RESUMEN
The classic acupuncture theory is an important component of the basic theory of TCM. Due to clinical disciplinary division and other factors, the relationship of acupuncture theory with each division of "Chinese herbal formula and pulse" has been gradually alienated. In this paper, by taking the progress of syndrome/pattern differentiation and treatment of 3 medical cases as the examples, the feasibility of clinical application of classical formulas guided by the classic acupuncture theory and clinical effect are explained. It shows that the accuracy of syndrome/pattern differentiation and the therapeutic effect can be obviously improved if the classic acupuncture theory is correctly applied to the syndrome/pattern differentiation and treatment with classical Chinese herbal formulas. It also proves the inner communication and high complementarity in terms of the theory between acupuncture and classical Chinese herbal formula. It is anticipated to provide the references for the theoretic integration among academic disciplines and for the mutual reference as well as for the application of the characteristic theories among specialties.
