Medicinal

Pergularia daemia is a popular traditional medicine in Africa where numerous uses have been reported for all parts of the plant throughout its distribution area. Modern research has shown the presence of a wide range of medically active compounds, especially glycosides. The plant is also toxic causing an immediate and sustained rise of carotid blood pressure when taken in excess. Complex effects on the respiratory system and intestinal movements are also present combined with a generally cardiotoxic effect upon the heart with marked depression of both auricles and ventricles, resulting in ventricular fibrillation and ultimate stoppage of the heart in diastole[
