About
Zanthoxylum asiaticum is a species of plant in the family Rutaceae. Under its synonym Toddalia asiatica, it was the only species in the monotypic genus Toddalia, now included in Zanthoxylum. It is known by the English name orange climber.
Where it grows
It is native to many countries in Africa and Asia. Examples include South Africa where in Afrikaans it is called ranklemoentjie, and in Venda, gwambadzi. It is very popular among the Kikuyus of Central Kenya, where it is known as mururue, Mauritius, where it is known as patte poule or properly mũrũrũe.
Uses
The plant is used medicinally by many African peoples, including the Maasai, who use it for malaria, cough, and influenza. The roots contain coumarins that have antiplasmodial activity. Extracts of the plant have demonstrated antiviral activity against H1N1 influenza in the laboratory. The harvest of this slow-growing plant from the wild for medicinal use may cause its populations to decline.
