Taking a comprehensive view of the medical syllabus, there are no external principles, methods, or prescriptions. These four words are the essence of medicine and also the guide for doctors. Reason is the philosophy of medicine, which is the understanding and understanding of the human body, as well as the diagnosis and judgment of diseases. Law is the methodology of medicine, which refers to how to effectively treat and prevent diseases. Fang is a medical prescription that is a treatment plan formulated based on the condition and type of disease. Medicine is a medical treatment method that treats and recovers patients.

综观医学大纲，不外理法方药四字。这四个字，是医学的精髓，也是医者的指南。理，是医学的哲学，是对人体的认识和理解，是对疾病的诊断和判断。法，是医学的方法论，是指如何针对疾病进行有效的治疗和预防。方，是医学的处方，是根据病情和病种制定的治疗方案。药，是医学的治疗手段，是对病人的治疗和康复。

理法方药四字，不仅涵盖了医学的各个方面，也体现了医学的精神和理念。理是基础，法是手段，方是核心，药是实施。只有理清了疾病的本质，才能制定出有效的治疗方案；只有掌握了正确的方法，才能更好地进行治疗；只有选对了合适的处方，才能更好地为病人服务；只有选对了合适的药物，才能更好地为病人带来康复。
