Homeopathy is a hoax, so how could such a doctor not be a "quack"? There is also no such thing as a liver "detox", nor is there any way to fix to lactose intolerance.quote:After years of looking for answers to digestive problems, I tried a homeopathic Dr.(not a quack) who insisted I have to have colon clean and liver detox. He said it will fix me up and even get rid of lactose intolerance.
