Is quackery, its BS, it has no basis in anything beyond your belief it will help you, and if you are like most people, no amount of logic will dissuade you. You are looking for someone to give you an affirmation and make you feel better about it.

One of the common responses is that its biased doctors and evil pharmaceutical companies who try to 'suppress' holistic medicine. What it is is conscientious doctors trying to educate the public vrs the unsubstantiated lies of a 16 BILLION dollar a year industry in the US known as alternative medicine.
