Folk medicinal uses

This well-known drug plant is used to some extent in Jamaica for asthma and sinus infections. 'It palliates the distressing paroxysms of pure spasmodic asthma when smoked'. (Lindley). The leaves are rubbed up and applied externally to swellings, burns and ulcers. Similar uses are made of the plant in South Africa. The leaves are also used for headaches, haemorrhoids and running sores. Browne reports that in his day the plant was seldom used internally as its use was accompanied by 'dreadful perturbations of the mind', though it was tben used for scalds and sores.
