Butterfly Pea powder, or blue matcha as it is sometimes called, comes from the flowers of the Butterfly Pea plant. It is a beautiful flowering vine native to Thailand, Burma, and other parts of Southeast Asia, and has powerful anthocyanins, which are the antioxidant compounds responsible for its unique color. Commonly brewed into an herbal tea, the taste is light and floral, similar to chamomile or jasmine tea. However, it is very versatile and can be mixed with your other favorite tea ingredients for the perfect cup Butterfly pea flowers are rich in anthocyanin compounds called ternatins, which give the plant its uniquely bright color. Test-tube studies suggest that ternatins can alleviate inflammation and may prevent cancer cell growth.
