Damakase (<i>Ocimum lamiifolum</i> Hochest ex Benth): A Medicinal Plant Used in Ethiopian Traditional Medicine: A Critical Review

Abstract

Damakase (<i>Ocimum lamiifolum </i>Hochest ex Benth) is a traditional medicinal plant belonging to the Lamiaceae family and a popular home remedy in Ethiopia. It is a well-known and widely used ancient therapeutic herb in various regions of the nation. The utilization of plant leaves for medicinal purposes is primarily due to their rich content of bioactive compounds with therapeutic properties. Consequently, this plant is employed in the management of a condition referred to as 'Mich' in Ethiopia. Additionally, it is frequently used to address diverse health conditions, including gastrointestinal disorders, inflammatory conditions, pyrexia, and respiratory ailments. Moreover, the essential oil derived from Ocimum lamiifolium consists of specific chemical constituents, such as alkaloids, sterols, carbohydrates, glycosides, tannins, flavonoids, bornyl acetate, p-cymene, camphene, α-pinene, and sabinene. Bioactive constituents, such as phenolics, flavonoids, and terpenoids, exhibit antibacterial, antioxidant, and anti-inflammatory properties. Furthermore, the potential applications of damakase essential oils as natural preservatives in the food and cosmetic sectors have been recognized. The essential oil is deemed safe and non-hazardous, displaying no mutagenic or cytotoxic effects. Despite the extensive historical use of this traditional medicinal plant in Ethiopia, the limited scientific investigations on its genetic improvement, cultivation practices, and integration into modern healthcare pose a notable challenge. This review aims to furnish a comprehensive discourse on the historical and contemporary applications of traditional damakase in Ethiopian traditional medicine.
