animals apart from numerous human health benefits.

Effective Work Habits»
Effectiveness of a Multicultural Team
by Mary Bauer
The differing perspectives of multicultural team members help in problem solving.
1 About Creative Tension in the Workplace
2 The Importance of Diversity in Communications
3 Why Is Effective Communication Important in Management?
4 Discussion Topics for Team Communication
Putting people of different cultures together on a team is like handing a set of watercolors to a sketch artist who has always worked with charcoal. At first, the artist may feel awkward, but the new medium opens a whole new range of possibilities and boosts his creativity. Multicultural teams often experience similar unease with the unfamiliarity of other ethnic groups and they may take a little longer to get to know and understand each other, but the end result is well worth the extra time. Differing views bring richness and creativity to decision making and problem solving.
Cultural differences in communication can impact a team's performance. People from a European background, for example, tend to speak directly and value frank conversation. By contrast, individuals who trace their roots to Asia or Latin America tend to be more indirect and to hide their emotions. It may be difficult for a team member of European origin to recognize when an Asian counterpart is unhappy or has identified a problem, and a Latino may find it difficult to deal with the brutal honesty that Americans of European descent highly value. On the other hand, people who prefer indirect communication treat others with respect and rarely will cause tension on the team.
Perception of Time
Americans of European descent value time and perceive punctuality as a sign of respect and reliability. Other cultures, however, have a very different concept of time. Africans, for example, do not embrace the linear concept of time. Their focus is on relationships and events. An activity takes whatever time is required. Deadlines are not a part of this concept. Similarly, Latinos view relationships as paramount and will not shortchange communication at an ongoing meeting to be on time for the next meeting. They perceive this as disrespectful. Thus, time expectations may present a challenge to a multicultural team. Cultural awareness and communication help to overcome these obstacles.
A Multi-faceted View of Issues
Due to their diverse cultural backgrounds, multicultural team members view problems from different perspectives. This provides the team with a broader toolkit for problem-solving. Diverse team members also bring a deeper understanding of their culture, which may enhance the company's ability to market to different ethnic audiences. They also may bring useful language skills to the table.
Management's Role
Due to differing cultural perceptions and values, management must set clear expectations to ensure the team's effectiveness. For example, to address diverse concepts of time, managers must articulate deliverables and deadlines. At the same time, managers must allow extra time for team members to learn about each other and develop a bond. Acknowledging differences is the best way to deal with them, so managers should not sidestep diversity, but rather highlight the value they place on it. Finally, managers must closely monitor the team's performance and intervene if necessary in the event of tension or inappropriate behavior.

Il est le fils du fondateur de la hammawiyya, le cheikh Hamallah.

Il a lui-même plusieurs fils : Chérif Ahmed Sidi Haïdara (fils aîné), Moulaye Oumar Haïdara et Messeoud Haïdara. Ce dernier est président de la tariqa « Hammawiya Tidjaniya » du Mali.

Rôle politique
Bouyé est le seul leader religieux malien à avoir publiquement appelé à voter en faveur du futur président Ibrahim Boubacar Keïta lors de l'élection présidentielle de 2013. Il prend toutefois ses distances avec ce dernier dès l'année suivante, avant de rompre franchement vers 2017. À l'élection présidentielle de 2018, il finira par appeler à voter au premier tour pour Alou Boubacar Diallo, et au second tour pour Soumaïla Cissé.

Fish Oil Helps Prevent Weight and Muscle Loss in Cancer Patients
Roxanne Nelson
March 1, 2011 — Supplementation with fish oil might help prevent muscle wasting and weight loss in cancer patients undergoing chemotherapy.
In a small study of 40 patients newly diagnosed with nonsmall-cell lung cancer (NSCLC), those who received fish oil supplements maintained weight, muscle mass, and muscle quality.
The study, published online February 28 in Cancer, found that about 69% of the patients who took fish oil gained or maintained muscle mass. In comparison, only 29% of patients in the control group maintained muscle mass; as a group, they lost an average of 1 kg of muscle.
"Fish oil may prevent loss of weight and muscle by interfering with some of the pathways that are altered in advanced cancer," said senior author Vera C. Mazurak, PhD, assistant professor in the Department of Agricultural, Food & Nutritional Science at the University of Alberta in Edmonton, Canada.
"This holds great promise because currently there is no effective treatment for cancer-related malnutrition," she said in a statement.
Dr. Mazurak pointed out that fish oil is safe and nontoxic with virtually no adverse effects, and might benefit patients with other types of cancer or chronic diseases that are associated with malnutrition. It might also be beneficial to elderly individuals who are at risk for muscle loss.
However, in their paper, the authors point out that previous results with fish oils in cancer patients have been mixed. Three large phase 3 trials failed to demonstrate a clear benefit of eicosapentaenoic acid (EPA) on either body weight or lean tissue in cancer patients. But other studies have been positive, and have shown that supplementation with more than 2 g/day of EPA could stabilize weight loss, attenuate lean tissue wasting, and increase survival in patients with advanced cancer.
There have also been numerous studies that reported other health benefits associated with fish oil supplementation. One study, for example, found that fish oil supplementation was associated with a lower risk for breast cancer in postmenopausal women. There is also extensive evidence that fish oils might prevent and treat many aspects of cardiovascular disease.
Weight and Muscle Maintained
In the current study, Dr. Mazurak and colleagues hypothesized that EPA derived from fish oil might help patients maintain or gain muscle. They randomized the 40 newly diagnosed NSCLC patients to receive either EPA 2.2 g/day (n = 16) or standard care (no intervention; n = 24) while undergoing first-line chemotherapy.
The skeletal muscle and adipose tissue of the participants were measured using computed tomography images, and weight was recorded at baseline and throughout chemotherapy. The average time on the study was 10 weeks, and was comparable between the 2 cohorts.
The authors designed the current trial as an open-label study to "avoid the challenges of previous studies," such as contamination between treatment groups and poor compliance.
Patients who received standard care lost an average of 2.3 km, whereas patients who received fish oil were able to maintain their weight. Less than a third of the control group maintained or gained weight while undergoing chemotherapy (range, 0.0 to 4.6 kg), whereas more than two thirds of the fish oil group maintained or gained weight (range, 0.0 to 6.7 kg).
Patients with the greatest increase in plasma EPA concentration after supplementation had the greatest gains in muscle (r2 = 0.55; P = .01). In the control group, there was evidence of loss of skeletal mass, with some patients losing up to 5.2 kg of muscle from baseline to the end of treatment.
Overall treatment response was similar between the 2 groups. Overall, 69% of the fish oil group (n = 11) had stable disease or achieved a partial response after chemotherapy, compared with 67% of the control group (n = 16).
The fish oil was well tolerated, and no serious adverse events were reported.
"The use of fish oil as a therapy to prevent body composition changes in patient populations who are at an increased risk of developing cancer cachexia merits further investigation," the authors conclude.
The study was funded by a Canadian Institute of Health Research Grant and by a Queen Elizabeth II Graduate scholarship.

You don't need animal protein to build muscle. You just need protein – it can come from a plant-based source.
Agreed, we all need protein to grow and survive but this does not mean that we have to kill an animal to get our daily dose of muscle-building protein.
Most non-vegans argue that veganism is not proactive if one wants to build muscle mass and boost fitness so let's first get this out of the way… you don't need animal protein to build muscle. You just need protein – it can come from a plant-based source or an animal source.
Experts usually recommend getting 0.5 to 0.7 grams of protein for each pound of your body weight. Use this as a guide but don't get all obsessive over it and measure each protein source you consume. Ideally, you need to consume at least one protein-rich source with every meal.
But here's the deal; almost everything contains protein and there is absolutely no way you can be at a protein deficit, even if you are vegan.
Meat is a complete protein source but you can mix and match several vegan protein sources and thus, create a complete protein meal. Therefore, vegans often have a lot of a variety in their diet as opposed to carnivores.
Start exploring plant proteins. Fortunately, there are several vegetarian protein sources to choose from so you can never get bored. Moreover, most plant-based proteins are adaptable so you can have them in any way you like.
You can begin by stocking on various soy proteins, such as tofu, tempeh, soy burgers, soy milk and roasted soynuts. Nuts and seeds are often packed with protein so make sure you have them for snacks instead of that bag of chips. Beans and peas are not only rich in protein, but they are abundant in calcium too.
Perhaps the best time to pack on some protein is after exercise or a weightlifting session. Studies show that those who consume protein or protein shakes post-workout experience greater body (muscle) mass, strength and calcium levels. Protein after a workout can also prevent fatigue. Soy protein powder with frozen fruit or nuts and seeds and soy milk is an excellent idea for a post workout beverage. You can boost your diet with multi-vitamins containing iron, calcium, magnesium, zinc and vitamins B12 and D.
Oils don't have protein but nuts and seeds do. So instead of using canola oil, peanut oil or coconut oil for your salads and soups, sprinkle some whole nuts and seeds instead. Similarly, you can use nut butters instead of butter or margarine.
We aren't suggesting that you should forget about having water completely but having just one scoop of protein powder with water along with every meal will help you add sufficient protein to your everyday diet.
It's okay to take a few supplements if you are not able to consume certain foods. Vegetarians and vegans can greatly benefit from zinc, iron, vitamin B12, vitamin D, creatine, carnosine, carnitine, choline, taurine and algae DHA/EPA.
If you are trying to gain weight or muscle mass, having bulky vegetables such as carrots and broccoli may not be your best idea. While it is awesome that you are having these veggies, having too much may prevent you from having a variety of other protein-rich sources such as nuts, seeds, beans and whole grains. Ideally, you should have a serving of fruit and vegetables with every meal but make sure they aren't your only sources of nutrition even if you are green-lover.
Beans are packed with proteins and there are so many different kinds. Whether you choose kidney beans or soy-based protein such as tofu and soy patties, you can be sure you that you are having enough and more protein with a particular meal. Don't be afraid of canned or frozen beans because convenience sometimes helps in the sustainability of a diet but having them fresh is always better.
