Ingredients
Hou Po 3g
Bing Lang 4.5g
Cao Guo 2.4g
Huang Qin 3g
Gan Cao 1.5g
Hou Xian Ye 3g
Zhi Basn Xia 6g
Sheng Jiang 3pc

Subsitutions:
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.



Preparation: Decoction.

Actions: Dispels and disperses turbid Dampness from the Membrane Source (Mo Yuan).

Contraindications: Due to the deficiency of the patient even greater care must be taken to stop taking once the obstruction is resolves and the Heat begins to discharge that with Da Yuan Yin.



Notes:
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.

This is for the same pattern as Da Yuan Yin but in a patient with Middle Jiao deficiency whose Yang Qi is therefore weak causing fewer signs of Heat such as fever, restlessness and dark urine.
