Safety & 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[1]. Long term use of anthraquinone laxatives may also play a role in development of colorectal cancer as they have genotoxic potential, and tumorigenic potential[1].

Cultivation Details

HabitEvergreen Perennial
Growth—

The plant is reported to hybridize in the wild with Aloe secundiflora[2]. 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[1].

Propagation

Seed - we have no specific information on this species - in general Aloes are sown in a sandy, well-drained potting soil in a warm, shady position in standard seed trays. Germination takes about three weeks. Cover the seed with a thin layer of sand (1 - 2mm), keep moist. The seedlings can be planted out in individual bags or containers as soon as they are large enough to handle[3].
