Ageratum conyzoides

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 cứt lợn (Pig Feces) due to its growth in dirty areas.[2]



It has medicinal plant properties. However, it's limited for internal use due to toxicity issues. It is also an insecticide and nematicide.[3]


Ingesting A. conyzoides can cause liver lesions and tumors.[4][5] The plant contains the pyrrolizidine alkaloids lycopsamine and echinatine.[6]

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]
