Apart from "different syndrome complexes in the same disease" and "the same syndrome complex in different diseases", another relationship between disease and syndrome complex is "analogous syndrome complex in the same disease" which means that the patients who suffer from the same disease manifest the common basic syndrome complex in spite of slight differences in their accompanying symptoms. So we can use a basic Chinese herb formula to treat these patients through slightly modifying the prescription for the sake of their accompanying symptoms when giving the medicine to each patient. The principle of "analogous syndrome complex in the same disease" emphasizes the homogenicity of disease and syndrome complex, further integrating "treatment based on the disease-diagnosis" and "treatment based on the syndrome complex-differentiation". It is important to study the principles of "analogous syndrome complex in the same disease and treating the same disease with analogous methods". This will be beneficial to both interpretation of the connotation of syndrome complex with modern science and technique, and development of the advantages of syndrome differentiation treatment and individualized treatment in traditional Chinese medicine. The clinicians should fully understand the theory of "formula corresponding to the syndrome complex" and treat the patients based on syndrome differentiation.
