At a glance
Ancient Egyptian, Greek, and Roman texts all reference mint for digestive comfort — a use that has persisted essentially unchanged into modern enteric-coated peppermint oil capsules.
Peppermint is a natural hybrid of watermint and spearmint, prized since antiquity for its cooling menthol flavor. The essential oil, concentrated in the plant's leaves, is what gives peppermint its characteristic sharp, cooling sensation — and its long association with digestive comfort.
Because peppermint oil can relax smooth muscle, it's traditionally taken after meals, often in a slow-release capsule designed to reach the intestine rather than dissolve in the stomach.
