In the UK Bing Lang must be substituted. Zhi Shi and either Yu Li Ren or Fei Zi for parasites are the standard substitutions. Alternatively if being used for malarial disorders as many discussions of the Membrane Source imply then Qing Hao may be suitable although the fresh herb is really needed if the antimalarial component Artemisinin is wanted.

The Membrane Source (Mo Yuan) is a concept whose exact definition has changed over time but which generally seems to relate the membranes surrounding the vital organs and especially the diaphragm. As such it associated with the San Jiao and with Shaoyang as half interior, half exterior.
