Abstract

Oregano [Origanum compactum Benth. (O. compactum), Lamiaceae] is an endemic Moroccan medicinal herb. It is used traditionally to fight against several disorders such as diarrhea, urolithiasis, hypertension, diabetes, and inflammation. A large number of components have been identified and isolated from the essential oil of this plant. Carvacrol, thymol, p-cymene and γ-Terpinene are among the more compounds presented in O. compactum essential oil and considered to be the main biologically active components. Numerous experimental studies showed that O. compactum organic extracts, essentials oil and its main compounds possess a broader spectrum of pharmacological and therapeutic activities such as antibacterial, antifungal, antioxidant, and anticancer activity. The present review attempts to give an overview of pharmacological studies of O. compactum and its major compounds.
