Do not take peppermint or drink peppermint tea if you have gastroesophageal reflux disease (GERD - a condition where stomach acids back up into the esophagus) or hiatal hernia. Peppermint can relax the sphincter between the stomach and esophagus, allowing stomach acids to flow back into the esophagus. (The sphincter is the muscle that separates the esophagus from the stomach.)
By relaxing the sphincter, peppermint may actually make the symptoms of heartburn and indigestion worse.
