I have read on this forum about the effectiveness of Chinese Bitters, Gold Coin Grass, Bupleurum, and Chanca Piedra, to help support liver flushing. But the only links I have seen for these herbs is for Sensible Health - Julia Chang. Now, is that the only place to get these herbs? I would think that if they are that so effective, that you could find them in your local well-stocked health food store. But my local health food stores have never heard of them. Do I need to seek out a Chinese Herbalist? I guess I am just looking for some validation that these are safe to take.
