How it works, mechanistically.
Core mechanism
Menthol relaxes gastrointestinal smooth muscle primarily through calcium-channel effects and TRPM8 signaling, reducing spasms and visceral discomfort. Enteric coating delays release until the small intestine, lowering heartburn risk compared with non-coated oil. If released in the stomach or esophagus, peppermint oil can relax the lower esophageal sphincter and worsen reflux.
Dosing & protocol.
Usually taken 30-60 minutes before meals. Swallow whole; chewing or crushing defeats enteric coating and increases heartburn risk.
