Thanks for responding. Did the Chanca Piedra that you took come from Rain-Tree Health (the company that is in Europe)? Because I live in Canada and it might be hard to order from them. There is also a "Rain-Tree.com" that sells it (from the States) and looks pretty reliable. I've tried both Julia's "Chinese Bitters" and "Coptis". (I've never tried the Gold Coin Grass) I tried taking half of whatever was recommended on the bottle (so if it said to take one tablespoon once a day, I would take 1/2 tablespoon once a day, etc.) They are VERY bitter (especially the Coptis). I think she sells GREAT herbs..... WAY better than you could get in a health food store. But go slowly.... because in my experience, they are STRONG. I was never able to take them for more than a couple days in a row because they seemed to "release toxins" like crazy. I could be totally wrong about what was going on, but that is how it FELT. Good luck to you. Let me know how it goes for you.
