Talbina Flakes

Talbinah is actually a broth made from barley (Sha`eer). The broth is called Talbinah because it is thin and white, similar to milk.
Barley (the essence of Talbinah) is a rugged cereal grain from the grass family, it can grow up to 1 ½ to 4 feet tall and flourishes in cool climates.
Evidence
Talbinah has been mentioned in many narrations of the Prophet [peace be upon him] such as the narration of Aisha that when someone from her relatives died, the women would gather for that (reason) then they would disperse except her family, she would order an earthenware pot of talbinah be cooked, then tharid (a dish made form meat and bread) would be made and the talbinah poured over it. Then she (Aisha) would say (to the women), ‘Eat from it for indeed I heard the Messenger of Allah [peace be upon him] say: “Talbinah is a relaxation for the heart of the sick person and it removes some of the sorrow”.’ [Bukhari 479/9, Book of Food, Chapter of Talbinah]
Aishah (may Allah be pleased with her) also said: the Messenger of Allah [peace be upon him] said:, “You must have what you find unpleasant but beneficial: the talbinah.” She further said – “whenever one of the family of the Messenger of Allah [peace be upon him] was troubled with sickness, the pot never left the fire until he reached one of two extremes.”, [Ibn Majah #3446] Ibn Qayyim explained this means until he or she recovered or died.
From the hadeeth of Umm Kulthum who heard Aisha (may Allah be pleased with her) saying, the Messenger of Allah [peace be upon him] said: ”You must have what you find unpleasant but beneficial (i.e. talbinah); by the One in Whose Hand is the soul of Muhammad, indeed it cleanses the stomach of one of you, just as one of you washes his face from dirt, with water.”[Sunan An Nisai Al Kubra, #7575 and Mustadrak Ala Saheehayn, by Abu Abdullah Muhammad ibn Abdullah al Haakim An-Naisaburi,Book of Food, #7531].
