Whether you’re looking for a quick and easy way to shed the pounds or you want to flush the toxins out of your colon, colonic hydrotherapy spas and wellness facilities claim they can help you do both. Every year, Americans pay between $50 and $175 for a colon cleanse to improve their health through toxin removal, says Mayo Clinic. The recent popularity of colonic hydrotherapy is due to celebrity endorsements by Jennifer Aniston, Madonna, Gillian McKeith, and the late Princess Diana who had weekly treatments, reports the Daily Mail. The colonic cleanse first reached its height of popularity more than a century ago because of its alleged health benefits for the body. However, in 1919, the American Medical Association refuted the claims of colonic hydrotherapy as a treatment for autointoxication, ruling out toxins as the main cause of illness.
