I have never tried a Liver Flush but I am allergic to some liver things like milk thistle Watermelon I noticed on one as well. A friend of mine had liver failure from one because she use an antihistamine with hers. Her heptic dr said most people are not aware of this and Tylenol as causing so many liver failures. I have used those so much with the hives and allergies that I won't go there. Have fatty liver and fatty pancreas as well as an enlarged spleen. Yeah I know trying to eat myself to death. I have lost over 80lbs changing what I eat to vegan but feel so much healthier sometimes during fast than when I am eating that I long to detox and get it all out. Realizided the nightshade is a problem with pain just before fasting. Going to miss my tomatoes something terrible.
