Umckaloabo- coumarins from the root, traditionally used to treat bronchitis in children, have anti-bacterial and anti-viral properties.

A South African native medicine traditionally made from the tubers of Pelargonium sidoides +/- P. reniforme , said to have anti-diarrhoeal affects but principally used for acute bronchitis, coughs and colds. It is widely marketed in Europe for the respiratory indications. A Cochrane review found some evidence of efficacy but the quality of evidence was low to very low (Timmer A et al, Cochrane Database of Systematic Reviews 2013; 10: CD006323) A Major Stevens who had been in S.Africa set up a company in 1907 in Wimbledon producing ‘Stevens’ cure for tuberculosis’ – Umckaloabo. He wrote several books promoting this and was the subject of numerous court cases. His cause was taken up by a Swiss physician, Dr Adrien Sechehaye, who continued to publish positive clinical papers on the medicine until the 1930s. The ‘cure’ was debunked by the BMA in one of their reports on quack medicines – ‘Secret Remedies – and what they contain’.

Stevens’ Cure (Umckaloabo)—the vindication of a patent medicine. T. Brendler1, M. A. Stander, and B.-E. van Wyk Stevens’ Cure (Umckaloabo) emerged as a patent medicine claiming to treat tuberculosis in the United Kingdom at the beginning of the 20th century. However, due to its identity being shrouded in secrecy, it was never truly accepted by the medical community. It was “rediscovered” in the 1970s and subsequently developed into a very popular and successful phytopharmaceutical for the treatment of upper respiratory tract infections.
