Diagnosis of CFS was determined by conventional medicine criteria(CDC criteria for CFS), physical examination, and routine laboratory tests. TCM diagnosis of CFS relied on Four Examination Methods and Eight Principal Patterns. They were diagnosed as Ganyu Qizhi (liver and qi stagnation) and Pixu Qiruo (spleen and qi deficiency). The treatment method is to disperse the liver and facilitate qi, rehabilitate the spleen and strengthen qi (Shugan Liqi, Jianpi Yiqi). The result of the treatment indicated that the total effective rate was 100% in terms of fatigue, difficulty concentrating, headache, sore throat, muscle pain, joint aches, feverishness, rapid pulse, insomnia, depression, irregular menses, abdominal cramps, and night sweats. The percentages of specific symptoms of CFS in the patients were comparable to the conventional medical record (Table 1).展开更多
