Fenugreek (Trigonella foenum-graecum) is an annual plant in the family Fabaceae, with leaves consisting of three small obovate to oblong leaflets. It is cultivated worldwide as a semiarid crop. Its seeds and its leaves are common ingredients in dishes from South and Central Asia. Fenugreek is used as a herb, spice, and vegetable. Sotolon is the chemical responsible for fenugreek's distinctive sharp smell. Fenugreek is sometimes used as animal feed. It provides a green fodder palatable to ruminants. The seeds are also used to feed fish, domestic rabbits and ruminants.
