Also known as colonic irrigation, this practice was reputedly used in Ancient Egypt, China and India. However, the method common in the West today has its origins in 19th century European Spas. The treatment is conducted lying down, whilst warm purified water is introduced into the colon via the rectum. Once this is completed, the therapist uses special massage techniques to stimulate the release of the water. The whole process takes between 30-45 minutes and has the effect of cleansing the bowels from built-up toxins, bacteria, parasites and other unwanted substances.
