What is talbeenah? How can it be used as a remedy?
Question

                I hope that you can tell me the method of using talbenah as a remedy as described in Prophetic medicine.
Praise be to Allah.Talbeenah is mentioned in 
    a number of saheeh ahaadeeth, such as the following: 

    (a) 

    It was narrated from ‘Aa’ishah, the wife of the Prophet  
    (peace and blessings of Allaah be upon him), that if a member of her family 
    died, the women would gather together, then they would depart, except her 
    own relatives and close friends. She would order that a pot of talbeenah be 
    cooked, then some thareed would be made and the talbeenah would be poured 
    over it. Then she would say: Eat some of it, for I heard the Messenger of 
    Allaah  (peace and blessings of Allaah be upon him) say: “Talbeenah 
    soothes the heart of the sick person, and it takes away some of the grief.” 
    Narrated by al-Bukhaari, 5101; Muslim, 2216. 

    (b) 

    It was narrated from her (may Allaah be pleased with her) 
    that she would order that talbeenah be made for the sick and the one who was 
    mourning a death, and she used to say: I heard the Messenger of Allaah  
    (peace and blessings of Allaah be upon him) say: “Talbeenah soothes the 
    heart of the sick and takes away some of the grief.”

    Narrated by al-Bukhaari, 5365; Muslim, 2216 

    It is clear from these two hadeeths that talbeenah is used to 
    treat the sick and to reduce the grief of one who is grieving, soothing his 
    heart and giving him energy. 

    Talbeenah is a broth that is made from two spoonfuls of 
    barley flour with bran, then a cup of water is added to that and it is 
    cooked over a low fire for five minutes. 

    Some people add a spoonful of honey to it. 

    It is called talbeenah because it is like milk (laban) in its 
    whiteness and consistency. 

    Ibn al-Qayyim said: 

    If you want to know the virtue of talbeenah, then think of 
    the virtue of barley water, for it is barley water for them. It is a soup 
    that is made from barley flour with bran. The difference between it and 
    barley water is that the latter is made from whole grains, whereas talbeenah 
    is made from flour, which is more beneficial as the properties of the barley 
    are released through grinding. We have mentioned above that habits have an 
    effect on whether medicines and foods are of benefit. It was the habit of 
    the people to drink barley water made from flour rather than whole grains, 
    which is more nourishing and effective… end quote. 

    Zaad al-Ma’aad, 4/120 
Al-Haafiz ibn Hajar (may 
    Allaah have mercy on him) said, describing talbeenah: 
It is a kind of food that 
    is made from flour or bran, to which honey may be added. It is so called 
    because it resembles milk in its whiteness and consistency. Its benefit is 
    that it is soft and well-cooked, not hard and raw. End quote. 

    Fath al-Baari, 9/550 

    There is no doubt that barley has many benefits, some of 
    which have been discovered in modern studies, such as: lowering cholesterol, 
    treating the heart, treating depression, treating high blood sugar and high 
    blood pressure, softening the stools and soothing the colon. Studies have 
    also demonstrated the importance of barley in reducing the incidence of 
    colon cancer. 

    Dr. Sahba’ Bunduq said – after noting the benefits mentioned 
    above and discussing them in detail: 

    In this sense, talbeenah is a protection against diseases of 
    the heart and circulatory system, as it protects the arteries from 
    arteriosclerosis – especially the major arteries of the heart. It also 
    protects against angina, reduction of blood supply and cardiac infarction. 

    As for those who have actually been affected by these 
    vascular and cardiac problems, talbeenah, with its health benefits, can play 
    an important role in preventing their symptoms from getting worse. This 
    shows the miraculous nature of the words of the Prophet  (peace and 
    blessings of Allaah be upon him): “Talbeenah soothes the heart of the sick.”

    And Allaah knows best.
