I also got GCG from Sensible health in Toronto. Shipping to Michigan/US was very reasonable, I don't know about UK. Julia did say on her web site that she thought it could be used long term to slowly dissolve stones vs. flushing. Does anyone know if that is true? I took the bitters and GCG grass for awhile about a year ago, and then chickened out on the flush. I had trouble with the alcohol, even that little bit, giving me a headache. Guess that means a compromised liver. She seemed to feel that alcohol extracts were more effective because they go right to the liver, you can refer to her web site for her reasoning on that. I don't know if other health practitioners would concur. There is a lot of conflicting information out there. In Sandra Cabot's book on Liver Cleansing
diet, she thinks alcohol extracts should be avoided, particularly long-term, because they are hard on the liver.
