Notes:

There is no information from Chinese sources but accounts on its use as an emetic and its ability to treat smoking addiction has made me draw the judgement that its use would be to expel malevolent forces that compel us act in ways to shorten our lifespan such as Gui / Ghosts, Sanshi / Three Corpse Posession and Po / the Corporeal Soul. These are often classed as Phlegm misting the Heart in TCM.
