Used by the old school body builders. Good product.

It is difficult to find if you don't have a well stocked herbalist in your neighborhood, so ordering through amazon is a great convenience. The flavor has a slight astringent bitterness to it, which i actually do like.

It's to the point where it is no longer bothersome. I take it for my allergies, as it keeps the swelling down in my sinus cavities, thus preventing a sinus infection. It is also great for urinary tract.
