It points out that the core pathogenesis of the disease is the invasion of wind-cold-damp pathogens into the exterior region, leading to stagnation of defensive Yang and obstruction of orifices and collaterals. Through three typical clinical cases (involving symptoms such as nasal itching, nasopharyngeal tube obstruction, nasal congestion with headache), modified ephedra-based formulas such as Mahuang Decoction, Maxing Shigan Decoction, and Xiaoqinglong Decoction are used, combined with drugs for inducing resuscitation, resolving dampness, and promoting blood circulation, to expel pathogens through diaphoresis. Clinical observations show that expelling pathogens with the “diaphoresis method” can effectively relieve symptoms with significant curative effect. This study provides new ideas and methods for expanding the application of the “diaphoresis method” in the treatment of sinusitis.
