Inner Vision Viscera Chart 黄庭内景五脏六腑补泻图

Originally attributed to "Hu Yin, the Jiansuzi of Taibai Mountain".

Completed in the late Tang Dynasty, it was recorded as "Hu Yin’s Huangting Neijing Tu, one volume" in New Book of Tang·Bibliography of Arts and Literature—this is exactly the book in question.

The version in The Daozang is included in the Spiritual Chart Category of the The Dongxuan Section, and there is another version collected in Xiuzhen Shishu (Ten Books of Cultivating Truth). At the beginning of the book is Hu Yin’s preface written in the second year of the Dazhong reign period of Emperor Xuanzong of Tang (848), stating that the author, who lived a quiet and indifferent life, was fond of reading the Huangting Jing. Finding that the texts and theories of the old charts were profound and abstruse, she compiled her own insights, based on various scriptures, and created new illustrations.

From this, it can be seen that this book was actually adapted by Hu Yin from the old version Huangting Wuzang Liufu Tu (Illustrated Charts of the Five Zang-Organs and Six Fu-Organs of the Yellow Court). Integrating Taoist health-preserving practices of daoyin (guiding qi) and circulating Qi with medical theories of zang-fu organs and blood vessels, the book is divided into six sections corresponding to the lung, heart, liver, spleen, kidney, and gallbladder, elaborating on the principles and methods of health preservation in detail. Each section starts with an illustration, explaining the physiology and pathology of the five zang-organs and six fu-organs, followed by enumerations of health cultivation methods, disease diagnosis methods, simplified prescriptions for treatment, qi-circulating methods, dietary taboos, and daoyin methods. The entire text is concise and the discussions are practical, making it a comprehensive work related to physiology, hygiene, medicine, and cultivation, which also reflects the integration characteristics of Taoism and traditional Chinese medicine in the late Tang Dynasty.
