From the Mate Factor Caffeine Free USDA Herbal Tea Certified by: QCS Turmeric is a powerful antioxidant, anti-fungal and antibacterial agent. Black Pepper is rich in piperine. Piperine makes Curcumin (the main ingredient in Turmeric) more bioavailable to the cells. Studies indicate that piperine exponentially increases the bioavailability of curcumin. We have combined these with a healthy dose of Ginger (closely related to Turmeric). Ginger is a powerful antioxidant and circulation stimulant to help the useful properties of all the herbs get to the cells. Combining these herbs with stomach soothing Peppermint & Lemongrass results in a delicious, powerful healing tea.
