Peppermint oil is one of the best-supported botanical agents for abdominal discomfort, particularly in IBS. A meta-analysis of 12 RCTs (835 patients) found peppermint oil significantly improved global IBS symptoms and abdominal pain versus placebo. Its active constituent menthol blocks L-type calcium channels in gut smooth muscle, reducing colonic spasms.
Peppermint oil relaxes the lower esophageal sphincter (LES), which can worsen acid reflux and heartburn in GERD patients. Clinical evidence shows esophageal exposure to menthol prolongs LES relaxation significantly compared to normal swallowing. Enteric-coated formulations bypass the LES and are used for IBS without triggering reflux. Peppermint has strong evidence for functional dyspepsia (upper GI discomfort), a distinct condition from GERD.
Peppermint contains significant concentrations of phenolic antioxidants — primarily rosmarinic acid, eriocitrin, luteolin, and hesperidin — that confer strong antioxidant activity in vitro.
