溲血

sōu xuè

Blood in the urine · sou xue

Also rendered: Blood in the urine (this site; literal from the two graphs, and it keeps 溲 as the act of passing water rather than importing a clinical label) · Bloody urine (the plain clinical phrase, which is what the site uses for 溺血 niào xuè and is therefore kept distinct from this entry)

Pinyin
sōu xuè
Simplified
溲血
Literal
溲 sōu — to pass water; 血 xuè — blood. Blood in the urine. The chapter names it once, in the rough branch of the lesser yin: 少陰有餘，病皮痺隱軫；不足，病肺痺；滑則病肺風疝，濇則病積溲血. The two things in that branch — 積, accumulation, and 溲血, blood in the water — are what a rough pulse means here, and the chapter gives them together and says nothing more. The site reads 溲 as sōu from chapter 37 onward, where it means urinating rather than the soaking and steeping the graph has elsewhere. The same thing written with another graph is already an entry of its own on this site — 溺血 niào xuè — and the two are kept apart, each as its own base text writes it.

In brief

Blood in the urine — 溲 sōu, to pass water; 血 xuè, blood — and this chapter names it once: 少陰有餘，病皮痺隱軫；不足，病肺痺；滑則病肺風疝，濇則病積溲血. It is the rough branch of the lesser yin, and it comes in the same breath as 積, accumulation — a rough pulse is short of blood, and what the chapter gives it is a gathering and a bleeding. The line can be read either way, as two things or as one thing and its discharge, and the base text writes them with no punctuation between them; both readings are kept here. The site reads 溲 as sōu, to urinate, as it has from chapter 37 onward. The same condition written with another graph — 溺血 niào xuè — is already an entry on this site; the two are not merged, because each is what its own base text writes.
