Fenugreek is used both as an herb (the leaves) and as a spice (the seed). The yellow colored fenugreek seed, commonly called methi, is frequently used in the preparation of pickles and curry powders. The young leaves and sprouts of fenugreek are eaten as greens. Fresh or dried leaves are used to flavor dishes. Fenugreek is mainly used as digestive aid. It is ideal for treating sinus, lung congestion, reduces inflammation and fights infection.
