Abstract: Zhang Jianzhai's therapeutic methods for damp-warm pathogen disease were summarized according to his existing medical records， and eight therapeutic methods were obtained including dispelling wind， removing dampness and harmonizing collaterals， clearing heat and removing dampness， diffusing qi and removing dampness with aromatic herbs， regulating qi activities， dispersing evils by purgation， regulating middle energizer and strengthening the transportation of spleen， relieving dryness， venting and discharging， and nourishing yin and harmonizing the center. Zhang divided damp-warm pathogen disease into three phases， the disease location of the first phase is wèi qì， and that of the second and third phases are qi and ying. Among the eight therapeutic methods， dispelling wind， removing dampness and harmonizing collaterals are wildly used in the first phase， clearing heat and removing dampness， relieving dryness， venting and discharging are wildly used in the second and third phases. Relieving dryness， venting and discharging also can prevent transmission and change of the disease. Diffusing qi and removing dampness with aromatic herbs are used when heat is removed and dampness is retained， which is used for regulating qi activities and dispersing evils by purgation. Regulating middle energizer and strengthening the transportation of spleen are running through the treatment of damp-warm pathogen disease. Nourishing yin and harmonizing the center are used for recuperation after three phases.
