Herbal Formulas is the forth volume in the "Practical Traditional Chinese Medicine and Pharmacology" series. 138 of the most effective and commonly used formulas in Chinese medicine are introduced in this book. Unlike most books of this kind, Herbal Formulas does not merely list each formula's functions, indications, applications and composition, but also provides charts and detailed analyses of the causes and physical manifestations of the symptoms each formula is effective for and the curative contribution of each individual herb.

Formula modifications are included to account for symptom variation. The formulas in this book do not appear therefore as incomprehensible combinations of individual herbs but rather as models of integration between basic TCM theories and knowledge of medicinal herbs. In illustrating the internal working relationship of the herbs in each formula, this book enables the TCM clinician or practitioner to learn how to make prescriptions on their own.
