Plumbago auriculata Blume Plumbaginaceae Plumbago, Leadwort. Distribution: South Africa. It is used traditionally to treat warts, broken bones and wounds. It is taken as a snuff for headaches and as an emetic to dispel bad dreams. A stick of the plant is placed in the thatch of huts to ward off lightning.” Iwou (1993) reports other Plumbago species are used to cause skin blistering, treat leprosy, induce blistering, and to treat piles, parasites and to induce abortions. The genus name derives from the Latin for lead, but authors differ as to whether it was used as a treatment of lead poisoning, or that when it was used for eye conditions the skin turned the colour of lead.
