There is some evidence to suggest that it may directly prevent atherosclerosis in rats via modulating cholesterol metabolism, help with allergies in humans, and may be a decent anti inflammatory. Additionally, it is biochemically plausible that it may be an anti-hypertensive. However, the jury is still out on the clinical effect- if any- of this supplement in humans based on my interpretation of the data. I don't know if I have a strong enough feeling one way or another currently, unfortunately.
