The African wintersweet (Acokanthera oblongifolia) belongs to Apocynaceae (the Dogbane family). It is a small evergreen tree that is distributed from Mozambique to South Africa. It grows in deserts, dry shrub zones, and coastal thickets, and can reach a height of around 6 m. The leaves are elliptic or oblong, green, pointed at the end, and have a short petiole. In spring, it produces an inflorescence from the leaf axils, and white to pale pink tubular flowers bloom. The flowers have a pleasant fragrance. The fruit turns purple when ripe. Both the sap and the fruit are poisonous. This species has been used to treat snake bites, as an anti-itch medicine, to kill parasites in the body, and as an arrow poison.
