To summarize Professor ZHANG Zhiyuan's experience in treating leukorrheal diseases based on syndrome differentiation. It is believed that the main pathogenesis of leukorrheal diseases includes mainly depression， dampness and deficiency. Leukorrheal diseases can be classified into four syndrome types： syndrome of stagnation of liver

qi

and spleen deficiency， syndrome of internal retention of damp-heat， syndrome of cold-dampness invading downward， and syndrome of kidney

yang

deficiency. The treatment approach focuses on restoring the ascending and descending opening and closing of

qi

， regulating the liver and spleen to promote

yang qi

respectively. The four types of syndromes correspond to the application of four different herbal formulas： By using the combination of

Danggui Shaoyao

Powder

（当归芍药散） from the

Synopsis of Golden Chamber

（《金匮要略》） with wind-dispelling herbs， adjustments are made to harmonize the liver and spleen； By applying modifications to the

Baxian Drink

（八仙饮） from the

Obstetrics Enlightenment

（《产科发蒙》） to clear heat and promote diuresis； A self-designed

Shiwei Wendai Decoction

（十味温带汤） is adjusted to warm the

yang

and dispel cold； The

Baji Tusi Decoction

（巴戟菟丝汤） from the

New Compilation of Effective Recipes

（《验方新编》） is adjusted to tonify and warm the kidney
