Ageratum conyzoides (Billygoat-weed, Chick weed, Goatweed, Whiteweed; Ageratum conycoides L., Ageratum obtusifolium Lam., Cacalia mentrasto Vell.) is native to Tropical America, especially Brazil. Herb 0.5 1 m. high, with ovate leaves 2 6 cm long, and flowers are white to mauve.[1] In Vietnamese, the plant is called c t l n (Pig Feces) due to its growth in dirty areas.[2]
Uses As a medicinal plant, Ageratum conyzoides has limited uses due to its toxicity. It is also an insecticide and nematicide.[3] Toxicity Ingesting A. conyzoides can cause liver lesions and tumors.[4][5] There was a mass poisoning incident in Ethiopia as a result of contamination of grain with A. conyzoides.[6] 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 and USA.[7][8] It is considered a moderate weed of rice cultivation in Asia. [9] References - ↑ NSW Flora Online, Ageratum conyzoides
