Pennyroyal Essential Oil

Pennyroyal Essential Oil comes from the extracted leaves of the plant Penny Royal (Mentha pulegium). It lives by its genus Mentha because it literally smells minty. Pennyroyal is also called Coyote Mint, Dwarf Thyme, or Wild Bergamot in some places.

The extraction of the plant’s flowering parts and leaves is carried on through steam distillation. In this process, main chemical constituents are drawn out such as menthone, neo menthone, iso menthone, and pulegone. Although Pennyroyal Essential Oil has a lot of health benefits to offer, it is filled with high pulegone content which makes it poisonous. The toxicity is due to the pulegone that metabolizes into methanofuran. Menthofuran is considered as a liver toxin that causes death. However, if it is handled well with appropriate dosage, the oil can save lives.

Pennyroyal Essential Oil is commonly used in the fragrance trade for its earthy mint odor. It partially blends with other herbal plants such as citronella, lavender, sage, rosemary, and germanium. Contradictory to its toxicity, some people use it as a food flavoring. Studies show negative effects in the body and internal use is highly discouraged. In addition, the oil is not allowed to be applied directly on skin unless it is diluted.
