Growing EDIT
Distribution EDIT
Widely distributed in South Africa. Cultivation is illegal but the plant commonly grows as a weed along roadsides and in gardens and abandoned fields.
History EDIT
In South Africa, the plant was an early treatment for snake bite, malaria and blood poisoning. Cannabis was still included in the 1949 British Pharmaceutical Codex and tinctures and extracts have been used to a limited extent.
It is used in the treatment of glaucoma, to alleviate the nausea caused by chemotherapy and to stimulate appetite and a sense of well-being in AIDS patients.
It is also used in the treatment of asthma, depression and numerous other conditions.

The female flowering tops and associated leaves are smoked.
The dried resin produced by glands (mainly on the flowers of the female plant) is known as "hashish". This product can be smoked or eaten and has the most powerful effect.
