Synopsis

Source of validity: Traditional
Rating (out of 5): 1

Ruta graveolens (commonly known as Rue) has a long history of use in traditional herbal medicine, including as a remedy for lice infestations. Historical records from various cultures, especially in Europe and the Mediterranean, show that Rue was used as an insect repellent and sometimes applied topically in concoctions or infusions to treat head lice. The rationale behind its use likely stems from its strong, pungent aroma and the presence of phytochemicals such as alkaloids and essential oils that may have some insect-repellent properties.

However, there is no robust scientific evidence or clinical trials supporting the efficacy or safety of Rue for treating lice. Modern research does not confirm any direct pediculicidal (lice-killing) effects of Rue extract or oil. Most available references to its use are anecdotal or found in ethnobotanical surveys rather than peer-reviewed scientific literature. Furthermore, Rue contains compounds that can be irritating or even toxic to the skin, especially in high concentrations.

In summary, while Rue's use against lice is justified by historical and traditional practices, there is minimal scientific evidence to support its effectiveness. The evidence rating is low primarily because of the lack of controlled studies and the potential safety concerns associated with topical application.
