ChaparralFind ProductsAlso indexed as:Larrea tridentata  © Martin WallBotanical names: Larrea tridentataHow It WorksThe major lignan in chaparral, known as nordihydroguaiaretic acid (NDGA) is a potent antioxidant and was thought by some scientists to be a potential cancer treatment. In a rat study, NDGA and a leaf extract of a South American subspecies of chaparral were found to exert an antitumor effect.4 However, one report suggests that NDGA may stimulate further growth of tumors in cancer patients.5 Clinical trials, therefore, are still needed to establish whether chaparral is a safe and effective treatment for people with cancer. Other reported effects for chaparral include anti-inflammatory properties6, 7 as well as antimicrobial actions in test tubes.8 These actions have note been established in human clinical trials How to Use ItA tea can be prepared by steeping 1 teaspoon (approximately 5 grams) of leaves and flowers in 1 cup (250 ml) of hot water for ten to fifteen minutes.9 People should drink three cups per day for a maximum of two weeks unless under the care of a physician expert in the use of botanical medicines. Alternatively, 0.5–1 ml of tincture can be taken three times per day.10 Topically, cloths can be soaked in oil preparations or tea of chaparral and applied several times per day (with heat if helpful) over the affected area. Capsules of chaparral should be avoided. Copyright © 2025 TraceGains, Inc. All rights reserved. Learn more about TraceGains, the company.
