鼻渊，又名脑渊。因为鼻子的孔窍，向上连通到脑户（头部后方的穴位/区域）。脑是髓汇聚的地方，就像天上的星宿海一样，奔流到底部。骨骼中的髓，发源于此。所以如果髓减少，就会出现骨头空虚、头颈低垂、眼睛深陷的症状，这是精神即将被剥夺的征兆。李濒湖说：鼻气与天相通。天，指的是头，也指肺。肺开窍于鼻，而阳明胃经的脉络，环绕鼻子向上行走。脑是元神居住的府邸，而鼻是命门（此处指代生命关键窍穴）的孔窍。如果人中气不足，清阳之气不能上升，就会导致头部低垂，九窍不通利。然而肺主皮毛，形体受寒或饮食生冷就会损伤肺脏。治疗的人只看到表面的症状，不探究根本原因，往往喜欢使用发散解表的方法。发散过度，起初流清鼻涕，随后变成单侧流涕，逐渐变得腥臭秽浊，黄色和赤色混杂，这都是因为脑户的渗漏开启，日积月累，导致身体极度消瘦虚弱。如果不是用参、芪来补益阳气，麦冬、五味子来收敛阴液，佐以辛夷透达鼻窍，脑户怎么能稳固呢？如果是虚寒证，少量加入细辛；如果有内热，用山栀来监制。又必须用六味丸加上鹿茸、枸杞等药物，在下焦填补肾阴，那么精气充足，髓自然充盈，哪里还会有像漏卮（有漏洞的酒器）一样的流失呢？

Bi Yuan (Nasal Sinusitis), also known as Nao Yuan (Brain Sinusitis). This is because the orifice of the nose connects upward to the Naohu (an acupoint/area at the back of the head). The brain is the sea of Marrow, similar to the Starry Sea in the heavens, flowing down to the bottom. The marrow within the bones originates from here. Therefore, if the Marrow decreases, symptoms such as empty bones, drooping head and neck, and sunken eyes appear, indicating that the Spirit is about to be depleted. Li Binhu stated: Nasal Qi communicates with Heaven. "Heaven" refers to the Head and also the Lung. The Lung opens into the Nose, while the meridians of the Yangming Stomach circle the nose and ascend. The Brain is the mansion where the Primordial Spirit resides, and the Nose is the orifice of the Mingmen (Gate of Life, here referring to a critical life orifice). If the Middle Qi of the person is insufficient and the Clear Yang fails to ascend, it leads to a drooping head and dysfunction of the Nine Orifices. However, the Lung governs the skin and hair; physical cold exposure or drinking cold beverages damages the Lung. Practitioners often only see the superficial symptoms without seeking the root cause, frequently preferring dispersing and resolving methods. Excessive dispersion causes clear nasal discharge initially, which later becomes unilateral rhinorrhea, gradually becoming fetid and turbid, mixed with yellow and reddish colors. All this is due to the leakage opening at the Naohu, accumulating day by day until the body becomes emaciated and weak. Unless Ginseng and Astragalus are used to tonify Yang, Ophiopogon and Schisandra are used to astringe Yin, and Xinyi (Magnolia Flower) is added to penetrate the orifices, how can the Naohu be secured? In cases of deficiency-cold, a small amount of Asarum is added; in cases of internal heat, Gardenia is used to monitor/control. Furthermore, Liuwei Dihuang Wan (Six-Ingredient Rehmannia Pill) should be supplemented with Deer Antler and Goji Berry, etc., to fill the Kidney Yin in the lower Jiao. When Essence is sufficient, Marrow will naturally be replenished, and there will be no more leakage like a perforated vessel.
