Butterfly pea flower tea, commonly known as blue tea, is a caffeine-free herbal tea, or tisane, beverage made from a decoction or infusion of the flower petals or even whole flower of the Clitoria ternatea plant.
It is also rich in anthocyanins, which are the antioxidant compounds responsible for its unique color.
For this reason, manufactures may use butterfly pea flower in cosmetics or as a natural dye for foods, drinks, and textiles.
The flowers are also commonly brewed into an herbal tea, often alongside ingredients like lemongrass, honey, and lemon.
When the acidity of the pea flower tea changes, the color changes as well. This quality makes butterfly pea flower a popular ingredient among mixologists for specialty cocktails
