1 External syndrome
External syndrome refers to the symptoms appearing at the primary stage of exogenous diseases caused by invasion of six pathogenic factors into the body through skin, mouth and nose, marked by sudden onset, short duration and shallow location.
Clinical manifestations: The clinical manifestations are fever, aversion to cold (or aversion to wind), thin and white fur and floating pulse, accompanied by stuffy and running nose, sore-throat and cough.
Analysis of the symptoms. Attack of pathogenic factors against the superficies and confliction between healthy qi and pathogenic factors lead to fever and aversion to wind and cold; stagnation of pathogenic factors in meridians prevents meridian qi from free flowing and results in pain; the lung governs skin and hair, the nose opens into the lung and the throat is the door of the lung, so attack of pathogenic factors against the surface of the body leads to dysfunction of the lung and causes stuffy and running nose, sore-throat and cough; the pathogenic factors retain in the superficies and have not damaged the interior, so the tongue fur is still thin and white without change;floating pulse is the sign of external confliction between
the healthy qi and pathogenic factors.
