The cause of this disease is either exogenous or endogenous. Exogenous cause refers to attack by wind, cold, heat and dryness that lead to non-conveyance of pulmonary qi, failure of body fluids to distribute and obstruction of the trachea by sputum. Endogenous cause refers to dysfunction of the lung, spleen and kidney. Lung asthenia results in failure of pulmonary qi to convey and descend; dysfunction of the spleen leads to accumulation of dampness into phlegm which attacks the lung; kidney asthenia brings about dysfunction of qi and upward adverse flow of qi; or invasion of liver fire into the lung leads to consumption of body fluid by lung heat.
