More than tea. Peppermint is one of the few herbs with strong evidence for IBS, indigestion, and tension headache — and the cool sensation isn't just flavor, it's the herb working on a real nerve pathway.

  • Strong evidence for IBS, especially as enteric-coated peppermint oil capsules
  • Eases the tight, full feeling of indigestion
  • Relaxes smooth muscle along the digestive tract, which is why it calms cramping
  • Diluted oil rubbed on the temples can ease tension headaches
  • The cooling feeling comes from menthol triggering the same nerve pathway the body uses to sense cold
  • Helps settle mild post-surgery nausea
  • Approved by Germany's Commission E for IBS

Active in Menthol, Menthone, Menthyl acetate, Flavonoids.

Skip with severe acid reflux — peppermint relaxes the muscle that keeps stomach acid down, which can make reflux worse
Skip with hiatal hernia for the same reason
Avoid with G6PD deficiency, an inherited red blood cell condition
Never apply menthol oil near an infant's face or nostrils — it can trigger a dangerous spasm of the airway
Always dilute the essential oil in a carrier oil before skin contact
Skip concentrated essential oil during pregnancy
