Notes:
Extraordinary Vessel attributions come from Li Shi-Zhen's (1577-8) Exposition on the Eight Extraordinary Vessels (Qi Jing Ba Mai Kao), trans. Chace & Shima (2009). It should be followed by Xiao Jian Zhong Tang. Shen Jin-Ao also considered it for Yin Qiao Mai pathologies but the indications do not seem to fit any Yin Qiao symptoms given in the classics.

---------------------------------------

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).
