Salacia oblonga for type 2 diabetes
A tropical shrub used in Ayurveda for controlling obesity and its associated health complications, Salacia oblonga (a.k.a. Saptrangi) has shown promise in some limited trials that looked at its ability to reduce high blood sugar in diabetes. A new trial goes into more detail: the extract of the root and stems of this plant lowered post-meal blood glucose by about 25%, while also reducing the amount of circulating insulin in the blood. Thus, it seems to sensitize the physiology to insulin, which reverses the trend of insulin resistance seen in type 2 diabetes. A 25% reduction is significant: it could bring a diabetic patient with postprandial blood glucose levels over 150 down to the "normal" range of 120.
