Etiology — the 1 books the tradition kept on this shelf
A court-commissioned catalogue of causes — the earliest attempt to write down, for each symptom, what disorder could be behind it, without prescribing. As a diagnostic checklist it is closer to a modern symptom index than to a formulary.
Every entry below is taken from the same catalogue the product is built on: the title, the hand behind it, when it sits in time, what the book works on, and what it changed. Sentences in bold are the ones we can point an outside source at; the rest is our summary of the book, not a claim from it.
Treatise on the Origins and Symptoms of Diseases (诸病源候论)
隋·巢元方 · Sui (610) · Zhu Bing Yuan Hou Lun
Works on: Where diseases come from and what they look like. The running heads of our edition go from scroll one to scroll fifty under class labels that carry their own census — wind disorders, upper part, twenty-nine essays; sores, sixty-five essays — and within them each entry is numbered: the first, wind-stroke; the seventh, wind cramp. An entry explains the cause, then lists how the complaint shows on the body and which turnings mark it beyond treating, and some close with two optional sections labelled ways of nourishing life and ways of guiding the breath.
What it changed: Its smallest unit is the "sign": each states the cause first — wind, cold, damp, wasting, diet, dwelling — then the outward shape, the turning, and whether it can be treated, splitting reasoning from recognition. The preface explains the commission: earlier books were incomplete and crude practitioners guessed, so the court ordered this one cut into blocks and spread across the empire. It is the first Chinese text to systematise causes and their signatures; Korean and Japanese physicians quarried it for centuries.
Where this leaves our product
Qicura reads a described symptom against this kind of material and returns a pattern in plain language with the sources named. It does not dispense: no herb quantities, no formula composition, no preparation instructions, and no needling technique - those are deliberate limits enforced on the server, not wording we soften for a page.
Educational, self-care content - not a medical diagnosis. For personal advice, consult a qualified practitioner.
