Triphala and Trikatu
Two ancient formulas are often used to aid the digestive system: triphala and trikatu.
More than "keeping the colon clean", triphala tonifies all the tissues of the body, especially the digestive tract, to release toxins, or ama, and carry them to elimination. It enhances the absorption and assimilation of nutrients. It balances all the elements.
Trikatu is usually taken just before a meal. One can substitute trikatu with mixing ginger, black pepper and cayenne.
