Sensiblehealth.com is where I get all of my Chinese herbs. Seems like I have read on that site that folks who were having gallbladder attacks were able to use the Gold Coin Grass to knock them out. I wondered if that might be more helpful to you since I think you posted that the Epsom Salts were not that helpful.
I am taking the bitters and gcg mainly as preventive therapies. I have not had a gallbladder attack that I am aware of. I used to have terrible pains in my left side when I was pregnant, but nothing after that. This was several years ago.
On Julia's site, I think she has even given reports of folks who have gotten rid of their stones slowly without the flushes. Thanks.
