Exogenous pathogenic factors

Exogenous pathogenic factors should always be eliminated from the body. Once that has been accomplished, focus on restoring the healthy balance of the body. 

This chapter introduces the principles, methods and strategies for the composition of formulas that stimulate the Qi in the superficial region, expel the exogenous pathogenic factors, and treat the exterior syndrome and other disorders that appear in this pathological process. 

When the pathogenic factors have remained in the body for a long period of time, deficiency of the Kidney, Liver, Qi and blood may coexist with the exogenous pathogenic factors. 

Treatment principle Expel exogenous pathogenic factors, promote Qi and blood circulation, tonify the Kidney and Liver, and tonify Qi and blood... 

Deficiency of Kidney, Liver, Qi and blood coexist with the exogenous pathogenic factors... 

External dryness is one of the six exogenous pathogenic factors it appears in the autumn and directly injures the Lung. In the early autumn, dryness is often combined with heat and it consumes the body fluid and Yin of the Lung - this syndrome is referred to as warm-dryness. In the late autumn, dryness is mainly combined with cold and causes obstruction of spreading of the body fluid of the Lung - this syndrome is referred to as cold-dryness. 

Since an exogenous pathogenic factor should be eliminated, a small amount of Bo He is used for this purpose. 

This combination is used to open the Qi obstruction that is caused by conflict between cold and warm, and excess of exogenous pathogenic factor and the weakened body resistance in the Middle-Jiao.
