This paper introduced YU Jingmao′s experience in treating refractory asthma in children. It is believed that wind

cold and dampness are the most common causes of the disease

and phlegm and heat are the main pathogenesis

which are combined with blood stasis and toxicity. It is emphasized that the treatment should be related with five zang-organs

and that the lung should not be treated alone

instead of treating from the liver

the spleen and stomach

the kidney

and the heart. At the same time

the application of insect drugs to expel wind

dredge collaterals and relieve asthm should be focused. We should combine multiple methods to one formula for both clearing and tonifying

treating the manifestations and root causes

so as to achieve the goal of clinical control.
