Clinical Applications Of Peppermint:

Most of peppermints uses revolve around its essential oil. Whether as a flavouring agent, refrigerant, antinflammatory, or muscle relaxant, peppermint is almost never used alone.

Liquid extracts are often used in formulations to provide a cooling sensation in the stomach and is used to relvieve flatulence and bloating alongside bitter herbs.
