Abstract: The study summarizes the experience of Dong Qimei, the instructor of the inheritance of academic experience of famous traditional Chinese medicine experts, in using Yueju Pill to treat palpitations, thoracic obstruction, and hypertension from "constraint syndrome" based on the same treatment for different diseases in heart system. Dong Qimei believes that the pathogenesis of heart diseases "begins with qi constraint, develops in phlegm-stasis, and changes to liver wind and liver fire", and also pays attention to the role of damp-turbidity in heart diseases. Thus, she proposes "treating heart diseases according to qi-constraint and damp-stagnation by narrowing down the range of heart diseases from the meaning of the formula of Yueju Pill". In addition, she considers that the key to treating heart diseases with Yueju Pill in clinical practice is to focus on qi-constraint in other complicated pathogenesis caused by constraint syndromes, to identify the differences in symptoms of palpitation, irritation, stuffiness, pain and dizziness, and to differentiate clinical signs based on the greasy tongue coating with deep pulse. She also introduced the clinical experience of applying Yueju Pill through typical cases to expand the clinical application of that classic formula.
