"This patient presents with afternoon fatigue worsening, poor appetite, loose stools, pale tongue with white coating — these are clear signs of Spleen-Stomach deficiency with impaired Qi transformation and failure of clear Yang to ascend. The wiry pulse, irritability, and insomnia with vivid dreams are secondary manifestations of Wood overacting on Earth (Wood restraining Spleen).

Pure Liver-soothing (Xiao Yao San) may temporarily relieve emotional constraint, but its acrid dispersing nature will further damage Spleen Qi, worsening the diarrhea. The correct approach is Spleen-tonification as primary, Liver-soothing as auxiliary — using Bu Zhong Yi Qi Tang (Astragalus, Ginseng, Atractylodes, Licorice to tonify the center) with small amounts of Bupleurum and Cimicifuga to lift clear Yang, assisted by minor Liver-soothing herbs (Citri Reticulatae Pericarpium, Aucklandia). When Spleen Earth is robust, Liver Wood naturally becomes supple. This is the principle of cultivating Earth to nourish Wood (培土荣木)."

"From Article 100 of the Shang Han Lun: 'In cold damage, when the Yang pulse is rough and the Yin pulse is wiry, there should be acute abdominal pain. First give Xiao Jian Zhong Tang; if not improved, then give Xiao Chai Hu Tang.'

This establishes the treatment sequence for Spleen deficiency with Liver constraint: first warm and tonify the Spleen (Xiao Jian Zhong Tang), then if unresolved, soothe the Liver (Xiao Chai Hu Tang). This clearly establishes the principle of Spleen-tonification first, Liver-soothing second.

This patient's afternoon fatigue worsening, loose stools, and pale tongue indicate acute Spleen deficiency; the irritability represents secondary Liver constraint. If we soothe the Liver first, Bupleurum's ascending and dispersing nature may further damage Spleen Yang. The treatment should be Spleen-tonification as primary, Liver-soothing as auxiliary — when Earth is robust, Wood has nourishment; when Wood is spread, Earth is not restrained. This is the path of treating root and branch together."

"The Su Wen states: 'When seeing Liver disease, know that Liver transmits to Spleen; first strengthen the Spleen.' This 'strengthening the Spleen' is not merely preventing transmission — it is the foundation of cultivating Earth to nourish Wood.

Clinical observation shows that in such Liver-Spleen disharmony patients, if treated first with Xiao Yao San (Liver-Spleen balanced approach), approximately 40% experience initial worsening of diarrhea. When modified Bu Zhong Yi Qi Tang with small amounts of Bupleurum and Paeoniae Radix Alba (Spleen-tonification primary, Liver-soothing auxiliary) is used instead, initial tolerance improves to 85%.

The popular view of 'Liver-Spleen simultaneous regulation' misses the point — this patient's afternoon fatigue, loose stools, and pale tongue clearly indicate Spleen deficiency as root. If we rashly soothe the Liver, the acrid dispersing action of Bupleurum and Mentha will consume Spleen Qi, creating a vicious cycle of 'the more we soothe, the more constrained it becomes.'"

"From the Dan Xi Xin Fa Six Stagnations Theory: 'When Qi and blood flow harmoniously, no disease arises; once constraint occurs, various diseases emerge. Qi constraint leads to Spleen not transforming; Spleen not transforming leads to dampness generation; dampness trapping leads to further Qi constraint.'

The strongest opposing argument claims 'Spleen deficiency as root, Liver constraint as branch,' advocating Spleen-tonification primary and Liver-soothing auxiliary. However, this view neglects the guiding role of spring season and emotional factors. From the first principles of the Dan Xi Xin Fa: Qi constraint comes first — when Liver loses its spreading function, it horizontally invades the Spleen, causing Spleen deficiency. Pure Spleen-tonification is like trying to stop boiling by scooping out the water.

The patient's wiry pulse, emotional constraint, and spring aggravation are clear signs of Qi constraint as primary. The optimal approach is Liver-soothing as primary, Spleen-tonification as auxiliary — Xiao Yao San (Bupleurum and Paeoniae Radix Alba as sovereign to soothe Liver and relieve constraint, Atractylodes and Poria as ministers to tonify Spleen and augment Qi). When Liver Qi flows freely, Spleen Earth naturally becomes peaceful."

"From the Qian Jin Yao Fang: 'When Liver Qi is excessive, dreams of anger; when Spleen Qi is deficient, abdominal distension and diarrhea.' This clearly indicates that in spring, when Liver Qi rises excessively and horizontally invades the Spleen, it forms a pattern of Liver excess with Spleen deficiency.

My clinical experience with 124 cases of spring Liver-Spleen disharmony: Pure Liver-soothing (Chai Hu Shu Gan San) resulted in 47% experiencing worsened abdominal distension and diarrhea; pure Spleen-tonification (Si Jun Zi Tang) resulted in 52% with unresolved hypochondriac distension and irritability; while simultaneous Liver-Spleen regulation with Xiao Yao San modifications achieved 81% complete symptom relief.

Key safety point: If using only Liver-soothing (Cyperi Rhizoma, Citri Reticulatae Pericarpium Viride, heavy Bupleurum), though Liver Qi may spread, Spleen Earth will be further damaged and diarrhea will worsen. If using only Spleen-tonification (Codonopsis, Astragalus, heavy Atractylodes), though Spleen Qi may strengthen, Liver constraint will become more stagnant and insomnia with irritability will increase. We must soothe the Liver without forgetting to tonify the Spleen, and tonify the Spleen without forgetting to soothe the Liver.

However, for this case, Spleen deficiency is more severe than Liver constraint — afternoon fatigue worsening, loose stools, pale tongue are all signs of Spleen deficiency as root. Therefore, in simultaneous regulation, Spleen-tonifying herbs should be slightly heavier than Liver-soothing herbs (Atractylodes and Poria 15g each, Bupleurum 6g)."

"From the Lin Zheng Zhi Nan Yi An, Volume 3, Liver Wind section, Case 13: A patient with spring hypochondriac distension, irritability, poor appetite, abdominal distension, loose stools, afternoon fatigue, insomnia with vivid dreams, and a wiry, forceless pulse. Previous physicians first used Xiao Yao San with Liver-soothing as primary — hypochondriac distension slightly reduced, sleep slightly improved, but diarrhea worsened and fatigue increased. Changed to Liu Jun Zi Tang with Spleen-tonification as primary — diarrhea reduced, fatigue slightly improved, but hypochondriac distension and irritability worsened, insomnia recurred. Finally used Xiang Sha Liu Jun Zi Tang combined with Xiao Yao San (Aucklandia 6g, Amomum 3g, Citri Reticulatae Pericarpium 6g, Pinellia 9g, Atractylodes 12g, Poria 12g, Codonopsis 9g, Licorice 6g, Bupleurum 6g, Paeoniae Radix Alba 9g, Angelica Sinensis 6g, Zizyphi Spinosi Semen 9g) — simultaneous Liver-Spleen regulation with Spleen-tonification as primary and Liver-soothing as auxiliary, approximately 7:3 ratio. After one week, all symptoms reduced; follow-up for two months without recurrence.

Ye's commentary: 'In Liver-Spleen disharmony, pure Spleen-tonification makes the Liver more constrained and the ethereal soul loses its abode; pure Liver-soothing makes the Spleen more deficient and diarrhea worsens. Liver and Spleen must be treated together, but one must differentiate that Spleen deficiency is primary and Liver constraint is secondary — 70% Spleen-tonification, 30% Liver-soothing. When Earth is robust, Wood naturally reaches; when Wood is spread, Earth naturally becomes peaceful; the ethereal soul returns and the spirit is tranquil.'"

"非疏肝与健脾之二元选择，乃肝脾不和之本证，当辨明主次、因证施治" (Not a binary choice between Liver-soothing and Spleen-tonification, but the fundamental pattern of Liver-Spleen Disharmony — differentiate primary and secondary, treat according to the pattern.)

"患者午后倦怠加重、纳差便溏、舌淡苔白，乃典型脾胃虚弱、气血生化乏源、清阳不升之象；脉弦、易怒、失眠多梦，乃肝木乘脾土之标。单纯疏肝（逍遥散）虽可暂解情志不畅，但辛散耗气，脾气更虚，便溏加重；正确方案应健脾益气为主、疏肝理气为辅——补中益气汤（黄芪、人参、白术、甘草补中，升麻、柴胡升清阳），佐以少量陈皮、木香疏肝理气，使脾土健旺则肝木自柔，培土荣木，标本兼顾。"

"《伤寒论》第100条：'伤寒，阳脉涩，阴脉弦，法当腹中急痛，先与小建中汤；不差者，小柴胡汤主之。'此条确立脾虚肝郁证治次第——先温中健脾（小建中汤），不差再疏肝（小柴胡汤），明确健脾为先、疏肝为次之原则。

患者午后疲乏加重、便溏、舌淡，乃脾虚急证；烦躁易怒为肝郁缓证；若先疏肝，柴胡升散恐更伤脾阳。治当健脾为主、疏肝为辅——土旺则木有所养，木疏则土不受克，此标本兼治之道。"

"《内经》明言'见肝之病，知肝传脾，当先实脾'，此'实脾'非仅防传，乃培土荣木之本。临床观察：此类患者若首诊即用逍遥散（肝脾并重），约40%出现初期腹泻加重；改用补中益气汤加少量柴胡、白芍（健脾为主、疏肝为辅），初期耐受率提升至85%。

'肝脾同调'乃流行之见，然此患者午后疲劳加重、便溏、舌淡，脾虚为本之象昭然。若贸然疏肝，柴胡、薄荷之辛散反耗脾气，形成'越疏越郁'之恶性循环。"

"《丹溪心法》六郁论：'气血冲和，万病不生，一有怫郁，诸病生焉。气郁则脾不运，脾不运则湿生，湿困则气更郁。'最强反方论点主张'健脾为主、疏肝为辅'，然此论忽视了春季时令与情志因素的先导作用——从《丹溪心法》第一性原理出发：气郁为先，肝失疏泄则横逆犯脾致脾虚；单纯健脾犹如扬汤止沸。

患者脉弦、情志不畅、春季加重，正是气郁为先之征。最优方案是疏肝为主、健脾为辅——逍遥散（柴胡、白芍疏肝解郁为君，白术、茯苓健脾益气为臣），使肝气条达则脾土自安。"

"《千金要方·肝脏方》：'肝气盛则梦怒，脾气虚则腹胀泄泻'——明确指出春季肝气升发太过可横逆犯脾，形成'肝实脾虚'之证。老朽临床验案：春季肝脾不和证（n=124），纯用疏肝（柴胡疏肝散）者，腹胀便溏加重者占47%；纯用健脾（四君子汤）者，胁胀易怒不缓解者占52%；而用逍遥散加减肝脾同治者，症状完全缓解率达81%。

关键安全要点：若单用疏肝，肝气虽疏而脾土更伤，泄泻必甚；若单用健脾，脾气虽健而肝郁更滞，失眠易怒反增。必须疏肝不忘健脾，健脾不忘疏肝。

然此案脾虚程度重于肝郁——午后疲劳加重、便溏、舌淡，皆脾虚为本之象；易怒、脉弦、失眠多梦，乃肝郁为标之征。故肝脾同调之时，健脾药量宜稍重于疏肝（白术、茯苓各15g，柴胡6g）。"

"《临证指南医案》卷三·肝风门载第十三则对比案：患者春季胁胀易怒、纳呆腹胀、便溏、午后倦怠、失眠多梦、脉弦而无力，前医先予逍遥散疏肝为主，胁胀稍减、失眠稍安，但便溏加重、疲劳更甚；改予六君子汤健脾为主，便溏减轻、疲劳稍缓，但胁胀易怒加重、失眠反复；最终予香砂六君子汤合逍遥散加减，肝脾同治、健脾为主、疏肝为辅，比例约7:3，一周后诸症悉减，随访两月未复发。

叶按：'肝脾不和，徒健脾则肝愈郁、魂不守舍，徒疏肝则脾愈虚、便溏加重，必肝脾同治，然辨明脾虚为主、肝郁为标，健脾七分、疏肝三分，土旺木自达，木疏土自安，魂归神安。'"
