Peppermint (Mentha x piperita) is a plant in the mint family. It’s a natural hybrid of spearmint and wild mint. The leaf and oil are used as medicine.

People use peppermint for irritable bowel syndrome (IBS). It is also used for indigestion, bed sores, tension headache, anxiety, insomnia, memory, and many other purposes, but there is no good scientific evidence to support many of these uses.
