MENISPERMACEAE(Moonseed family)
350 species in 65 genera are found in warm regions. A few species are medicinal on account of a bitter principle in the root. [Summary yet to be added] The fruits are used as a fish-poison. Cavities in the plants are inhabited by mites (acarodomatia). Application of a preparation of the plant to the scalp reportedly produced a scarlet eruption on the body and arms (Piffard 1881). Waring (1883) noted that in India, the seeds, beaten into a paste then incorporated into lard, kokum butter or ghee, have been used to destroy pediculi. He cautioned that care has to be taken to avoid abraded or ulcerated skin on account of the danger of absorption of the poisonous principle. The alkaloids of the wood may be injurious to wood-workers (Pernet 1957, Hausen 1970). The wood of this Sri Lankan tree may be injurious to woodworkers from a content of berberine (Hausen 1973). Reactions to berberine are noted under Berberis (fam. Berberidaceae). In Ceylon a dye and a bitter tonic are extracted from the wood. Vorreiter (1958) lists it as a toxic wood causing vomiting, diarrhoea and cramps. The plant is only a climber and produces no timber (Gamble 1902). Three species are found in temperate eastern Asia, Atlantic North America and Mexico.
The root of this plant like that of sarsaparilla (Smilax spp., fam. Smilacaceae) has been used in folk medicine for skin diseases (Wren 1975). The rough sharp ridges of the fruit pips can cause mechanical injury (Der Marderosian 1966). The root shavings from this tropical West African plant, when put on wounds, produce a burning sensation (Irvine 1961). The roots are acid in the mouth but cause things eaten thereafter to taste sweet (Dalziel 1937; Menninger 1967). This property is also noted with Synsepalum dulcificum Daniell (fam. Sapotaceae) and Thaumatococcus daniellii Benth. (fam. Marantaceae). The genus Sphenocentrum is monotypic. it is found in tropical West Africa. The common name of this vine, which is found in Western Australia, might cause it to be confused with Toxicodendron radicans Kuntze (fam. Anacardiaceae). References
