Scoparia dulcis

Scoparia dulcis is a species of flowering plant in the plantain family. Common names include licorice weed, goatweed, scoparia-weed and sweet-broom in English, tapeiçava, tapixaba, and vassourinha in Portuguese, escobillo in Spanish, and tipychä kuratu in Guarani. It is native to the Neotropics but it can be found throughout the tropical and subtropical world. Although S. dulcis is considered a weed in many parts of India and Bangladesh, its use in traditional medicine has led to overexploitation. The plant is also found as a weed in American citrus groves....read more on Wikipedia.
