Hyperhidrosis is a common clinical disease. Professor ZHANG Huailiang is the fifth batch of instructor of the State Administration of China to inherit and pass on the experiences of veteran Chinese medicine experts. He is good at treating miscellaneous diseases by using classical prescriptions. Professor ZHANG believes that the clinical syndrome differentiation of hyperhidrosis can be divided into deficiency and excess. Deficiency syndrome includes Yin deficiency, Qi deficiency, Yang deficiency, deficiency of Yin and Yang, as well as imbalance of Ying and Wei. In terms of excess syndrome, it can be classified into phlegm, dampness-heat and blood stasis. Based on clinical cases, this paper introduced eight treating methods for hyperhidrosis and elaborated the thinking of syndrome differentiation and treatment of hyperhidrosis. Five methods for deficiency syndrome include nourishing Yin and clearing heat, nourishing Spleen and replenishing Wei, reinforcing Yang and strengthening superficial resistance of the body, nourishing Yin and replenishing Yang, harmonizing Ying and Wei. Three methods for excess syndrome include clearing heat and expelling phlegm, clearing dampness and heat, activating blood circulation and removing blood stasis. Professor ZHANG Huailiang has unique thinking and rich experience in the treatment of hyperhidrosis, which has important guiding significance and is worth emulating.
