Natural Cleanse Plus is a supplement designed to detoxify the body by cleansing the colon. Flushing parasites and mucus from the colon can improve digestion, help the body absorb nutrients, and relieve health issues, according the company's website. However, there is insufficient research to substantiate these claims, according to WebMD.
The theory that undigested food causes mucus to form in the large intestine, creating toxins that enter the bloodstream and poison the body, is based on an ancient belief called autointoxication, according to WebMD. However, because natural bacteria in the colon help detoxify food waste, and because the colon sloughs off its old cells approximately every three days, there is little chance for harmful materials to accumulate.
