The efficacy of triphala has not been studied for every health condition or age. For that reason, it’s important to discuss its use with your doctor prior to taking. This herb is considered unsafe for use in babies and children, the elderly, and women who are pregnant or breastfeeding. Gastrointestinal side effects, such as loose stools, have been commonly noted among people who use triphala, hence not every age group may be apt for this herb.
