The plant is harvested from the wild for use as a dye.
This species has a fairly large range of over 30,000 km², but its population has declined in the past. It has become harder to find in the field and it is likely that the species has been lost from some localities. The main threat to the species is habitat degradation as a result of human activities, and the wild population is likely to continue declining in the future. It is impossible to determine the extent of the population reduction, but the plant is probably close to qualifying as threatened. It is currently classified as 'Near Threatened' in the IUCN Red List of Threatened Species(2013)[

Known Hazards

The sap of Aloe species contains anthraquinones. These compounds have several beneficial medicinal actions, particularly as a laxative, and many species of Aloe are thus employed in traditional medicine. Whilst safe in small doses and for short periods of time, anthraquinones do have potential problems if used in excess. These include congestion and irritation of the pelvic organs[

Cultivation Details



Aloe species follow the Crassulacean acid metabolism (CAM). CAM plants can fix carbon dioxide at night and photosynthesize with closed stomata during the day, thus minimizing water loss. This, plus their succulent leaves and stems, and the presence of a thick cuticle, makes them well adapted to dry conditions[
