The Classics 经典
“Three books built this medicine — a dialogue, a fever manual, and an encyclopedia. Everything in my nine halls is a footnote to one of them, including me.”
— Lao Xinglin
Huangdi Neijing (黄帝内经) — the foundation
The Yellow Emperor's Inner Classic, compiled roughly two thousand years ago as a dialogue between a legendary emperor and his physician: not a recipe book but the medicine's constitution, laying down qi, yin-yang, the five phases, the channels, and the ideal that superior medicine treats before illness arrives[1]. Every concept page in this grove is, knowingly, commentary on it.
Shang Han Lun (伤寒论) — the method
Zhang Zhongjing's third-century Treatise on Cold Damage: the book that turned theory into prescriptions. Written after epidemics devastated his clan, it tracks how febrile disease moves through stages and answers each with an exact formula — many still in daily use, Gui Zhi Tang's family among them[1]. It is the ancestor of every "pattern → formula" page in the Formula Book, and physicians in East Asia still memorize its lines.
Ben Cao Gang Mu (本草纲目) — the encyclopedia
Li Shizhen's 1596 Compendium of Materia Medica: nearly 1,900 substances, a life's work of collection and — notably — correction, with Li testing claims and flagging errors of earlier herbals[1]. It is the Herb Cabinet's great-ancestor, and its skeptical streak is the one this site tries hardest to inherit.
How to read them today
As the tradition's source code, not as settled science: brilliant systematic observation, pre-modern theory, and the raw material that modern trials now sift — the sifting being exactly what our evidence shelf is for[2]. When a formula page says "from the Shang Han Lun, c. 200," you now know the weight that citation carries: eighteen centuries of continuous use, which is remarkable, and is not the same thing as proof — a distinction this library exists to keep sharp.
