What Is Pennyroyal?

Pennyroyal is an herb that is a member of the mint family. It has a distinctive taste and odor that is more pungent than other varieties of mint, making it disagreeable to insects and to some humans. The use of pennyroyal as an herbal medicine is controversial. Pennyroyal can be toxic when consumed in large doses, and skin contact with the pure oil can cause dermatitis. Pulegone, which is a compound found in pennyroyal and is responsible for the negative effects it can have, is highly soluble in oil and much less soluble in water.
