Location. In the mouth, on the floor of the mouth, on the sublingual vein to the right of the frenulum of the tongue; the point is taken with the mouth open and the tip of the tongue raised to the palate.
The name mirrors the preceding one: yu is jade and ye is fluid, so Jinjin and Yuye, gold fluid and jade fluid, are named together for the saliva that collects under the tongue. This entry follows the common textbook assignment, with Yuye on the right of the frenulum and Jinjin on the left. It is a point outside the fourteen channels. The two are recorded as a pair and are almost always described in the same breath, which is worth saying plainly because a reader will not find separate classical discussions of each: what is written about one is written about both. Classical sources record pricking the vein to release a drop of blood, and later literature discusses the pair in the context of the tongue, of speech and of the mouth. The classical record is thin, the reported effects are not established by modern research, and this entry makes no claim of benefit.
定位。在口腔内，舌下系带右侧的舌下静脉上；张口、舌尖上卷抵上腭取之。
穴名与前穴相对：「玉」为玉，「液」为津液。金津、玉液两名并取舌下汇聚之唾液，成对而立。本条从通行教材之说，玉液在右、金津在左。为十四经之外的奇穴。两穴成对，文献几乎总是相提并论——这一点值得明说：读者不会在古典文献中找到分别讨论两穴的独立篇章，凡言其一者即兼言其二。古典记述有以针点刺该静脉出血少许者；后世文献多于舌、言语与口舌的语境下讨论本对穴。本穴古典记载较简，所述作用未经现代研究证实，本条不作疗效陈述。
