The organic butterfly pea flower or Blue Matcha is a flower from South East Asia that is known to turn a simple infusion into a bright blue herbal tea. Its wonderful colour is in fact used as a natural food colouring: colours rice, desserts or smoothies in a smart and healthy way.
The Clitoria Ternatea plant
Anchan, as blue tea is called in Thailand, has many names around the world: Butterfly pea, blue Matcha – or in Latin: Clitoria Ternatea. This plant, which belongs to the genus Vicia, is a persistent element of natural medicine in Asia. The positive effects are attributed to its flowers and roots. In Ayurvedic medicine, blue tea is used to improve memory, against stress and as a mood enhancer.
But Anchan is also simply fun: the deep blue colour comes out best in an infusion of boiling water and a glass container. A few flowers are enough to colour a cup deep blue. Children love it as a refreshing bright blue drink. A squeeze of lemon (or other acid) colours the tea purple, while alkaline additives make it glow green.
