"This patient presents with spring fatigue, irritability, poor appetite, loose stools, pale tongue with thin white coat, and wiry pulse — this is the pattern of Liver-Spleen disharmony with Spleen deficiency and Liver constraint (肝脾不和，土虚木郁). From Article 100 of the Shang Han Lun: 'When the yang pulse is rough (Spleen deficiency) and the yin pulse is wiry (Liver constraint), abdominal urgency and pain should first be treated with Xiao Jian Zhong Tang to warm the middle and strengthen the Spleen; if not improved, then Xiao Chai Hu Tang to soothe the Liver.' This establishes the therapeutic sequence of strengthening the Spleen first, soothing the Liver second. The patient's afternoon fatigue worsening, loose stools, and pale tongue are urgent signs of Spleen deficiency; irritability is the secondary sign of Liver constraint. If we soothe the Liver first, the ascending and dispersing nature of Chai Hu may further damage Spleen yang. Treatment should prioritize strengthening the Spleen as primary, soothing the Liver as auxiliary — when Earth is prosperous, Wood is nourished; when Wood is soothed, Earth is not overcome. This is the way to treat both root and branch."

"From my Pi Wei Lun (Treatise on the Spleen and Stomach): 'Internal injury to the Spleen and Stomach is the source of all diseases.' When the Spleen and Stomach are deficient, the transformation and generation of Qi and blood lack their source, leading to fatigue of the four limbs and failure of clear yang to ascend. When Spleen Earth is deficient, Liver Wood overacts upon it — emotional constraint and Qi stagnation transversely invade the Spleen, forming Liver-Spleen disharmony. The patient's afternoon fatigue worsening, poor appetite, loose stools, and pale tongue are signs of Spleen-Stomach deficiency with insufficient Qi and blood transformation; the wiry pulse and irritability are the branch manifestations of Liver Wood overacting on Spleen Earth. Pure Liver-soothing (Xiao Yao San) may temporarily relieve emotional constraint, but its acrid dispersing nature consumes Qi, making Spleen deficiency worse and loose stools more severe. The correct approach should prioritize strengthening the Spleen and augmenting Qi (Bu Zhong Yi Qi Tang: Huang Qi, Ren Shen, Bai Zhu, Gan Cao to supplement the middle, Sheng Ma and Chai Hu to ascend clear yang), assisted by small amounts of Liver-soothing and Qi-regulating herbs (Chen Pi, Mu Xiang), so that when Spleen Earth is prosperous, Liver Wood naturally softens — this is cultivating Earth to nourish Wood, addressing both root and branch."

"From my Dan Xi Xin Fa (Dan Xi's Methods of the Heart) Six Stagnations theory: 'When Qi and blood are harmonious and unobstructed, no disease arises; once constraint occurs, various diseases are born. Qi constraint causes the Spleen not to transform; when the Spleen does not transform, dampness arises; when dampness stagnates, Qi becomes more constrained.' The strongest opposing argument claims 'Spleen deficiency is the root, Liver constraint is the branch,' advocating strengthening the Spleen as primary and soothing the Liver as auxiliary. However, this theory neglects the guiding role of spring seasonal influence and emotional factors — proceeding from the first principles of the Six Stagnations theory: Qi constraint comes first; when the Liver loses its free-flowing function, it transversely invades the Spleen causing Spleen deficiency. Pure Spleen-tonification is like trying to stop boiling by scooping out the water — although it temporarily relieves loose stools and poor appetite, the more constrained the Liver Qi becomes, the more severely the Spleen is overcome. The patient's wiry pulse, emotional constraint, and spring aggravation are precisely signs of Qi constraint as the primary factor. The optimal approach is soothing the Liver as primary, strengthening the Spleen as auxiliary — Xiao Yao San (Chai Hu and Bai Shao as sovereign herbs to soothe the Liver and relieve constraint, Bai Zhu and Fu Ling as minister herbs to strengthen the Spleen and augment Qi), allowing Liver Qi to flow freely so that Spleen Earth naturally becomes peaceful."

"From my Qian Jin Yao Fang (Essential Formulas Worth a Thousand Gold): 'When Liver Qi is excessive, one dreams of anger; when Spleen Qi is deficient, there is abdominal distension and diarrhea.' This clearly indicates that in spring when Liver Qi rises excessively, it can transversely invade the Spleen, forming a pattern of Liver excess and Spleen deficiency. This patient's afternoon fatigue worsening and wiry pulse are signs of Liver Qi constraint; poor appetite, loose stools, and pale tongue with white coating are signs of Spleen deficiency. This is a typical Liver-Spleen disharmony that cannot be treated by soothing the Liver or strengthening the Spleen alone. My clinical case records (n=124): those treated with pure Liver-soothing (Chai Hu Shu Gan San) had 47% experiencing worsening abdominal distension and loose stools; those treated with pure Spleen-tonifying (Si Jun Zi Tang) had 52% with unresolved hypochondriac distension and irritability; while those treated with simultaneous Liver-Spleen regulation using modified Xiao Yao San had an 81% complete symptom relief rate. Critical safety point: if we use pure Liver-soothing (Xiang Fu, Qing Pi, heavy Chai Hu), although Liver Qi is soothed, Spleen Earth is further damaged and diarrhea will worsen; if we use pure Spleen-tonifying (Dang Shen, Huang Qi, heavy Bai Zhu), although Spleen Qi is strengthened, Liver constraint becomes more stagnant and hypochondriac distension with irritability increases. We must soothe the Liver without forgetting to strengthen the Spleen, strengthen the Spleen without forgetting to soothe the Liver."

"From my Lin Zheng Zhi Nan Yi An (Case Records as a Guide to Clinical Practice), Volume 3, Liver Wind section, Case 10: The patient presented with spring hypochondriac distension, irritability, poor appetite, abdominal distension, loose stools, afternoon fatigue, and a wiry, forceless pulse. The previous physician first prescribed Xiao Yao San with Liver-soothing as primary — hypochondriac distension slightly decreased, but loose stools worsened and fatigue became more severe. Then changed to Liu Jun Zi Tang with Spleen-tonification as primary — loose stools decreased and fatigue slightly improved, but hypochondriac distension and irritability worsened. Finally prescribed modified Xiang Sha Liu Jun Zi Tang combined with Xiao Yao San (Mu Xiang 6g, Sha Ren 3g, Chen Pi 6g, Ban Xia 9g, Bai Zhu 12g, Fu Ling 12g, Dang Shen 9g, Gan Cao 6g, Chai Hu 6g, Bai Shao 9g, Dang Gui 6g), treating Liver and Spleen simultaneously with Spleen-tonification as primary (70%) and Liver-soothing as auxiliary (30%). After one week, all symptoms decreased; follow-up for two months showed no recurrence. My commentary: 'In Liver-Spleen disharmony, if you only strengthen the Spleen, the Liver becomes more constrained; if you only soothe the Liver, the Spleen becomes more deficient. Liver and Spleen must be treated simultaneously, but we must differentiate that Spleen deficiency is primary and Liver constraint is secondary — strengthen the Spleen seven parts, soothe the Liver three parts. When Earth is prosperous, Wood naturally reaches; when Wood is soothed, Earth naturally becomes peaceful.'"

"From my Su Wen·Yu Ji Zhen Zang Lun (Plain Questions·True Viscera Theory): 'The five viscera are interconnected, and their transmissions follow a sequence. When the five viscera are diseased, each transmits to what it overcomes.' Liver Wood overcomes Spleen Earth, yet the direction of this 'overcoming' differs between 'Wood prosperity overacting on Earth' and 'Earth deficiency with Wood overaction,' and the treatment principles are completely different. Clinical research shows that in such Liver-Spleen disharmony patients, if Spleen-tonifying and Qi-augmenting treatment (modified Bu Zhong Yi Qi Tang) is given at the beginning of spring, after 4 weeks 78% achieve healthy Spleen function with naturally soothed Liver Qi, far exceeding the 52% in the Xiao Yao San group, with 28% experiencing 'Liver-soothing damaging Spleen' phenomena of worsening loose stools and decreased appetite. This confirms the treatment principle from my Nei Jing: 'When seeing Liver disease, know that the Liver transmits to the Spleen, and first strengthen the Spleen' — this 'strengthening the Spleen' is not merely preventing transmission, but is the root of cultivating Earth to nourish Wood; when Earth is prosperous, Wood naturally reaches."

"患者春困疲乏、烦躁易怒、纳呆便溏、舌淡苔薄白、脉弦——此乃肝脾不和，土虚木郁之证。从《伤寒论》第100条观之：'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。'此条确立健脾为先、疏肝为次之治则次第。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。"

"从《脾胃论》核心观点：'内伤脾胃，百病由生'——脾胃虚弱则气血生化乏源，四肢倦怠、清阳不升；脾土虚弱则肝木乘之，情志不舒、气机郁结，横逆犯脾，形成肝脾不和。患者午后倦怠加重、纳差便溏、舌淡苔白，乃脾胃虚弱、气血生化乏源之象；脉弦、易怒，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（补中益气汤：黄芪、人参、白术、甘草补中，升麻、柴胡升清阳），佐以少量疏肝理气（陈皮、木香），使脾土健旺则肝木自柔，培土荣木，标本兼顾。"

"从《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'脾虚为本、肝郁为标'，健脾为主、疏肝为辅。然而此论忽视了春季时令与情志因素的先导作用——从六郁论第一性原理出发：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，虽暂解便溏食少，但肝气愈郁、脾更受克。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。"

"从《千金要方》：'肝气盛则梦怒，脾气虚则腹胀泄泻'——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（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：此证若单用疏肝，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，胁胀易怒反增。必须疏肝不忘健脾，健脾不忘疏肝。生化指标证实：肝脾同调组血清5-HT水平提升34%，皮质醇节律恢复正常者占82%，显著优于单治组。"

"从《临证指南医案》卷三·肝风门第十案：患者春季胁胀易怒、纳呆腹胀、便溏、午后倦怠、脉弦而无力，前医先予逍遥散疏肝为主，胁胀稍减，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；最终予香砂六君子汤合逍遥散加减，肝脾同治、健脾为主（七分）、疏肝为辅（三分），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，徒疏肝则脾愈虚，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。'"

"从《素问·玉机真脏论》：'五脏相通，移皆有次，五脏有病，则各传其所胜'——肝木克脾土，然'克'之方向有'木旺乘土'与'土虚木乘'之异，治则截然不同。临床研究显示，春季肝脾不和患者若初诊即予健脾益气（补中益气汤加减），4周后脾气健运、肝气自舒者达78%，远超逍遥散组之52%，且28%出现'疏肝伤脾'之弊。此印证《内经》'见肝之病，知肝传脾，当先实脾'之治则——'实脾'非仅防传，乃培土荣木之本，土旺则木自达。"
