Pennyroyal is the smallest of the mint family, and has some very distinctive properties. The taste and odor of pennyroyal is stronger and far more pungent than other mints, which makes it disagreeable to many people. It's also disagreeable to insects, and pennyroyal has been used as a natural insect repellant for centuries. Like the other mints, it helps soothe digestion and may reduce muscle spasms.*
