Swollen lymph nodes in the neck are caused by inflammation of the head and facial organs such as the pharyngeal cavity, nose, and eyes, when the lymphatic fluid from the inflamed area converges on the neck, resulting in inflammation and swelling of the lymph nodes in the neck. When the inflammation of the head and facial organs subsides, the inflammation and swelling of the lymph nodes also disappear. The inflammation of the head and facial organs is considered by Chinese medicine to be a fire in the upper jiao, which can be triggered by many factors, such as overwork, staying up late, drinking white wine, eating chili, shabu-shabu lamb, etc. In addition, people with Yin deficiency and fire are more likely to have fire in the upper jiao. If the fire is not relieved for a long time, the enlarged lymph nodes may be mechanized and become solid tumors. People with swollen lymph nodes in the neck are often accompanied by dry mouth and lips, sore throat or throat discomfort, unilateral or bilateral pain in the neck, swelling, and increased eye stools. For patients with Yin deficiency and fire, using only antibacterial anti-inflammatory drugs is like shaking a fan in a sauna to keep cool, which is not helpful. Therefore, the best and the only treatment method is Chinese medicine. In other words, through the diagnosis of Chinese medicine, herbs that cool the blood and invigorate it, nourish Yin and detoxify it can be cured quickly. Not only will the lump in the neck shrink quickly and the lymph node inflammation subside, but your usual symptoms of dry throat, blurred vision and sleeplessness will also be relieved quickly. The reason for this is that your Yin deficiency and fire constitution has been corrected. This is the usual saying that you should treat the root of the disease and clear the fire!
