Location. In the mouth, on the floor of the mouth, on the sublingual vein to the left 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 pairs jin, gold, with jin, fluid: a precious fluid, that is, the saliva that collects under the tongue. Together with Yuye (EX-HN13) on the other side of the frenulum it forms a pair, and the two are always recorded together. This entry follows the common textbook assignment, with Jinjin on the left and Yuye on the right. It is a point outside the fourteen channels, and it is one of very few points whose recorded site is a vein rather than a hollow or a bone. 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，舌下系带左侧的舌下静脉上；张口、舌尖上卷抵上腭取之。
穴名以「金」配「津」，谓贵重之津液，即舌下汇聚之唾液。与对侧的玉液（EX-HN13）成对，分居舌系带两侧，文献恒并记之。本条从通行教材之说，金津在左、玉液在右。为十四经之外的奇穴；多数穴以凹陷或骨性标志定位，本穴是极少数以静脉为定位标志者。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。
