Tea and digestion, at a glance

Tea	What it genuinely does
Peppermint	well evidenced antispasmodic; eases bloating and gut spasm
Ginger	one of the best evidenced herbals for nausea and digestive comfort
Fennel	traditional carminative; gently anti bloating, the classic after meal cup
Chamomile	mild, soothing, traditional gut settler; gentle
Strong black, late / on empty stomach	tannins can aggravate reflux in some; a real individual caution, not universal

None of these is a cure for a diagnosed digestive condition: the effect is real but modest comfort and gentle support, not treatment, so anyone with a persistent or diagnosed gut problem should treat tea as comfort alongside medical advice rather than instead of it. This is general information, not medical advice.

Curator's note: digestive tea is one of the most evidence supported tea categories. The post meal cup is genuinely useful, not folklore. Worth keeping Pukka After Dinner or peppermint in the cupboard. Lee, Teas.co.uk, Tunbridge Wells.
