Butterfly pea is a caffeine-free herbal tea with a calming effect that can also support stable blood sugar levels and skin health. Its vibrant blue color comes from anthocyanin, which act as powerful antioxidants. Drinking butterfly pea tea may be good for brain function, eye health, and hair growth due to its high concentrations of antioxidants and other compounds. Brew the flowers by themselves, add them to other herbal teas, or drop a few in a pot of rice before cooking for the most beautiful blue cloud rice!
