Genus Curtisia is a type of tree found in southern Africa that is known for its medicinal properties. It has several synonyms such as Curtisia dentata, Aspidosperma curtisiae, and Ochrosia curtisiae. The tree is commonly referred to as the Cape Lancewood due to its lance-shaped leaves. The bark of the tree was traditionally used by indigenous African tribes to relieve fever, stomach ailments and rheumatism.
