Materia Medica Shu Gou Yuan

"Ben Cao Shu Gou Yuan" is a work that refines and sublimates Liu Ruojin's "Ben Cao Shu". Liu Ruojin's "Compendium of Materia Medica" is good at elucidating the philosophy of medicinal properties and integrating the theories of doctors from the Jin and Yuan Dynasties, but the content is vast. Yang Shitai was deeply aware of its value, so he "cut out the complexity and captured the key points" and systematically organized, deleted and refined it, so it was called "Gouyuan". He retained the profound pharmacological discussions and rich clinical insights in "Ben Cao Shu", making its purpose clearer and clearer, making it easier for doctors to master and apply it. This book is a representative work of Qing Dynasty Materia Medica that attached great importance to the combination of medicinal theory and clinical practice. It has important reference value for in-depth understanding of the mechanism of drug action.
