The genus Aloe is widely used for medicinal purposes throughout its predominantly African distribution, but detailed knowledge of the contemporary value of aloes is patchy. The main aim of this study was to determine the value of Aloe in the Highlands of Ethiopia, a region of rich Aloe diversity, by documenting local uses and perceptions of the sustainability of the species used. Amhara and Tigray community members participated in semi-structured interviews from 110 respondents aged 24-72. Eleven species of Aloe were recorded for medicine, social and environmental uses, animal food, and as bee plants managed for honey production. Of these, the majority of use records were for human medicine to treat malaria and wounds. We found no evidence of non-sustainable harvesting for medicine, but extensive habitat loss and interest in the commercial uses of Aloe present acute threats and indicate the vulnerability of Aloe species in the central and northern Highlands of Ethiopia.
