Peppermint is the one cup with real IBS evidence behind it. The tea is milder than the enteric-coated oil capsules clinicians use, but it is gentle and worth trying. Caffeine, by contrast, can aggravate IBS for many people.
Why peppermint helps
Menthol relaxes the smooth muscle of the gut wall, which eases the cramping and spasm typical of IBS. Peppermint oil is well enough evidenced that it appears in clinical guidance. Tea delivers a gentler dose than capsules, so it is a reasonable everyday option. See Wikipedia: peppermint, the NHS guide to IBS, and NICE guideline CG61.
Watch the caffeine
Strong black and green tea contain caffeine, a common IBS trigger that can speed the gut and worsen urgency or pain. If you have IBS, lean towards caffeine-free herbals and keep any caffeinated tea weak and modest.
Other gentle cups
- Fennel for the bloating and wind that often come with IBS.
- Ginger for associated nausea.
- Chamomile as a mild, soothing all-rounder.
