Gentle cleansing of the intestines using naturopathic methods Do you have symptoms due to irritable bowel syndrome, allergies, neurodermatitis or food intolerance, or just want to detoxify and are currently fasting? Then an intestinal lavage (colon hydrotherapy) can help you to get these stresses under control again in the long term. It is a naturopathic method that has been tried and tested for over 50 years without drugs or chemicals to cleanse and detoxify your intestines. Especially with fasting cures or liver detoxification, colon hydrotherapy is a gentle and very useful accompanying measure.
