Larrea-ClearTM is made from the leaves of Larrea Tridentata, known for thousands of years by the Native Americans of the desert Southwest as a healing herb. The supplement can be used for immune support. Larrea-ClearTM is different from other similar products because the harmful constituent of the raw Larrea Tridentata leaves is neutralized using a proprietary process.
