I do not take herbs to aid my flush, but I do take Milk Thistle for liver health. I eat Turmeric everyday in my food and take one tea spoon everyday with my Vitamin C if I am flushing or not.
GCG is widely used in tincture form.
Some herbs are for healing and some herbs are to aid the cleanse. GCG in particular, is used to break up the gall stones. Turmeric, Milt Thistle, Dandelion, etc. are to rejuvinite the liver. Liver Flush is great every year once or twice for maintenance. If one is trying to clear up some conditions, like depression, high blood pressure, not able to digest fats, etc. would benefit from Liver Flush on regular interval of to to three weeks till all the stones and junk is cleaned out.
