方晓苓——谈生石膏之清透凉降之性

Fang Xiaoling——talking about the Qingtou Liangjiang of raw gypsum

生石膏性寒,则具清热之功;其味辛,主散,则具透邪外达之功;其入肺胃经,主治中上二焦热证,而不侵及下焦。石膏虽味辛,具有透散之性,但它与其他普通的寒凉药同样具有质重沉降之性,石膏沉降之性能折上逆之气使之下行,从而起到凉降的作用。生石膏的清透及凉降之性在临床应用中往往是同时发挥,二者不可分割,也正因如此,生石膏在热病中的使用非常广泛,深受医家推崇。

Gypsum with Han(寒),has the function of Qingre(清热);its has the function of Touxie Waida(透邪外达).It enters the Feiwei(肺胃)meridians,and treats the middle and upper Erjiao(二焦)heat syndrome without invading the Xiajiao(下焦).Although gypsum is pungent and has a penetrating property,it has the same quality as other common cold medicines.The gypsum settling performance is reversed to make it go down,thus playing a cooling role.The clearness and coolness of gypsum are often exerted simultaneously in clinical applications,and the two are inseparable.Because of this,gypsum is widely used in fever and is highly praised by doctors.
