CLINICAL RESPIRATORY CPD MEDICINAL USE OF PELARGONIUM SIDOIDES Pelargonium sidoides is an important traditional medicine with a rich ethnobotanical history. The importance of Pelargonium species, most notably Pelargonium reniforme and Pelargonium sidoides, in traditional medicine in the southern African region is well documented. A modern aqueous- ethanolic formulation of the roots of P. sidoides (EPs 7630) is successfully employed for the treatment of ear, nose and throat disorders as well as respiratory tract infections. To provide a scientific basis of its present utilisation in phytomedicine, EPs 7630, extracts were evaluated for antibacterial activity and for their effects on nonspecific immune functions. The samples exhibited merely moderate direct antibacterial capabilities against a spectrum of Gram-positive and Gram-negative bacteria. Functional bioassays including an in vitro model for intracellular diseases, a fibroblast lysis assay (tumour necrosis factor [TNF] activity), a fibroblast-virus protection assay (IFN activity) and a biochem
