The problem of constipation is being treated by this process of colon cleansing from many earlier centuries. The effectiveness of this treatment mainly depends on the type of enema used. Enemas are used to remove the waste material only from the lower part of the colon. Enemas are also useful in emptying the rectum. The different types of enemas are water enemas, coffee enemas, clay enemas, etc. Most people do not like inserting enemas through their rectal cavity. http://lifebrandmedia.com/the-benefits-of-colon-cleansing/
