What is Pennyroyal?

Pennyroyal is a plant. The oil and leaves are used to make medicine. Throughout history, both American pennyroyal and European pennyroyal have been used interchangeably as a source of oil.

Despite serious safety concerns, pennyroyal is used for colds, pneumonia, and other breathing problems. It is also used for stomach pains, gas, intestinal disorders, and liver and gallbladder problems.

Women use it to start or regulate their menstrual periods, or to cause an abortion.

Pennyroyal is also used to control muscle spasms, cause sweating, and increase urine production.

Some people use it as a stimulant and to counteract weakness.

Pennyroyal is applied to the skin to kill germs, keep insects away, and treat skin diseases. It is also used topically for gout, venomous bites, and mouth sores; and as a flea-killing bath.

In foods, pennyroyal is used for flavoring.

In manufacturing, pennyroyal oil is used as a dog and cat flea repellent; and as a fragrance for detergents, perfumes, and soaps.
