Notes:
Zhang Zhong-Jing states that this formula treats the accumulation of water in the Middle Jiao to prevent it entering the intestines and becoming diarrhoea, and that the sensations of cold in the limbs should be treated afterwards.

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).
