Traditional Chinese Medicine

On a small set of very old texts that our articles keep returning to. The Huangdi Neijing, in its two halves the Su Wen and the Ling Shu, supplies the physiology: qi that rises at dawn and empties at dusk, the protective yang identified with sunlight itself, the explanation of why older people sleep badly. The Shang Han Lun and the Jin Gui Yao Lue supply the formulas. The Bencao Gangmu of 1596 supplies the materia medica, indexed by disease, which is what lets us check whether a herb was ever aimed at a given condition. Two more appear regularly: the Nan Jing and the seventh-century Beiji Qianjin Yaofang.

Our own tally is the most useful thing we can offer. Of thirty-five Chinese-medicine claims we checked, three were confirmed by research, seventeen had partial support, two were refuted, and thirteen had never been tested. Two of those numbers deserve emphasis together: refutation is rare, at two out of thirty-five, but so is confirmation, at three — and more than a third of the claims sit in the untested column. The sample follows our topics rather than the tradition's own priorities, so it measures what we asked, not what Chinese medicine is.

In the founding text, the answer is not a medicine. The Su Wen identifies the body's protective yang with sunlight and has it track the sun across the day, then gives seasonal instructions instead of a remedy: wait for daylight before rising in winter, do not shun the sun in summer. Every boundary it uses to divide the day is a light event rather than a clock time. Later Chinese pharmacy did develop sleep formulas, and the classics elsewhere explain sleeplessness through the distribution of qi — but where a modern reader expects a herb, the founding text offers an exposure schedule.
