Washing your body is rejuvenating and a commonly accepted hygienic practice. A colonic is an internal shower of water for the colon, relieving stresses and burdens from the waste it carries. Cleansing it supports all the other organs of elimination: the liver, kidneys, lungs, lymph and skin. With more than 60% of your immune system in your intestines (Jesse Hanley, MD), colon cleansing can contribute to your overall health and well-being.
