A member of the mint family, pennyroyal (Mentha pulegium) is a low-growing herb that features its famously furry oval leaves and clusters of soft purple flowers. This minty-fresh smelling perennial has been used by humans for centuries, stemming from its popularity as a pest repellant--hence its name, which is derived from the Latin word for "flea."

History of Pennyroyal
For centuries, pennyroyal has been renown for its abilities as a flea and pest repellant--in fact, it's a popular addition to gardens for keeping away unwanted insects from plants! The idea of using pennyroyal this way is said to come from Pliny the Elder, who used it as a powerful deterrant against fleas. It was once used in cooking, though it has since been recommended to avoid ingesting pennyroyal due to its toxicity. Pennyroyal oil should be avoided altogether if you are pregnant.

Sprinkle 5-10 drops into shower steam before getting in for an at-home spa experience.
8-10 drops of essential oil per 1 ounce of carrier oil. Apply a small amount directly to areas of concern, such as muscles, skin, or joints. Work the oil gently into the skin until it is fully absorbed.
Inhale the aromatic vapors directly from the bottle, or place a few drops in a burner or diffuser to fill a room with its scent.
