Ageratum conyzoides (billygoat-weed, chick weed, goatweed, whiteweed, mentrasto) is native to Tropical America, especially Brazil , and is an invasive weed in many other regions. It is an herb that is 0.5–1 m. high, with ovate leaves 2–6 cm long, and flowers are white to mauve.[3]
In Vietnamese, the plant is called cứt lợn (meaning "pig feces") due to its growth in dirty areas.[4]
Uses
As a medicinal plant, Ageratum conyzoides is widely used by many traditional cultures, against dysentery and diarrhea.[5] It is also an insecticide and nematicide.[6][5]
Toxicity
Ingesting A. conyzoides can cause liver lesions and tumors.[7][8] There was a mass poisoning incident in Ethiopia as a result of contamination of grain with A. conyzoides.[9] The plant contains the pyrrolizidine alkaloids lycopsamine and echinatine.
Weed risk
A. conyzoides is prone to becoming a rampant environmental weed when grown outside of its natural range. It is an invasive weed in Africa, Australia, Southeast Asia, Hawaii, and the USA.[10][11] It is considered a moderate weed of rice cultivation in Asia.[12]
