Paederia foetida is a species of plant, with common names that are variations of skunkvine, stinkvine, or Chinese fever vine. It is native to temperate, and tropical Asia; and has become naturalized in the Mascarenes, Melanesia, Polynesia, and the Hawaiian Islands, also found in North America by recent studies.
Paederia foetida is known for the strong, sulphurous odour exuded when its leaves or stems are crushed or bruised. This is because the oil responsible for the smell, and found primarily within the leaves, contains sulphur compounds, including largely dimethyl disulphide
HISTORICAL AND MYTHOLOGICAL REVIEW:
he native range of skunk vine was determined by Puff (1991b) and by Pemberton, who examined ca. 400 skunk vine specimens in the herbaria of the National Museum of France (Paris), the Royal Botanical Garden at Kew (UK), the British Museum of Natural History (London), and the Makino Herbarium at Tokyo Metropolitan University (Japan). The plant reaches north as far as 42º at the tip of the island of Honshu in Japan. Its southern limits are Christmas Island (south of Java) and Timor in Indonesia – both at about 10ºS. To the east the plant reaches Honshu and Japan’s Bonin Islands at about 143ºE, to the west skunk vine reaches Nepal at about 85ºE.
Paederia foetida was reportedly introduced as a potential fiber plant to an unknown location in Florida by the U.S. Department of Agriculture prior to 1867 (Morton, 1976). The geographic origin of the introduced material is unknown. This plant was identified as a problematic weed as early as 1916, when it was found to have entangled ornamental plants near the city of Brooksville (Hernando County) in central western Florida (USDA, 1918). Early references to skunk vine in the region, coupled with its current geographic distribution (Fig. 2), suggest the site of original introduction and epicenter for subsequent dispersal was westcentral Florida (USDA, 1918; Small, 1933; Morton, 1976). Subsequent introductions from Darjeeling, India were made to the USDA Miami Plant Introduction Station in 1932 but the fate of these plants is unknown, as is the rationale for the introduction.
Gandha Prasarini (Paederia foetida) is an important Ayurvedic medicinal herb. The word meaning of Gandha Prasarini in Sanskrit is – it spreads bad smell Its different parts are used in different Ayurvedic Preparations. Its leaves are used against herpes infection, roots are used for relieving pain in the chest or liver, inflammation of spleen and also used as emetic.
The crop can be grown under the hot and humid climatic conditions, where average relative humidity is high (85%) and maximum & minimum temperature varies between 16°C and 30°C respectively and rainfall is 150-200 cm.
It is cultivated in plains to a higher altitude upto 600 m above msl. Soil should be sandy-loam and acidic in nature.
Vegetative propagation by cuttings.
Crop Maturity and Harvesting: Crop matures after six months. First harvest of vines can be done at 6 months (March-April) from the date after transplantation; thereafter, at 4 months interval (July-August and October-November). Winter harvesting is not advisable.
Plant contains friedelan-3-one, β-sitosterol and epifriedelinol; the leaves and stem gave iridoid glycosides – asperuloside, paederoside and scandoside; sitosterol, stigmasterol, campesterol; ursolic acid, hentriacontane, hentriacontanol, ceryl alcohol, palmitic acid and methyl mercaptan.

Introduced by the U.S. Department of Agriculture before 1897
as a potential fiber plant; by 1916 already “a troublesome weed” around the Brooksville
Field Station (Morton 1976). Noted as escaping to thickets and fence rows in peninsular
Florida by Small (1933). Considered an economically important weed by 1977 (Reed
1977). Occurs most often in tree gaps and other disturbed areas in its native range (Puff
1991). In Florida, invades various native plant communities, including sandhill, floodplain, and upland mixed forest.
