论述说：《内经》提到，胆将热邪转移至脑部，就会引发鼻渊。所谓鼻渊，是指浑浊的鼻涕不断流出。脑是髓海，藏于至阴之位，所以具有“藏而不泻”的特性。如今胆经的邪热上入于脑，导致阴气不固，原本应闭藏的脏腑反而发生了泄漏，因此脑中的津液下渗进入鼻腔，其症状表现为浊涕不止，就像水源有源头一样源源不断。如果治疗不及时，病情传变，可能会发展为鼻衄（鼻出血）或目瞑（昏厥、眼睛闭合）。

It is stated in the discussion: The *Neijing* (Inner Canon) mentions that when Gallbladder Heat transfers to the Brain, it results in Bi Yuan (Nasal Sinusitis with purulent discharge). Bi Yuan refers to the continuous flow of turbid nasal mucus. The Brain is the Sea of Marrow, residing in the Supreme Yin, and thus possesses the characteristic of "storing without draining." Now, when pathogenic heat from the Gallbladder moves upward into the Brain, the Yin Qi becomes insecure, causing what should be stored to leak out. Consequently, brain fluids seep downward into the nose, manifesting as continuous turbid nasal discharge, much like a spring with an inexhaustible source. If treatment is delayed, the condition may transmit and develop into Bi Xue (Epistaxis/Nosebleed) or Ming Mu (Syncope/Closed eyes).
