Peppermint tea is reported to relieve headaches, alleviate anxiety that is related to depression, soothe symptoms of the common cold, treat indigestion and nausea, and help resolve menstrual problems. However, more evidence is needed, says WebMD.
When it comes to gastrointestinal conditions, peppermint acts by calming the stomach muscles. This improves the flow of bile, which aids in fat digestion. Food is thereby processed and carried through the stomach more rapidly, explains the University of Maryland Medical Center.
While several studies have shown that the use of enteric-coated peppermint capsules does support its efficacy for treating irritable bowel syndrome and indigestion, no human clinical trials on the benefits of peppermint tea leaves have been done, according to PubMed.
Peppermint tea is brewed from the dried leaves of the peppermint plant. To prepare the tea, 1 teaspoon of dried leaves should be steeped in 1 cup of boiling water for 10 minutes. The liquid should then be strained and cooled. It is advised to drink the tea four to five times a day between meals, according to the University of Maryland Medical Center.
Peppermint tea is not advised for anyone who suffers from gastroesophageal reflux disease because it may relax the sphincter between the esophagus and the stomach. This allows acids to rise up the esophagus, worsening symptoms of indigestion and heartburn, explains the University of Maryland Medical Center.
