This was originally uploaded into youtube on July 4, 2016 3:06 AM Essiac was an extract specifically for the trial. Ideally If I were to use these kinds of extracts with things like burdock, rhubarb and sheep sorrel, I'd like for them to be extracts that had their oxalates reduced or eliminated while keeping the good stuff or at least add citric acid to them.. Honestly, you could just stick with the Turkey Tail, Astragalus and Turmeric. 2 ounces of Turkey Tail 20:1 Concentrated Extract, 1/2 ounce of Turmeric and add Astragalus according to preference, I'd start out at 1 tablespoon. Now this is purely educational and I wanted to show you guys a skill of mine and I'm not promoting this as medical advice. If you do this and something happens I won't be responsible for it, you were warned.
