Bitter melon (Momordica charantia) is a gourd. In Anatolia the ripe fruit is steeped in olive oil and used for stomach complaints; no clinical study supports this. Small clinical studies found bitter melon preparations modestly lowered blood sugar in type 2 diabetes, though less than medicines. It must not be used in pregnancy because of miscarriage risk.
