A plant species used in traditional medicine and as a source of arrow poison
Overview[edit]
Strophanthus kombe is a species of flowering plant in the family Apocynaceae. It is native to tropical regions of Africa, where it is found in countries such as Tanzania, Mozambique, and Malawi. The plant is known for its medicinal properties and its use as a source of arrow poison.
Description[edit]
Strophanthus kombe is a climbing shrub or liana that can grow up to 10 meters in length. The leaves are opposite, simple, and elliptical, with a glossy green appearance. The flowers are tubular and fragrant, with a distinctive star-like shape, and are typically white or pale yellow with purple streaks.
