Selected Records of Li Fazhi's Formula-Pattern Differentiation

Li Fazhi's Selected Case Records of Formula-Pattern Differentiation is a highly valuable clinical monograph on the practice of classical formulas. Its core academic value lies in the close integration of the pattern-differentiation system of the Treatise on Cold Damage with extensive clinical experience. This book is not a simple compilation of formulas; rather, through the systematic organization of Professor Li Fazhi's decades of clinical case records, it profoundly elucidates the essence of "formula-pattern correspondence." The cases are detailed, and the pattern-differentiation process is clearly structured. In particular, in the dialectical thinking of "grasping the main pattern," it demonstrates the author's deep grounding in the Treatise on Cold Damage and keen clinical insight. For learners of classical formulas, the book's greatest inspiration lies in its departure from the mechanical thinking of "fitting formulas to diseases," guiding readers back to Zhang Zhongjing's dynamic spirit of pattern differentiation: "Observe the pulse and signs, know what contravention has occurred, and treat according to the pattern." The differentiation of similar formula-patterns, the consideration of changes in drug dosage, and the layer-by-layer analysis of complex pathomechanisms all reflect Professor Li Fazhi's distinctive academic views and pragmatic clinical style. Reading this book, one can not only learn specific applications of formula-patterns but also deeply comprehend the soul of pattern differentiation and treatment in Chinese medicine. It is an advanced reader that can effectively enhance clinical thinking ability.
