3. Liver Disease Pattern Differentiation

(1) Liver-Qi Stagnation

Bitter taste in the mouth, dry throat, irritability, fullness and discomfort in the chest and flanks, and a taut pulse are the basic symptom cluster of this syndrome. If accompanied by abdominal distension, loss of appetite, and nausea, it is liver-stomach disharmony; if accompanied by something stuck in the throat that cannot be swallowed or expelled, it is liver qi ascending (meihe qi). Treatment for liver qi stagnation is to soothe the liver and resolve stagnation, using Chai Hu Shu Gan San (from "Jingyue Quanshu"); for liver-stomach disharmony, it is recommended to soothe the liver and harmonize the stomach, using Xiao Yao San (from "Jufang"); for liver qi ascending, it is recommended to soothe the liver and lower qi, using Ban Xia Hou Pu Tang (by Zhang Zhongjing). The liver is naturally open and unimpeded; when it becomes stagnant, it rebels against the stomach (liver-stomach disharmony) as the first manifestation; when it ascends and attacks the throat (meihe qi), it is the second manifestation. Both are products of liver qi stagnation.

(2) Liver-Gallbladder Excess Fire

Bitter taste in the mouth, dry throat, irritability, fullness and discomfort in the chest and flanks, dizziness and headache, tinnitus and red eyes, palpitations and rapid breathing, short and red urine, and a taut, 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, and its basic symptom cluster consists of two parts: ① bitter taste in the mouth, dry throat, irritability, and fullness and discomfort in the chest and flanks (liver qi stagnation). ② dizziness, headache, facial flushing, red eyes, short and red urine, and a rapid pulse (fire rising upward).

(3) Liver-Yin Deficiency

Dizziness, vertigo, lower back pain, tinnitus, bone-steaming heat, five-heart heat, night sweats, numbness and tremors in the hands and feet, red tongue with little coating, and a taut, fine pulse—treatment involves nourishing water and nurturing wood, using Qi Ju Di Huang Wan (from "Yiji"). The liver and kidneys share the same origin; liver yin draws nourishment from kidney yin, so the manifestations of liver yin deficiency consist of three parts: ① dizziness and vertigo, lower back pain and tinnitus (kidney deficiency). ② bone-steaming heat, five-heart heat, and night sweats (yin deficiency). ③ numbness and tremors in the hands and feet (yin not nourishing the tendons).

(4) Internal Liver Wind

Clinically, it usually presents in three scenarios: ① extreme heat generating wind (wind-fire interaction): symptoms include high fever, accompanied by palpitations, convulsions, syncope, and a taut, rapid pulse—treatment involves purging fire and calming the spirit, using Ling Yang Gou Teng Tang (from "Tongsu Shanghan Lun"). ② yang excess generating wind (all sudden rigidity belongs to wind): main manifestations include headache, tinnitus, hemiplegia, aphasia, facial and oral 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 generating wind (blood not nourishing the tendons): main clinical manifestations include 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 testicles—treatment involves warming the liver and dispersing cold, using Nuan Gan Jian (from "Jingyue Quanshu"). The lower abdomen, scrotum, and testicles are all areas traversed by the Foot Jueyin Liver Meridian.
