Blue Butterfly Pea Flower Tea: What Makes It Turn Purple and Why It's Worth Drinking

Butterfly pea flower (Clitoria ternatea) contains anthocyanins — the same pigments that make blueberries blue and red wine red. When you add lemon juice (acidic), the pH drops and the anthocyanins shift from blue to purple. Add a little more acid and it goes pink.

Beyond the color trick, butterfly pea flower is packed with antioxidants. More than blueberries, according to some studies. It supports brain function, eye health, and skin health — all without caffeine.

We blend it with our whole-leaf Assam green tea for a drink that's as functional as it is photogenic. The green tea adds L-theanine and a mild caffeine kick. The butterfly pea adds the anthocyanins and the visual drama.

If you want to see the color change yourself, try our [Blue Flower Green Tea](https://nevisan.in/products/blue-flower-green-tea). Add a squeeze of lemon and watch it turn from blue to purple. The taste is mild, slightly earthy, and completely caffeine-free.
