Syndrome of confliction of wind and fluid in lung refers to the syndrome due to invasion of pathogenic wind which prevents the lung from dispersing, descending and regulating water passage as well as causes extravasation of fluid and dampness in the skin. This syndrome pertains to yang edema, usually caused by exogenous pathogenic wind attacking the lung and failure of the lung to disperse, descend and regulate water passage which gives rise to stagnation of wind, retention of fluid, confliction between wind and fluid as well as extravasation of fluid in the skin.

Clinical manifestations:
Primary dropsy of the eyelids and face, eventual edema of the whole body with rapid development, thin and bright skin, scanty urine, accompanied by aversion to cold, fever, no sweating, whitish thin tongue fur, floating and tense pulse; or accompanied by swelling and pain of throat, reddish tongue as well as floating and fast pulse. These manifestations are usually seen in acute nephritis, pyelonephritis and acute onset of chronic nephritis, etc.

Analysis of symptoms:
Primary dropsy of eyelids and face, eventual edema of the whole body with rapid development as well as thin and bright skin are due to invasion of pathogenic wind into the lung which prevents the lung from dispersing, descending and regulating water passage as well as causes confliction between wind and fluid and extravasation of fluid; scanty urine is due to failure of the upper energizer to disperse and loss of qi transformation. If accompanied by aversion to cold, fever, no sweating, whitish thin fur as well as floating and tense pulse, it is the syndrome marked by confliction between wind and fluid with superficial cold; if accompanied by swelling and pain of throat, reddish tongue and floating and fast pulse, it is the syndrome marked by confliction between wind and fluid with superficial heat.

Key points for syndrome differentiation:
Sudden onset of edema of the eyelids and face first with quick involvement of the whole body, scanty urine, accompanied by aversion to cold and fever, etc.
