TLDR Rosemary essential oil can improve mood, sleep, and cognitive function but may cause allergies, so use it carefully.

The review systematically evaluates rosemary essential oil's therapeutic potential in aromatherapy, focusing on cognitive enhancement, mood improvement, pain management, and treatment for androgenetic alopecia. It includes 39 studies, highlighting the oil's effectiveness in applications like inhalation and massage for anxiety, sleep quality, and pain relief. Key compounds such as 1,8-cineole, camphor, and α-pinene contribute to its benefits. However, potential adverse effects, including allergic reactions and contact dermatitis, are noted, stressing the need for cautious use and proper dilution. The review calls for standardized oils and evidence-based guidelines to ensure safe and effective practices.
