Peppermint is one of the most widely studied herbal supplements, with a long history of traditional use and a growing body of modern research supporting several of its applications. Studies indicate that enteric-coated peppermint oil capsules may help ease symptoms of irritable bowel syndrome, including abdominal pain and bloating, and research suggests the menthol component contributes to its potential benefits for digestive comfort, nausea relief, and sinus congestion. Topical application of diluted peppermint oil has also been explored for tension headache relief, while its aroma has shown preliminary promise for supporting focus and alertness. Available as oil capsules, leaf tea, and menthol-based preparations, peppermint remains one of the more versatile and well-researched options in the herbal supplement space, though individual responses can vary.
