Each entry gives the term in traditional and simplified form, its pinyin, the senses it carries in the classical corpus, the passages where it does real work, and how published translations have rendered it.
tiān nián
The span allotted at birth: a hundred, in this chapter. It functions as a measure rather than a promise — the chapter's question is why people fall short of it, and the answer it gives is conduct.
fāng cǎo
The fragrant, warming herbs. Chapter 40 forbids them in heat-within and wasting-within: their qi is swift and hard, and in a body already hot they drive the patient to madness.
kuí duó
One of the two arts the chapter sets side by side, and the one that answers the ordinary clinical question: how deep does this go? Qibo's definition is a single clause — 揆度者，度病之淺深也. The chapter then does something more interesting with it: it refuses to let the two arts stay separate, and says that colour, pulse, assessment and the anomalous are all one dao. 揆度 is the measuring half of that pair; 奇恒 is the half that names what cannot be measured by the rule.
qí héng
The other of the chapter's two arts, and the harder one: the anomalous is what the rule does not cover. Qibo defines it in three words — 奇𢘆者，言奇病也, it speaks of strange illness — and the chapter spends the rest of its length showing what that means in practice: colour on the wrong side, doubled yang, a pulse with no stomach qi in it, a disease travelling into the organ that conquers it. The same word gives 奇𢘆之府 in chapter 11, the palaces that hold rather than transmit — there too it marks what breaks the rule.
