Mikania micrantha is a tropical plant in the Asteraceae; known as Bitter Vine or Climbing Hemp Vine or American Rope. It is also sometimes called Mile-a-Minute Vine (a moniker usually reserved for the unrelated Persicaria perfoliata, an invasive pest).
It is a vigorously growing perennial creeper that grows best in areas in high humidity, light and soil fertility, though it can adapt in less fertile soils. The featherlike seeds are dispersed by wind. A single stalk can produce between 20 and 40 thousand seeds a season.
The species is native to the sub-tropical zones of North, Central, and South America.
Mikania micrantha is a widespread weed in the tropics. It grows very quickly (as fast as 80 to 90 mm in 24 hours for a young plant) and covers other plants, shrubs and even trees.Mikania is a problem in Nepal, covering more than 20% of the Chitwan National Park.
It is used to heal cuts and stop minor external bleeding in Fiji but its medicinal properties are still yet to be fully discovered. It is also a very popular local antiseptic medicine in Mizoram State of India, it is known locally as Japan Hlo.
