About

Euphorbia candelabrum is a succulent species of plant in the family Euphorbiaceae, one of several plants commonly known as candelabra tree. It is endemic to the Horn of Africa and eastern Africa along the East African Rift system. It is known in Ethiopia by its Amharic name, qwolqwal, or its Oromo name, adaamii. It is closely related to three other species of Euphorbia: Euphorbia ingens in the dry regions of southern Africa, Euphorbia conspicua from western Angola, and Euphorbia abyssinica, which is native to countries including Sudan, Eritrea, Djibouti, Ethiopia and Somalia.

Its Latin name derives from its growth habit, often considered to resemble the branching of a candelabrum. Candelabra trees can be found in dry deciduous and evergreen open wooded grasslands, on rocky slopes and on rare occasions termite mounds. As rainfall decreases, so does E. candelabrum's habitat range.

Uses

Although Euphorbia candelabrum is known to be quite toxic, it has seen medicinal use. Its latex contains highly irritant ingenol diterpene esters, which prove to be both harmful and helpful. On top of blistering and irritation, ingenol products demonstrate tumour-promoting activity, causing cells to resist apoptosis and continue multiplying. A 1961 study found that latex from various Euphorbia species, including E. candelabrum, is a potent tumor-promoting agent. However, ingenol has been reported to encourage anti-HIV and anti-leukemia cellular activity that protects T-cells.
