Uses
editAs 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
editIngesting 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
editA. 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]
