Colon Rx uses two proven ingredients to improve bowel motility and tonicity in people with occasional constipation. Magnesium hydroxide is a well known ingredient in laxative and antacid formulas, while Triphala is a classic formula in Ayurvedic medicine. Colon Rx can be used for short periods of time as a fast-acting mild laxative for occasional constipation, or as a daily bowel tonic to help strengthen and tonify the bowels. Details Highlights - Magnesium hydroxide, a well known ingredient in laxative and antacid formulas, works by osmosis, drawing water from surrounding tissues to the intestines. This local increase of water not only softens the feces but actually increases the volume of the feces -which promotes intestinal motility. - Triphala, a classic formula in Ayurvedic medicine, consists of three fruits: Amalaki, Bibhitaki, and Haritaki. Amalaki (known as Indian gooseberry or amla) is a strong natural antioxidant and is considered one of the best rejuvenating herbs in Ayurveda. Haritaki has the strongest laxative powers of these three fruits. The herb also has astringent properties and balances Vata. Bibhitaki is an excellent rejuvenative, with both laxative and astringent properties. It eliminates excess mucous, balancing the Kapha dosha.
