I had been naming this plant as Artemisia scoparia (Redstem Wormwood) until June 2015 when I saw an article on the local newspaper by Wilson Wong. Ironically, Artemisia scoparia may contain compounds that protect the liver [1] while Eupatorium capillifolium contains pyrrolizidine alkaloids that may cause liver damage when consume in large quantity for prolong period. Therefore, mixed up of the 2 plants may have detrimental effect if one is consuming it regularly.
