Planetary Herbals Triphala Internal Cleanser is a potent yet gentle formula, designed to support the body's natural cleansing process. Michael Tierra learned about Triphala while studying Ayurveda in India, and subsequently introduced it to the United States. It has been one of the most important formulas of Ayurvedic herbalism for thousands of years. Used as a household staple throughout India, Triphala is a balanced blend of three Indian herbal fruits: harada, amla, and behada. This formula is unique in that the astringent qualities of the fruits serve to tonify the colon, thereby promoting internal cleansing naturally. Available in powder, capsules and tablets.
