3. Liver Disease Syndrome Differentiation

(1) Liver Qi Stagnation

Bitter taste in the mouth, dry throat, irritability, chest and flank discomfort, and a tense pulse are the basic symptom clusters of this syndrome. If accompanied by abdominal distension, loss of appetite, and nausea, it is liver-stomach disharmony; if accompanied by a lump in the throat that cannot be swallowed or spat out, it is liver qi ascending (Mei He Qi). For liver qi stagnation, the treatment is to soothe the liver and release qi, using Chai Hu Shu Gan San (from "Jingyue Quanshu"); for liver-stomach disharmony, the treatment is to soothe the liver and harmonize the stomach, using Xiao Yao San (from "Jufang"); for liver qi ascending, the treatment is to soothe the liver and lower qi, using Ban Xia Hou Pu Tang (by Zhang Zhongjing). The liver is naturally inclined to flow freely; when it becomes stagnant, it either invades the stomach (liver-stomach disharmony) or rises upward to obstruct the throat (Mei He Qi)—these are the two main manifestations of liver qi stagnation.

(2) Liver-Gallbladder Exuberant Fire

Bitter taste in the mouth, dry throat, irritability, chest and flank discomfort, dizziness, headache, tinnitus, red face and eyes, palpitations and shortness of breath, short and reddish urine, and a tense, rapid pulse. Treatment involves clearing liver fire, using Long Dan Xie Gan Tang (from "Yizong Jinjian"). This syndrome is often caused by long-term stagnation turning into fire, with the basic symptom clusters consisting of two parts:

1. Bitter taste in the mouth, dry throat, irritability, and chest and flank discomfort (liver qi stagnation).
2. Dizziness, headache, red face and eyes, short and reddish urine, and a rapid pulse (fire rising upward).

(3) Liver Yin Deficiency

Dizziness, vertigo, lower back pain, tinnitus, bone-steaming tidal fever, five-heart vexation, night sweats, numbness and tremors in the hands and feet, red tongue with little coating, and a tense, fine pulse. Treatment involves nourishing water and supporting wood, using Qi Ju Di Huang Wan (from "Yiji"). The liver and kidneys share the same origin, and the liver draws nourishment from the kidneys through yin. The manifestations of liver yin deficiency consist of three parts:

1. Dizziness and vertigo, lower back pain and tinnitus (kidney deficiency).
2. Bone-steaming tidal fever, five-heart vexation, and night sweats (yin deficiency).
3. Numbness and tremors in the hands and feet (yin failing to nourish the sinews).

(4) Internal Liver Wind

Clinically, it usually presents in three forms:

1. Extreme Heat Generates Wind (wind-fire interaction): High fever, accompanied by palpitations, convulsions, collapse, and a tense, rapid pulse. Treatment involves draining fire and calming the spirit, using Ling Yang Gou Teng Tang (from "Tongshu Shanghan Lun").
2. Yang Hyperactivity Generates Wind (all sudden, violent stiffness belongs to wind): Mainly manifested as headache, tinnitus, hemiplegia, aphasia, facial asymmetry, convulsions, and coma. Treatment involves calming the liver and extinguishing wind, using Zhen Gan Xi Feng Tang (from "Zhongzhong Canxi Lu").
3. Blood Deficiency Generates Wind (blood failing to nourish the sinews): Mainly manifested as tremors, numbness, convulsions, muscle twitching, etc. Treatment involves nourishing blood and extinguishing wind, using Da Ding Feng Zhu (from "Wenbing Tiaobian").

(5) Cold Stagnation in the Liver Meridian

Lower abdominal pain, contraction of the scrotum, and heavy testicular descent. Treatment involves warming the liver and dispelling cold. Use Nuan Gan Jian (from "Jingyue Quanshu"). The lower abdomen, scrotum, and testicles are all areas traversed by the Foot Jueyin Liver Meridian.
