Fenugreek

Fenugreek is a seed from a clover-like plant, used for centuries in cooking and traditional medicine, that contains fibre and plant compounds called saponins thought to act on hormones and digestion. Most people look at it for breast milk production, and the evidence is moderate: in two small studies of 164 mothers, milk production went up. Those trials mostly tested herbal teas that combined several ingredients, so it is hard to credit fenugreek alone.
