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  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.
