Funtumia elastica

Funtumia elastica (silkrubber [1]) is a medium-sized African rubber tree with glossy leaves, milky sap, and long woody seedpods. The bark is used in the traditional medicine of tropical Africa.[citation needed]

Chemical constituents[edit]

A variety of chemical compounds have been identified in F. elastica. Unprocessed F. elastica powder is distinctly blue due to its anthocyanin content.[citation needed] The steroidal alkaloid conessine, which is found in F. elastica, has anti-bacterial properties in vitro.[2]


Crude extracts of F. elastica inhibit growth of many molds, including Aspergillus, Penicillium, and Candida, as well as the fungi that cause ringworm.[3]
