Talc, or talcum, is a clay mineral, composed of hydrated magnesium silicate with the chemical formula Mg3Si4O10(OH)2. Talc in powdered form, often combined with corn starch, is used as baby powder. This mineral is used as a thickening agent and lubricant. It is an ingredient in ceramics, paints, and roofing material. It is a main ingredient in many cosmetics. It occurs as foliated to fibrous masses, and in an exceptionally rare crystal form. It has a perfect basal cleavage and an uneven flat fracture, and it is foliated with a two-dimensional platy form. The Mohs scale of mineral hardness, based on scratch hardness comparison, defines value 1 as the hardness of talc, the softest mineral. When scraped on a streak plate, talc produces a white streak; though this indicator is of little importance, because most silicate minerals produce a white streak. Talc is translucent to opaque, with colors ranging from whitish grey to green with a vitreous and pearly luster. Talc is not soluble in water, and is slightly soluble in dilute mineral acids.Soapstone is a metamorphic rock composed predominantly of talc. Etymology
The word "talc" derives from Medieval Latin talcum, which in turn originates from Arabic: طلق ṭalq which, derives from Persian: تالک tālk. In ancient times, the word was used for various related minerals, including talc, mica, and selenite. Formation
Talc dominantly forms from the metamorphism of magnesian minerals such as serpentine, pyroxene, amphibole, and olivine, in the presence of carbon dioxide and water.
Amoxicillin/clavulanic acid, also known as co-amoxiclav or amox-clav, sold under the brand name Augmentin, among others, is an antibiotic medication used for the treatment of a number of bacterial infections. It is a combination consisting of amoxicillin, a β-lactam antibiotic, and potassium clavulanate, a β-lactamase inhibitor. It is specifically used for otitis media, streptococcal pharyngitis, pneumonia, cellulitis, urinary tract infections, and animal bites. It is taken by mouth or by injection into a vein.Common side effects include diarrhea, vomiting, and allergic reactions. It also increases the risk of yeast infections, headaches, and blood clotting problems. It is not recommended in people with a history of a penicillin allergy. It is relatively safe for use during pregnancy.Amoxicillin/clavulanic acid was approved for medical use in the United States in 1984. It is on the World Health Organizations List of Essential Medicines. The World Health Organization classifies amoxicillin/clavulanic-acid as critically important for human medicine. It is available as a generic medication. In 2019, it was the 93rd most commonly prescribed medication in the United States, with more than 8 million prescriptions. Medical uses
Amoxicillin/clavulanic acid is widely used to treat or prevent many infections caused by susceptible bacteria, such as:

urinary tract infections
respiratory tract infections
skin and soft tissue infections
sinus infections
tonsillitis
cat scratches
infections caused by the bacterial flora of the mouth, such as:
dental infections
infected animal bites
infected human bites (including uncomplicated "clenched-fist" or "reverse-bite" injuries)It is also used for tuberculosis that is resistant to other treatments.
