Abstract

OBJECTIVES:

Aloe species have been noted to be a miracle cure used by indigenous people of southern Africa. Geographically, each of the three Aloe species-Aloe arborescens, Aloe excelsa, and Aloe ferox-has a specific habitat. Although some species overlap in geographical regions, the species most abundant in a region is most often utilized by indigenous people. All three species display similar curative properties, aiding in wound healing, cures against other skin ailments, and some systemic conditions.

RESULTS:

All three Aloe species indicated high inhibitory activity against all gram-positive bacteria under investigation. The ethanol extract was most effective and inhibited all gram-positive bacteria and two gram-negative bacteria (i.e., Proteus vulgaris and Escherichia coli).

CONCLUSIONS:

All fungal species under investigation were successfully inhibited by both the boiled water as well as the ethanol extract, substantiating the traditional usage of this species.
