Abstract
Among the Pelargonium-based herbal remedies that are widely used in traditional medical systems in the Southern African region is a highly valued root medicine (commonly termed umckaloabo) of initially unknown botanical origin for the treatment of infectious conditions of the respiratory tract including tuberculosis. Nowadays, a modern aqueous-ethanolic formulation of the roots of Pelargonium sidoides (EPs® 7630), developed from this traditional medicine, is successfully employed for the treatment of bronchitis. The article summarizes the fascinating story of this herbal medicine including its way to Europe, identification of the botanical origin, and provides background information of the many profound anti-infectious actions and clinical studies. In spite of considerable effort, the underlying chemical principle is still not clear.
Key words
