Further Discussion on Dongyuan's"Yin Fire"Theory Based on Pi Wei Lun
Based on the book of Pi Wei Lun,this paper mainly discusses the meaning,etiology,pathogenesis and treatment of Li Dongyuan's Yin fire.Li Dongyuan believes that Yin fire is a pathological condition in internal injuries,which is composed of"deficiency"and"heat"."Yin"means interior."Deficiency"means Qi deficiency,which mainly refers to Qi deficiency of spleen and stomach.The weak Qi can't move upward or outward and trapped in the Yin,which is the reason for the"heat".Yin and blood are agitated by the heat.The heat is carried throughout the body with the flow of blood.Tonifying spleen and stomach and raising Yang Qi are the fundamental and main methods for the treatment of Yin fire.And clearing heat is a palliative method for Yin fire.
