Investigators from Walter Sisulu University, South Africa, evaluated antibacterial and anticancer activity of six medicinal plants used in the treatment of diarrhea stomach disorders: Eucomis autumnalis (autumn pineapple flower, autumn pineapple lily), Cyathula uncinulata (bohome, burweed, globe cyathula, klits, maime, rondeklits, tchimate, wolbossie), Hypoxis latifolia (broad-leaved hypoxis, igudu, ilabatheka, ilabetheka, ingcobo, inkomfe, yellow star), Lantana camara (Spanish flag, West Indian lantana, LAVA), Aloe arborescens (Krantz aloe, candelabra aloe) and Aloe striatula (hardy aloe, coral aloe).

The results indicated that E. autumnalis had a profound cytotoxic effect, and the investigators called for caution in its use. However, they found that the antibacterial activities and non-cytotoxic effects of A. arborescens and A. striatula validates their continuous usage in ethnomedicine.
