Fenugreek (Trigonella foenum-graecum) is a bushy herb plant with edible leaves. The seeds are also edible and useful medicinally. Fenugreek has been shown to be effective in lowering post-meal blood sugar levels. The seeds of fenugreek have 4-hydroxyisoleucine, sotolon, and trigonelline. These active compounds appear to stimulate insulin in the presence of high concentrations of glucose. According to the American Diabetes Association, the amino acid 4-Hydroxyisoleucine increases glucose induced insulin release. The seeds are slightly bitter and can be used to flavor dishes. Taking 10 to 15 grams throughout the day, with meals, is the recommended amount for effectiveness related to the control of hyperglycemia.
