Cedarwood essential oil (Cedrus spp.): a forgotten pharmacological resource with emerging therapeutic potential

Cedarwood essential oil (CWO), obtained from Cedrus and related species, has a long history in traditional medicine but remains relatively underexplored in modern pharmacology. This review consolidates current evidence on its phytochemical composition and pharmacological activities. Literature was retrieved from PubMed, Web of Science, and Scopus up to July 2025, including in vitro, in vivo, and limited clinical studies. Findings suggest antimicrobial, anti-inflammatory, sedative, and dermatological properties, primarily attributed to sesquiterpenes such as cedrol and α-cedrene. However, most data derive from small-scale or preclinical studies, with limited standardization of dosage and formulations. Safety aspects and toxicological gaps are also highlighted as essential considerations for future clinical translation. We conclude that CWO shows therapeutic potential, but rigorous clinical trials, standardized protocols, and comprehensive toxicological evaluations are essential before its safe and effective integration into evidence-based practice.
