Asteracantha longifolia (synonymous with quite a few other plant and traditional names) is a traditional Indian medicine that is reported to be beneficial against glucose disturbances (Diabetes) and against liver problems; in addition to these two therapeutic claims, it is reported to be a diuretic and an aphrodisiac.
At this moment in time there is not much information on this herb, but it appears to have some interactions with glucose metabolism in the sense that it can augment glycogen synthesis in the liver and muscle tissue (mechanism unknown) and it appears to protect the liver and brain from lipid peroxidation with a potency somewhat comparable to Vitamin E.
