Professor Wang Wei believes that the function of the spleen is closely related to xerophthalmia. The spleen is the required foundation. The dysfunction of the spleen can lead to the dysfunction of many viscera, resulting in "yin deficiency", "yang deficiency" and "channel obstruction". The biochemical deficiency of body fluid or excessive consumption of body fluid can lead to xerophthalmia, which should be treated from the spleen. Young and middle-aged patients have sufficient healthy ,qi, and mostly yin deficiency and dampness-heat syndrome. The treatment should focus on nourishing yin and clearing heat of middle energizer, so Huangqin (,Radix Scutellariae,), Zhizi (,Fructus Gardeniae,), Shengdihuang (,Radix Rehmanniae,), Juhua (,Flos Chrysanthemi,), Bohe (,Herba Menthae,), Jinyinhua (,Flos Lonicerae Japonicae,), etc. to clear heat, Baidoukou (,Fructus Amomi Kravanh,), Cangzhu (,Rhizoma Atractylodis,), Fuling (,Poria,), etc. to invigorate spleen and drain dampness, Maidong (,Radix Ophiopogonis,), Yuzhu (,Rhizoma Polygonati Odorati,), Beishashen (,Radix Glehniae,), Nanshashen (,Radix Adenophorae,), etc.to nourish lung-stomach yin. Xerophthalmia is related to yin deficiency, dampness-heat,qi, stagnation and emotion, and so the treatment should also pay attention to emotional problems. Yin and yang interact with each other. If there is no yang, then yin will not be transformed. The spleen is in charge of ascending yang, if it fails, then the essence and ,qi, cannot ascend to nourish the head, face and five sense organs, and the body fluid cannot be transfused tomoisten the eyes. Therefore, the treatment should also considering ascending yang ,qi, and Shengma (,Rhizoma Cimicifugae,), Chaihu (,Radix Bupleuri,) are often added to regulate emotions and ascend yang ,qi,.
