The procedure of colon hydrotherapy has been around for centuries with the Egyptians first using it around 1500 BC. The Egyptian papyrus method utilized a combination of purgatives, enemas, diuretics, heat, and steam, while both ancient and modern tribes from the Amazon, Central Africa, and remote parts of Asia, have also used river water for bowel cleansing.
The founding fathers of Western medicine, Hippocrates, Galenus, and Paracelsus too used and prescribed the use of enemas for cleaning the colon. By the 1920s into the 1960s, enemas had become standard practice in hospitals worldwide. 
What is colon hydrotherapy?
Modern hydrotherapy is a complete and deep clean-up technique applied to the large intestine using pressurized water. It implies the utilization of a sophisticated machine that regulates the pressure, temperature, and water carefully infused into the colon.
The process destroys mycosis (fungus) attached to the walls of the colon and helps to detoxify the intestinal lymphatic glands, thereby balancing the immune system and decreasing allergic symptoms.
By eliminating the fecal incrustations in the haustra (small pouches), hydrotherapy also favors peristalsis, improves the muscle tone of the colon, and relieves constipation. 
During a session of colon hydrotherapy, several things happen: water temperature is alternated from cold to warm, abdominal massage is performed by the therapist while the implantation of herbs or probiotics can enhance efficacy and protect intestinal flora.
Hydrotherapy also favors the blood irrigation of abdominal organs, the neutralization of free radicals, and the use of butyrate by the colonocytes, which is essential to these cells for their proper functioning. As well, impurities adhered to the wall that are putrefied and sometimes stay for long periods inside the body, are eliminated from the colon.
For doctors and therapists, colon hydrotherapy provides important information about the digestive health of the patient and allows for the detection of intestinal parasites. It also provides optimal preparation of the colon, facilitating a more accurate study for medical diagnosis and minimizes discomfort caused by residual barium.
Hydrotherapy is also highly valuable for the preparation of intestinal surgery patients, providing an optimal surgical environment.
Colon hydrotherapy as an adjuvant treatment
For cancer patients, colon hydrotherapy is an excellent adjuvant treatment.  It helps eliminatory pathways in the liver and, of course, the colon, through which the body will get rid of damaging toxins and free radicals. As well, it fights inflammation, thus helping to reduce pain.
When a patient is receiving conventional chemo or radiotherapy, colonics will protect him or her against some of the toxic effects of such therapies. At the same time, less toxicity will allow the patient to better benefit from the nutrients in food, and facilitate the action of the different nutraceuticals used in complementary medicine.
In general, colon hydrotherapy is very useful in cases of intestinal laziness, bloating, abdominal gas, diarrhea, fecalomas, constipation, intestinal cleaning after radiology, endoscopy and surgery, mucus accumulation, localized inflammatory status, intestinal parasitosis, diverticulosis, IBS, complementary treatment of arthritis, cellulitis, obesity, inadequate weight regulation, detoxification, prevention of colon cancer, prevention of polyps, venous and lymphatic disorders, tired legs and for stimulation of the body's natural defenses.
At Verita Life Clinics, colon hydrotherapy is a fast, effective, comfortable, and hygienic method of detoxifying and treating cancer patients, and forms an important part of our integrative methodology. Patients who undergo this treatment regularly report an increase in energy, better sleep, feelings of lightness and overall lifting of mood, better digestion, and healthier bowel activity.
