Peppermint is widely utilized for its soothing properties. While clinical evidence cannot conclusively support every purported benefit of peppermint capsules, complementary medicine practitioners have long heralded its efficacy in treating headache, indigestion, and flu symptoms.

Congestion

A known decongestant, peppermint breaks up mucus from allergies and colds. Cough and sore throat are alleviated by peppermint as well.

Indigestion

Symptoms of indigestion have been mitigated by peppermint. According to the Mayo Clinic, "Peppermint oil contains menthol, which appears to have an antispasmodic effect on the smooth muscles of your digestive tract."

Headache

Peppermint oil is said to reduce the intensity of headaches, though topical application may more effectively support this purpose. A study conducted by the Christian-Albrechts-Universität in Germany determined that "10 percent peppermint oil in ethanol solution efficiently alleviates tension-type headache."

Potential

Peppermint shows promise in reducing symptoms of depression, menstrual cramps, and gallstones. Further research is necessary before conclusions can be drawn.

Warning

Avoid peppermint if suffering from chronic heartburn or gastroesophageal reflux disease. Drug interactions with cyclosporine and antacids have been reported.

Considerations

Make sure to purchase only enteric-coated peppermint capsules. Enteric coating permits the oil to travel safely into the stomach without suffering damage from stomach acids.
