This herb is prohibited from use in the UK under the banned and restricted herbal ingredients list issued by the MHRA because it can also refer to Aristolochia manshuriensis (Guan Mu Tong) which contains toxic aristolochic acid. In some European countries with statutory testing of imports the species can be identified but the UK has chosen to ban all species to avoid regulation. It is generally substituted with Qu Mai or Tong Cao.
