Rating (out of 5): 1

Pennyroyal (Mentha pulegium) has a long history of traditional use for alleviating menstrual cramps and promoting menstruation. Historical records from European folk medicine, as well as references in early American herbal texts, cite pennyroyal as an "emmenagogue"—an agent said to stimulate menstrual flow. Its use in this context is largely attributed to its volatile oils, particularly pulegone, which was believed to influence uterine contractions. However, these practices were based on anecdotal observations rather than controlled scientific studies.

There is little to no modern clinical evidence supporting pennyroyal's efficacy for menstrual cramps. In fact, most contemporary medical literature cautions against the use of pennyroyal due to its potential toxicity, especially when consumed as an essential oil. Pulegone, the major active constituent, is hepatotoxic and neurotoxic at relatively low doses. Thus, while the traditional use is well documented, there is no scientific validation for its safety or effectiveness in treating menstrual cramps. The overall evidence supporting its use is very weak, and health authorities strongly discourage its internal use due to safety concerns.
