Concentrations of selected elements in C. obliquus bulbs collected from eight market sites around the KwaZulu-Natal province were investigated.

Imbiza is a herbal tonic, which has gained popularity amongst South Africans as an immune booster and for the treatment of many minor and chronic illnesses. Main ingredients of Imbiza are extracts from two medicinal plants namely Cyrtanthus obliquus and Lippia javanica. The concentrations of various elements in these two plants are examined. The total and water extractable elemental concentrations were determined in both the plants. The elemental concentrations in the water extracts more closely represent concentrations in the herbal tonic.
