Butterfly Pea Flower 101: The Tea That Changes Colour

If you've seen a cup of tea turn from deep blue to violet on your feed, that's butterfly pea flower — and it's not a filter trick. The colour change comes from anthocyanins, natural antioxidant compounds that react to pH. Add lemon (acidic) and watch the shift happen in real time.

Beyond the visual, butterfly pea is naturally caffeine-free and has been used traditionally to support relaxation and skin health. MLUE's blend uses 100% whole dried flowers — no dust, no fillers — so you get a clean, purely botanical infusion.

Try it hot for a calming ritual, or iced with lemon for the full colour-changing effect.
