Pennyroyal essential oil is extracted from a grass-like herb called Mentha Pulegium, a plant that belongs to the mint family. The leaves of this plant smell reminiscent of mint and its flowers have a purple tint to them. Do not be fooled by its harmless smell and appearance! This oil is a deadly poison due to its high pulegone content. It is indeed quite questionable why pennyroyal was used in folk remedy. However, it is also true that many of our medicines are based on natural poisons.

The earliest documented use of pennyroyal dates back to the ancient Greeks, Romans and Medieval cultures, where the herb was commonly incorporated into food. The Romans also used pennyroyal as a form of contraceptive for women and was used to perform abortions. Due to its highly potent poison, pennywise has also been used extensively as insecticides and to eradicate pests.
