Professor Feng Xian-zhang believes that the early onset of chronic urticaria is mainly marked by excess syndrome, and the main causes are wind, cold, heat, phlegm, dampness and blood stasis.In the later stage, deficiency syndrome is the main syndrome, which needs to strengthen healthy qi and dispel pathogens.If wind pathogen is mixed with cold pathogen or heat pathogen, it will become wind-cold syndrome or wind-heat syndrome.Dampness pathogen is a kind of disease, which is easy to combine with heat pathogen to accumulate dampness and heat.If the disease lasts for a long time, the spleen and stomach will be damaged, the spleen deficiency and dampness retention will appear, the dampness and heat will be endogenous, burning the body fluid and causing phlegm.Based on this, Professor Feng has established the treatment methods of"ventilating the lung, dispersing cold, eliminating wind and relieving itching", "clearing heat and expelling pathogens through the exterior, dispersing wind and relieving itching", "pacifying the liver to extinguish wind, soothing the liver and relieving depression".At the same time, Professor Feng stresses that when giving prescriptions, it is necessary to treat according to individual, time, and place.According to the characteristics of the disease, "dispelling wind and relieving itching" is advocated throughout the whole course.In addition to treatment, patients also need to pay attention to the regularity of life and rest, light diet, adjust sleep and regulate mood, so as to promote the recovery of the disease.
