The T.C.M. Formula Study Guide is a quick-reference manual and in-depth study guide for the most important 130 classic herbal prescriptions used in Oriental medicine. It consists of three parts. In the first part, each formula is broken down by individual herb functions, allowing an in-depth analysis of the formula's interrelated functions. The accompanying syndrome differentiation charts and formula comparison charts help clarify treatment aims, as well as differences between similar formulas. Each chapter ends with a review and discussion of the major formulas in that section. The symptom differentiation charts allow easy clinical reference to assist with accurate formula selection. They are based on differentiation according to the zang fu and six-stage syndromes, which are broadly organized by exterior/interior and excess/deficiency types. The comprehensive exam allows the student to self-test their knowledge of the formulas themselves and their clinical applications through formula and case study questions.
