General Information

Aloe nyeriensis is a succulent, evergreen shrub with erect stems that branch at or near the base; it can grow from 1 - 3 metres tall. Each stem is topped by a rosette of leaves.
It is sometimes grown as an ornamental.

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

Cultivation Details

A plant of drier areas in the tropics. Plants are not frost tolerant[].
Succeeds in full sun and in light shade[]. Established plants are drought resistant[].
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[].

Edible Uses

None known

Medicinal

The leaf sap is used locally by women to clear up pimples and blemishes on the face[].

The leaf exudate contains aloin A (barbaloin) and homonataloin[].

The distinctive constituents in Aloe leaves are phenolic compounds, including chromone, anthraquinone or anthrone derivatives. Some of the compounds are found in many species, whereas others occur in only a few[].

Other Uses

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[].
