A Mini Review of Medicinal Plants Effective Against Head Lice: A Traditional Medicine Approach to Skin and Hair Hygiene

Abstract

This study reviews the use of medicinal plants with antiparasitic properties for treating head lice (Pediculus humanus capitis), a common health concern, particularly among children and in densely populated settings. It underscores the importance of traditional medicine in utilizing these plants as a natural and effective approach to maintaining skin and hair hygiene. The review examines the mechanisms of action of these medicinal plants in promoting overall skin and hair health. To conduct the study, keywords such as "medicinal plants," "Iran," "head lice," and "traditional medicine" were used for literature searches across databases including Google Scholar, SID, Magiran, PubMed, and Scopus, as well as traditional medicine texts and online resources. The findings indicate that 24 native medicinal plant species in Iran are traditionally used for controlling head lice. The analysis reveals that medicinal plants used against head lice predominantly belong to the Lamiaceae, Myrtaceae, and Arecaceae families. Decoction is the most common preparation method (50%), with leaves being the most frequently used plant part (54.55%). These findings highlight the significance of leaf-based remedies and decoction in traditional medicine for head lice treatment. Traditional Iranian medicine, with its emphasis on natural remedies, offers promising treatment options with minimal adverse effects.
