Pinyin
bāo mài
Simplified
胞脉
Literal
胞 bāo, the womb, the enclosing organ; 脉 mài, vessel. The vessel that belongs to the heart and nets into the womb, and whose closing is given as the reason the menses stop. Two lines of the chapter carry the whole of gynaecological physiology in this text: the womb vessel belongs to the heart and connects into the womb, and when qi presses upward on the lung the heart qi cannot pass downward — so the menses do not come.

In brief

The vessel that belongs to the heart and nets into the womb. Its closing is the chapter’s explanation for absent menses in wind water: the qi presses upward on the lung, the heart qi cannot pass down, and so the menses do not come. The chapter’s point is that the womb is not itself diseased — the passage of qi to it has been cut off from above.

Every rendering below is a decision about which reader is being addressed. There is no neutral option.

Wiseman & Fengwomb vesselThey render 胞 as womb, which is what the chapter means by it in this context.
Unschuldvessel of the wombUnschuld spells out the relationship, which suits a passage that is defining the vessel's course.
This sitevessel of the wombWe keep 胞 as womb and 脉 as vessel. This is the one place in the chapter where an anatomical claim is made outright, and it should be translated as a claim rather than softened.
