Colon cleansing involves the use of a colon cleanser, usually a commercial product which may be chemical-based or a product that contains one or more natural ingredients which are claimed to have cleansing properties. Some people take a fiber shake; a liquid containing natural, high-fiber ingredients. They may start by having just one a day. Some will gradually increase their intake to three or even five times a day over a period from two to four weeks.
Some people prefer to use commercial colon cleansers like OxyPowder®, Colonix® or Dual Action Cleanse®.
You might also use one of several available herbal “natural colon cleansing” preparations.
Their users say that they may be less harsh on your body than the chemical based products and may provide a more thorough cleansing. Many of these products are oxygen-based colon cleansers.
Stabilized oxygen therapy is claimed by some people to clean the entire colon by removing the old impacted fecal matter and to detoxify your body. They say that some fiber products, including Psyllium, may only flush out only the larger debris clogged within your colon. I am not aware of any definitive tests which would support these claims.
