Pinyin
ǒu xuè
Simplified
呕血
Literal
嘔血 ǒu xuè — blood brought up, twice in this chapter's counterflow catalogue: in greater yang inversion after a stiff collapse, and again in yang brightness alongside panting, coughing, fright and nosebleed. The chapter offers no comment on either; the compound carries its own weight.
Shuowen
《說文解字》：嘔，吐也；血，祭所薦牲血也。「嘔」讀 ǒu、**本篇5見**；「血」讀 xuè、**本篇2見，本站通例讀 xuè，不作 xiě**；**本站 ch40「溺血」已立目，此則自上出者**。

In brief

Blood vomited up. It is one of the few signs this chapter repeats across two entries, and in both it stands next to blood lost elsewhere — nosebleed in one, nosebleed again in the other — so that the pair reads as bleeding rather than as two symptoms.

When greater yang governs the heaven, and cold is in excess and prevails, cold qi comes out of season and water is about to freeze. Blood changes within and breaks out as abscess and sore. The people sicken with reversal, pain of the heart and vomiting of blood, blood passed below, snivelling and nosebleed, much sorrow, and dizziness with falling; the moving fire blazes fiercely and a violent rain turns to hail. The chest and belly are full, the two hands hot, the elbows cramped, the armpit rushing at the heart, a palpitating unrest, and no peace in the chest, ribs and stomach duct; the face is red and the eyes yellow, they belch often, the throat is dry, and in grave cases the colour is soot-dark with thirst and a wish to drink. The illness is rooted in the heart; the shenmen pulse is extinguished — death, not to be treated. This is what is meant by knowing the viscus from where the qi moves.
