Chemical Composition and Biological Activities of Diverse Products from Commiphora gileadensis: A Comparative Review

Background/Objectives:Commiphora gileadensis (Balm of Gilead) is an aromatic medicinal plant with a history of traditional use in ancient and Arabic medicine. It has been used traditionally to treat inflammation, infections, and wounds. Despite its long-standing cultural and economic importance, modern pharmacological validation requires a comprehensive synthesis of current scientific data. This review aims to provide a thorough comparative summary of the phytochemical composition and biological activities of its diverse products. Methods: An updated literature search was conducted using databases such as ScienceDirect, PubMed, Scopus, and Google Scholar, covering publications from approximately 2000 to 2025. The review included English-language peer-reviewed articles, books, and reports providing phytochemical analyses or biological evaluations. Data were manually extracted and categorized by plant parts (resin, leaves, bark, stems), major constituents, and specific pharmacological activities. Results: The review identified ten diverse chemical groups, mainly terpenoids (mono-, sesqui-, di-, and triterpenes) and flavonoids. Other remarkable classes included phenolic acids, phytosterols, lignans, coumarins, and fatty acids. However, the essential oil chemical profile is highly variable, influenced by geographical origin and preparation technique. Pharmacological studies demonstrated a wide spectrum of bioactivities, in particular antioxidant, anti-inflammatory, antimicrobial, anticancer, antidiabetic, and wound-healing properties. Toxicological studies classified the plant as generally non-toxic; however, there is a notable lack of clinical and pharmacokinetic data. Conclusions:C. gileadensis possesses a rich and diverse secondary metabolite profile, validating its traditional ethnobotanical applications. Future research should prioritize pre-clinical and clinical trials to establish its safety, bioavailability, and metabolic fate for its successful integration into modern medicine.
