i know they are expensive and a Liver Flush on it's own is very inexpensive but I haven't seen julia chang's supplements mentioned in awhile on this forum. julia chang at sensiblehealth.com has great info and chinese tinctures to aid with liver flushing. her tinctures to aid with Liver Flushing are very powerful and incredible i encourage you to check them out. i've personally have had great results with her products where as doing plain Liver Flushes have just been mediocre.
