The source of Poria is the dried fungus of Poria, family Polyporaceae, which is sweet, light and flat in nature, with the effects of diuresis, dampness, spleen and heart, and can be used in the treatment of edema and urinary deficiency, phlegm and vertigo palpitation, deficiency of the spleen with little food, loose stools and diarrhea, as well as disturbed mind and spirit and palpitation and insomnia, and so on.
