Pneumoconiosis is a systemic occupational disease caused by large amount of inhaled silicon dioxide

coal dust and other dust in lungs

which leading to diffuse silicotic nodule and fibrosis. Prof. WANG Shuchen thinks that

this disease is due to the coagulated dust hurting the lungs

gradually to form blood stasis blocking the collaterals in lungs and hurting healthy atmosphere. The excessive pathogen leads to the disease

and the excessive pathogen leads to the deficiency

forming the filled pathogen

weakened body resistance

simultaneous insufficiency and excessive. It makes the pneumoconiosis to be lingering

repeated and unhealed. WANG Shuchen thinks the blood circulation should be promoted to remove blood stasis throughout the entire clinical treatment

and dredging collaterals should be combined to release pain and tonifying kidney Qi.
