Ingredients

Zhi Gan Cao 6g
Zhi Fu Zi 12-15g (2 pcs)
Bai Zhu 6g
Gui Zhi 12g

Subsitutions:
In the UK Fu Zi must be substituted. Rou Gui and Xian Mao are the standard choice for joint pain. Since Gui Zhi is already in the formula then another Yang tonic that expels Wind-Damp-Cold from the channels like Yin Yang Huo might be more suitable.


Preparation: Decoction. The source text advises taking in 3 doses over the course of 1 day.A slight mild sweat should occur after taking showing the condition is being resolved.


Actions: Expels Wind-Damp-Cold and warms the Channels, supports the Yang



Notes:
One liang is taken as 3g in modern sources but in Eastern Han times it was equivalent to 13.875g. This means that the dosages in classical formulae could have been more than 4x what is given today making them far higher than recommended safe dosages today but prompts consideration of what an effective dose may be (He, 2013).
