What it is, and the colour trick

Butterfly pea is an infusion of the dried blue flowers of Clitoria ternatea, botanically a tisane rather than true tea and naturally caffeine free, see what counts as tea. The viral appeal is the colour: it brews a vivid blue from natural anthocyanin pigments, and adding lemon or any acid shifts the pH so it turns purple to magenta in front of you, genuine chemistry rather than an additive. On taste it is mild, earthy, slightly woody and fairly neutral, which is precisely why it is usually sweetened, paired with lemongrass, ginger or fruit, or used in cocktails, lattes and as a natural blue colouring: the flavour is the supporting act and the colour is the star, so treat it as a base and a spectacle rather than a standalone flavour tea.

The benefit claims, and the blue lotus safety point

It contains antioxidants and has a long traditional Ayurvedic use, both true, but the mood, memory and anti ageing claims circulating online are early and overstated, typically resting on concentrated extract laboratory work that does not translate to a cup of flower infusion, see claim scepticism. So enjoy it and do not medicalise it: a pleasant, harmless, caffeine free, photogenic drink with no special powers in cup form, low risk in normal amounts with the usual sensible caution around pregnancy, medication and concentrated extracts. The single most important point is that this is not "blue lotus", an unrelated, mildly psychoactive plant with variable, evolving legal status that trend content routinely conflates with the harmless blue butterfly pea drink, see blue tea vs blue lotus.

How to use it

Steep the dried flowers in hot water, strain, then split a glass and add citrus to one half for the colour show; it is excellent over ice and as a natural blue base for lemonades and mocktails, see the iced tea method.
