Synopsis

Source of validity: Scientific
Rating (out of 5): 3

Peppermint oil has a scientifically supported use for alleviating certain types of cramps and spasms, particularly those related to the gastrointestinal (GI) tract. The main active component in peppermint oil, menthol, has antispasmodic properties. It works by relaxing the smooth muscles of the GI tract through calcium channel blockade, which can help relieve symptoms like abdominal pain, cramping, and spasms. Clinical studies, including randomized controlled trials, have shown that enteric-coated peppermint oil capsules can reduce symptoms in patients with irritable bowel syndrome (IBS), such as abdominal cramping and discomfort.

Peppermint oil has also been used traditionally for muscle cramps and spasms, often as a topical application, but scientific evidence for its effectiveness outside the GI tract is limited. Most high-quality research focuses on digestive-related cramping. For example, a 2014 meta-analysis published in BMC Complementary and Alternative Medicine concluded that peppermint oil is effective and safe in the short term for relieving IBS symptoms, which include spasms and cramping. However, evidence for its effectiveness in other types of muscle spasms, such as menstrual or skeletal muscle cramps, is sparse and mostly anecdotal.

In summary, peppermint oil’s use for GI-related cramps and spasms is supported by moderate scientific evidence, earning a rating of 3. Its effectiveness for other types of cramping remains less substantiated and requires further research.
