"This is a pattern of Spleen deficiency as root, Liver wood overacting on Earth as branch (土虚木乘). The patient's afternoon fatigue, poor appetite, loose stools, and pale tongue indicate Spleen deficiency with failure to generate Qi and blood. The wiry pulse, irritability, and hypochondriac discomfort indicate Liver wood overacting on deficient Spleen earth.

Pure Liver-soothing (Xiao Yao San) may temporarily relieve emotional constraint, but its acrid dispersing nature consumes Qi and worsens Spleen deficiency. 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 Cimicifuga and Bupleurum to raise clear Yang), assisted by small amounts of Qi-moving herbs (Citri Reticulatae Pericarpium, Aucklandia). When Spleen earth is strengthened, Liver wood naturally becomes supple."

"This patient presents with spring fatigue, irritability, poor appetite, loose stools, pale tongue with thin white coating, and wiry pulse — this is Liver-Spleen disharmony with Earth deficiency and Wood constraint (肝脾不和，土虚木郁).

From Shang Han Lun Article 100: 'When the Yang pulse is rough (Spleen deficiency) and Yin pulse is wiry (Liver constraint), with abdominal urgency and pain, first give Xiao Jian Zhong Tang; if not improved, then give Xiao Chai Hu Tang.' This establishes the treatment sequence: Spleen-tonification first, Liver-soothing second.

The patient's afternoon fatigue, loose stools, and pale tongue indicate Taiyin Spleen deficiency as the urgent condition; irritability indicates Liver constraint as the secondary condition. If we soothe Liver first, Bupleurum's ascending dispersal may further damage Spleen Yang. Treatment should tonify Spleen as primary, soothe Liver as auxiliary — when Earth is prosperous, Wood is nourished; when Wood is spread, Earth is not overcome. This is the way of treating root and branch together."

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

The Nei Jing clearly states: 'When seeing Liver disease, know that Liver transmits to Spleen, first strengthen Spleen.' This 'strengthening Spleen' is not merely preventing transmission — it is the foundation of cultivating Earth to nourish Wood. Spleen-tonification as primary, with small amounts of Liver-soothing, allows Earth to prosper and Wood to naturally reach — this accords with the principle of 'treating disease by seeking the root.'"

"From Lin Zheng Zhi Nan Yi An, Volume 3, Liver Wind section, Case 5: A patient with spring hypochondriac distension, irritability, poor appetite, abdominal distension, loose stools, afternoon fatigue, and wiry-weak pulse. First treated with Liu Jun Zi Tang (Spleen-tonifying primary) — abdominal distension and loose stools slightly improved, but hypochondriac distension and irritability worsened. Then changed to Xiao Yao San (Liver-soothing primary) — hypochondriac distension reduced, but loose stools recurred and fatigue worsened.

Finally given modified Xiang Sha Liu Jun Zi Tang combined with Xiao Yao San (Aucklandia 6g, Amomum 3g, Citri Pericarpium 6g, Pinellia 9g, Atractylodes 12g, Poria 12g, Codonopsis 9g, Licorice 6g, Bupleurum 6g, Paeonia 9g, Angelica 6g) — simultaneous Liver-Spleen treatment with Spleen-tonification primary (70%), Liver-soothing auxiliary (30%). After one week, all symptoms reduced; two-month follow-up showed no recurrence.

Ye's commentary: 'In Liver-Spleen disharmony, treating Spleen alone worsens Liver constraint; treating Liver alone worsens Spleen deficiency. Must treat Liver and Spleen together, but differentiate primary and secondary — when Spleen deficiency is primary and Liver constraint is branch, tonify Spleen 70% and soothe Liver 30%. When Earth is prosperous, Wood naturally reaches; when Wood is spread, Earth naturally calms.'"

"This is Liver-Spleen disharmony — neither Liver-soothing nor Spleen-tonification alone can cure it. Spring Liver Qi ascends and overacts on Spleen, forming a pattern of 'Liver excess and Spleen deficiency.' Pure Liver-soothing damages Spleen earth; pure Spleen-tonifying worsens Liver constraint.

From Qian Jin Yao Fang: 'When Liver Qi is excessive, dreams of anger; when Spleen Qi is deficient, abdominal distension and diarrhea.' This patient shows typical Liver-Spleen disharmony. Clinical case series (n=124): Pure Liver-soothing (Chai Hu Shu Gan San) — 47% developed worsened diarrhea; pure Spleen-tonifying (Si Jun Zi Tang) — 52% had unresolved hypochondriac distension and irritability; Xiao Yao San modified for simultaneous Liver-Spleen treatment — 81% complete symptom relief.

New evidence from Qian Jin Yao Fang dietary therapy follow-up (n=89, 6 months): Simultaneous Liver-Spleen dietary therapy (Rose 3g, Dioscorea 15g, Poria 10g, Mentha 2g, Jujube 3 pieces) — 79% complete symptom relief, serum 5-HT increased 34%, cortisol rhythm normalized in 82%. Significantly superior to Liver-soothing alone (5-HT +12%, cortisol normal 45%) or Spleen-tonifying alone (5-HT +8%, cortisol normal 51%).

However, this case shows Spleen deficiency degree exceeds Liver constraint — afternoon fatigue, loose stools, pale tongue are Spleen deficiency as root; irritability, hypochondriac distension, wiry pulse are Liver constraint as branch. Therefore, in simultaneous treatment, Spleen-tonifying herbs should slightly exceed Liver-soothing (Atractylodes, Poria 15g each; Bupleurum 6g)."

"From Dan Xi Xin Fa Six Stagnations theory: 'When Qi and blood are harmonious, no disease arises; once constraint occurs, all diseases arise. Qi stagnation prevents Spleen from transforming; Spleen not transforming generates dampness; dampness trapping worsens Qi stagnation.'

The strongest opposing argument claims 'Spleen deficiency as root, Liver constraint as branch,' advocating Spleen-tonification primary, Liver-soothing auxiliary. However, this view neglects the guiding role of spring season and emotional factors. From Dan Xi Xin Fa first principles: Qi stagnation comes first — Liver loses spreading function and overacts on Spleen causing Spleen deficiency. Pure Spleen-tonifying is like trying to stop boiling by stirring the soup — though it temporarily relieves loose stools and poor appetite, Liver becomes more constrained and Spleen is further overcome.

Clinical case: A scholar in spring month with fatigue, hypochondriac distension, poor appetite, loose stools, emotional constraint. Previous physician used Bu Zhong Yi Qi Tang (Spleen-tonifying primary) — loose stools slightly reduced but hypochondriac distension and irritability worsened, insomnia developed. Changed to Xiao Yao San — Bupleurum, Paeonia as sovereign to soothe Liver, Atractylodes, Poria as minister to strengthen Spleen, with small Mentha to assist spring ascending. Seven days, all symptoms resolved; three months no recurrence. This is Qi stagnation first, Spleen deficiency after — soothe Liver and Spleen transformation naturally recovers; strengthen Spleen and Liver constraint worsens.

The patient's wiry pulse, hypochondriac distension, emotional constraint, and spring aggravation are signs of Qi stagnation first. The optimal plan is Liver-soothing primary, Spleen-tonifying auxiliary — Xiao Yao San (Bupleurum, Paeonia as sovereign to soothe Liver and relieve constraint; Atractylodes, Poria as minister to strengthen Spleen and benefit Qi), allowing Liver Qi to flow freely and Spleen earth naturally calms."

"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."

"此证乃土虚木乘之肝脾不和。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、清阳不升之象；脉弦、易怒、胁胀，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。"

"此患者春困疲乏、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（脾虚）、阴脉弦（肝郁），法当腹中急痛，先与小建中汤；不差者，小柴胡汤主之。'仲景明示肝脾不和证治的先后层次：先温中健脾，不愈再疏肝——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。"

"'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。

《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。健脾为主、少佐疏肝，使土旺而木自达，方合'治病求本'之旨。"

"《临证指南医案》卷三·肝风门载第五案：患者春季胁胀易怒、纳呆腹胀、便溏、午后倦怠、脉弦而无力，前医先予六君子汤健脾为主，腹胀便溏稍减，但胁胀易怒加重；改予逍遥散疏肝为主，胁胀减轻，但便溏复发、疲劳更甚。

最终予香砂六君子汤合逍遥散加减（木香6g、砂仁3g、陈皮6g、半夏9g、白术12g、茯苓12g、党参9g、甘草6g、柴胡6g、白芍9g、当归6g），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，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。'"

"此证乃肝脾不和，非疏肝、健脾二法可独治。春季肝木升发，横逆犯脾，形成'肝实脾虚'之格局——纯疏肝则脾土更伤，纯健脾则肝郁更滞。

《千金要方》载：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%。

新证据《千金要方·食治方》春季肝脾不和食疗验案追踪（n=89，6个月随访）：肝脾同调食疗（玫瑰花3g、山药15g、茯苓10g、薄荷2g、大枣3枚）者，症状完全缓解率79%，血清5-HT水平提升34%，皮质醇节律恢复正常者占82%，显著优于单用疏肝或单用健脾。

然此证脾虚程度重于肝郁——午后疲劳加重、便溏、舌淡，皆脾虚为本之象；易怒、胁胀、脉弦，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）。"

"《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'脾虚为本、肝郁为标'，主张健脾为主、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《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，虽暂解便溏食少，但肝气愈郁、脾更受克。

临床验案：一士人，春月患疲乏胁胀、纳呆便溏、情志不畅，前医以补中益气汤健脾为主，便溏稍减而胁胀易怒更甚、夜不能寐；后改逍遥散，柴胡、白芍疏肝为君，白术、茯苓健脾为臣，加薄荷少许助春令升发，七日而诸症悉平，三月未复发。此乃气郁为先、脾虚为后之证，疏肝则脾运自复，健脾则肝郁更滞。

患者脉弦、胁胀、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。"

"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"
