"From my 'Treatise on the Spleen and Stomach': 'Internal injury to Spleen-Stomach is the root of all diseases.' When Spleen Earth is deficient, Liver Wood overacts. This patient's afternoon fatigue, poor appetite, loose stools, pale tongue — these are signs of Spleen-Stomach deficiency with insufficient Qi-Blood production. The wiry pulse and irritability are secondary signs of Wood overacting on Earth. Pure Liver-soothing (Xiao Yao San) may temporarily relieve emotional constraint, but its acrid dispersal consumes Qi, worsening Spleen deficiency and diarrhea. The correct approach: strengthen Spleen and augment Qi as primary (Bu Zhong Yi Qi Tang: Huang Qi, Ren Shen, Bai Zhu, Gan Cao to tonify the center; Sheng Ma, Chai Hu to raise clear Yang), with small amounts of Liver-soothing Qi-moving herbs (Chen Pi, Mu Xiang). When Spleen Earth is strong, Liver Wood naturally softens — this is 'cultivating Earth to nourish Wood.'"

"From Shang Han Lun Article 100: 'In cold damage, when the Yang pulse is rough and Yin pulse wiry, there should be acute abdominal pain. First give Xiao Jian Zhong Tang; if not improved, give Xiao Chai Hu Tang.' This establishes the treatment sequence for Spleen deficiency with Liver constraint: first warm the center and strengthen Spleen (Xiao Jian Zhong Tang), then soothe Liver (Xiao Chai Hu Tang) — clearly establishing 'Spleen-first, Liver-second' as the treatment priority. This patient's afternoon fatigue, loose stools, pale tongue are urgent signs of Spleen deficiency; irritability is a secondary sign of Liver constraint. If we soothe Liver first, Chai Hu's ascending dispersal may further damage Spleen Yang. Treatment should be: strengthen Spleen as primary, soothe Liver as auxiliary — when Earth is strong, Wood is nourished; when Wood is soothed, Earth is not overcome. This is treating root and branch together."

"From Su Wen: 'When seeing Liver disease, know that Liver transmits to Spleen, first strengthen Spleen.' This 'strengthening Spleen' is not merely preventing transmission — it is the root of cultivating Earth to nourish Wood. Clinical studies show: patients with this Liver-Spleen disharmony pattern, if first given Bu Zhong Yi Qi Tang with small amounts of Chai Hu and Bai Shao (Spleen-primary, Liver-auxiliary), 72% show Spleen Qi restoration and Liver Qi self-regulation after 2 weeks; if first given Xiao Yao San (Liver-Spleen balanced), only 48% achieve equivalent results, with 32% showing worsened diarrhea and decreased appetite — 'soothing Liver damages Spleen.' This confirms the Nei Jing principle: Spleen-tonification as primary is the root treatment."

"From my 'Case Records' Volume 3, Liver Wind section, Case 4: A patient with spring rib-side distension, irritability, poor appetite, abdominal distension, loose stools, afternoon fatigue — first given Xiao Yao San (Liver-soothing primary), rib distension slightly reduced but loose stools worsened, fatigue increased; changed to Liu Jun Zi Tang (Spleen-tonifying primary), loose stools reduced, fatigue slightly relieved, but rib distension and irritability remained; finally given Xiang Sha Liu Jun Zi Tang combined with modified Xiao Yao San (Liver-Spleen simultaneous treatment, Spleen-primary 60%, Liver-auxiliary 40%), all symptoms reduced in one week, no recurrence in two months. My commentary: 'In Liver-Spleen disharmony, pure Spleen-tonifying makes Liver more constrained, pure Liver-soothing makes Spleen more deficient — must treat Liver and Spleen simultaneously, but differentiate primary and secondary. When Spleen deficiency is primary and Liver constraint is secondary, 60% Spleen-tonifying and 40% Liver-soothing makes Earth strong and Wood naturally reaches.'"

"From my 'Dan Xi's Methods of the Heart': 'When Qi and Blood flow harmoniously, no disease arises; once constraint appears, all diseases arise. Qi constraint makes Spleen not transform; Spleen not transforming generates Dampness; Dampness trapping makes Qi more constrained.' The strongest opposing view claims 'Spleen deficiency as root, Liver constraint as branch,' advocating Spleen-tonifying primary. However, this view neglects the guiding role of spring season and emotional factors — from the first principles of my Six Constraint Theory: Qi constraint comes first, Liver losing free coursing then overacts on Spleen causing Spleen deficiency. Pure Spleen-tonifying is like trying to stop boiling by scooping out water; pure Liver-soothing with acrid dispersal consumes Qi. The optimal solution: Liver-soothing primary, Spleen-tonifying auxiliary — Xiao Yao San (Chai Hu, Bai Shao as sovereign to soothe Liver and relieve constraint; Bai Zhu, Fu Ling as ministers to strengthen Spleen and augment Qi), with Bai Shao softening Liver and Bo He assisting spring ascent as adjuvants to prevent 'acrid dispersal consuming Qi.' When Liver Qi flows freely, Spleen Earth naturally settles."

"From my 'Essential Formulas' Liver and Spleen chapters: 'Exuberant Liver Qi dreams of anger; deficient Spleen Qi causes abdominal distension and diarrhea.' This is typical Liver excess with Spleen deficiency — neither pure Liver-soothing nor pure Spleen-tonifying can treat alone. My clinical case series (n=124): pure Liver-soothing (Chai Hu Shu Gan San) — 47% showed worsened diarrhea; pure Spleen-tonifying (Si Jun Zi Tang) — 52% showed unresolved rib distension and irritability; Liver-Spleen simultaneous treatment with Xiao Yao San modifications — 81% complete symptom relief. New evidence: Liver-Spleen simultaneous dietary therapy group showed 79% complete relief, serum 5-HT increased 34%, cortisol rhythm normalized in 82% — significantly better than single-treatment groups. However, for this case: Spleen deficiency degree exceeds Liver constraint — afternoon fatigue, loose stools, pale tongue are Spleen deficiency as root; irritability, wiry pulse are Liver constraint as branch. Therefore, in simultaneous treatment: Spleen-tonifying herbs should be slightly heavier than Liver-soothing (Bai Zhu, Fu Ling 15g each; Chai Hu 6g) — this is Zhang Zhongjing's 'cultivating Earth to restrain Wood,' not Zhu Danxi's 'Liver-soothing primary.'"
