A colonic (as Edgar Cayce so often referred to this procedure) is an internal bath using a professional machine to cleanse the colon. Current scientific evidence shows that a properly functioning colon is beneficial to overall health.
During a colonic, warm, filtered water is gently infused into the colon and then released, in a series of fills and flushes that generally continue for 40 to 45 minutes. The equipment is a closed system with disposable tubes and fittings; the out-bound tubing allows you to remain on the treatment table for both infusion and release. 7 years ago
