Several years ago I read Cure for All Diseases/Cancers...and decided I wanted to do the parasite cleanse/liver flush. I called "sources" in the back of the books to see if I could buy the walnut hulls. I thought we had to make our own tincture. I could not find anyone selling hulls, so I had to wait a year to come around for the hulls to be on the walnut trees. (I read the books in Nov 99)So late summer 2000, I was out finding walnut hulls and picked buckets of them. I ran all over town trying to find Everclear and no one had heard of it. So I used the strongest vodka I could find...100 proof? Expensive, but I was on a quest. I made the tincture, sealed in Mason jars. But couldn't find cloves. So I did the liver flush without parasite cleanse and had a rough night. Went on to other programs (i.e. colonics, etc.) and forgot about Dr. Clark and the jars of tincture. Now, I have a computer and found Curezone! Happy day! Found that many people have gone through the cleanse...with great results. I still suffer from hepatitis c, candida, and several other immune destroying illnesses. My liver is enlarged, ditto the spleen, and have gallstones seen on ultra sound. I am ready to do the cleanse and don't feel so alone this time. I bought the cloves, wormwood etc from Dr. Clark Store (still have ozone machine and zapper from before)...and also have all those jars of walnut hull tincture, extra strength. I read somewhere in Dr. Clarks' books that the tincture will last several years...it is now 2 1/2 years...and they have been in a dark closet. My QUESTION: Is the tincture still good? How long is a few years?Is it potent? Can I use it? I opened one up tonight and wow--smells potent, but it is brown in color...and I don't remember if it was always brown--I think it was always dark in color--is this correct? I still have freezer bags full of walnut balls in the freezer (I get kidded a lot about those walnut balls...one of Mom's crazy ideas...) If anyone can help me please let me know. I would appreciate any advice. Thank you in advance! Tori
