Query: Thank you Andreas!

Andreas Moritz has provided myself, as well as my daughters, extremely valuable assistance through phone consultation and "The Amazing Liver and Gallbladder Flush" book purchased through Amazon.com. Andreas is an amazing healer, and very knowledgeable with regard to all aspects of the human body, both physical and spiritual. On three different occasions I have visited doctors/ nutritionists offices where his book is proudly displayed, and liver/ gallbladder flushes are encouraged! His detailed outline for flushing gallstones CAN heal the world, that's how powerful it is!! Thank you Andreas!!
