No. The word "tea" in English originally meant only drinks made from the tea plant (Camellia sinensis). Chamomile, peppermint, rooibos, hibiscus, and similar are correctly called "herbal infusions" or "tisanes". Most retailers (us included) call them tea anyway because everyone knows what you mean.

Yes, every herbal infusion we stock is genuinely zero caffeine. The exceptions to know about: yerba mate (caffeinated, listed under herbal in some shops), guayusa (caffeinated, similar). We list both under separate caffeinated herbal labelling so there are no surprises.

There is some evidence (small studies, modest effect sizes) that the apigenin in chamomile binds mildly to GABA receptors, producing a relaxant effect. It is not a sleeping pill. Drinking a cup half an hour before bed as part of a wind down routine works for many people, partly because of the apigenin and partly because the routine itself signals the brain.

It is supplying flavoured hot water plus a mix of herbs traditionally associated with digestion (fennel, peppermint, liquorice). UK food law prohibits explicit medical claims so the packaging speaks of "support" rather than "cure". We stock these because customers like them and the herbs are genuinely there; we do not promise they will replace a balanced diet.

Pukka is British (Bristol, founded 2002), entirely organic, mostly wellness focused with some single herbs. Yogi is American (founded 1969 by a yoga teacher), a mix of organic and conventional, broader range including chai variants. Both make solid herbal blends, Pukka leans more "British apothecary", Yogi more "Californian wellness".
