Peppermint - Research
Pharmacological studies have been conducted to evaluate peppermint’s possible effects on various gastrointestinal and neurological conditions such as dyspepsia and tension headaches.3 New clinical trials are evaluating peppermint as an aromatherapy agent for relieving nausea.7 Peppermint’s antispasmodic and antidiarrheal effects are topics of continued research.8
The plant has been used medicinally as a tonic for preventing gas and relieving spasms, and other stomach ailments.5 It also has been used to assist in alleviating tension headaches.3 Today, the peppermint plant is commonly added to cough and cold remedies because of its high menthol content, which provides a sensation of coolness and easier breathing.6
