The usual colonic irrigation lasts about 45 minutes. All tubes are disposable. An FDA-approved colonic machine with a sophisticated water filtration system. After gentle insertion of the speculum (we show each client how to insert the tubing-it is very simple), it is attached to two plastic tubes. One brings the clean, filtered water into the body and the other carries out the waste, gas, undigested foods, parasites, yeast, etc. The therapist then adjusts the water pressure (very gentle flow) and the temperature.
