ABSTRACT
Twenty-four hour ip median lethal doses (LD50) of freeze-dried aqueous extracts of Heliotropium scottae Rendle leaves and stems in mice were determined and clinical signs noted. The LD50 of the leaf extract was 3.0 g/kg, while that of the stems was 3.5 g/kg. Clinical signs were excitement, prostration, rapid breathing, gasping for breath and death. The signs were the same for both the leaf and stem extracts. It was concluded that both the leaves and stems of H scottae have slight acute toxicity.
