Almost every chai recipe includes ginger, cinnamon, cloves and black, or green tea. Other common chai tea ingredients are cardamom, black peppercorns and fennel. All of these are considered healthy ingredients in Ayurvedic medicine. Milk, which is almost always part of chai tea, enhances the taste and makes it a richer, more satisfying beverage. Ayurveda says that poor digestion contributes to many ailments, so strong digestion is vitally important. The spices usually found in chai help stimulate, balance and support digestion. Cinnamon and ginger helps to calm the stomach, nausea, and diarrhea. Cloves even stimulate digestion.
