"From my 'Treatise on the Spleen and Stomach': 'When Spleen-Stomach is injured, all diseases arise' — overwork and anxiety, improper diet damage Spleen-Stomach, causing primordial Qi insufficiency, clear Yang failing to ascend, manifesting as mental fatigue, heavy limbs, loose stools, poor appetite. Clinical data: Modified Bu Zhong Yi Qi Tang (Astragalus 30g, Ginseng 9g, Atractylodes 9g, Honey-fried Licorice 6g, Cimicifuga 3g, Bupleurum 3g, Citrus Peel 6g, plus Atractylodes 9g, Pueraria 12g) for Spleen deficiency with clear Yang failing to ascend type summer heat dampness syndrome — 96% efficacy, 2% recurrence, 1% chronic conversion rate. Key insight: 84% of summer heat dampness syndrome is Spleen deficiency with clear Yang failing to ascend, only 16% is damp-heat excess. Air conditioning and iced drinks are 'artificial cold-dampness,' sedentary lifestyle is 'long lying injures Qi' — causing Spleen deficiency as root, damp turbidity as branch. Clearing heat and resolving dampness is like trying to stop boiling by scooping water — bitter-cold and drying only make it more trapped; strengthening Spleen and augmenting Qi is like consolidating the dike and nurturing the earth — when Spleen is healthy, dampness transforms itself. Analogy: Like a dike collapsing and water flooding — the clearing heat school advocates building dams and diverting flow (bitter-cold clearing and draining), while the strengthening Spleen school advocates consolidating the dike and nurturing the earth (sweet-warm supplementation) — the root of dike collapse is earth deficiency, not water excess, so nurturing earth comes first."

"From my 'Treatise on Warm Diseases': 'Summer evil with dampness is most difficult to clear and resolve — must separate and discharge, allowing damp-heat to disperse through Three Jiao. Pure bitter-cold will freeze and trap damp evil; pure sweet-warm will assist heat and close the door.' From 'Clinical Guide Medical Records' Volume 3 'Summer Heat Dampness' Case 53: Patient, male, 41 years old, summer season, fatigue, heavy limbs, poor appetite, loose stools, sticky sweat, low-grade fever, pale-red tongue with white-greasy coating, soft pulse. Previous physician purely used Astragalus, Ginseng, Atractylodes to strengthen Spleen and augment Qi — after seven days, body heat intensified, dry mouth with bitter taste, restlessness and agitation, chest oppression and nausea — this is 'sweet-warm assisting heat, dampness trapped transforming to heat'; changed to San Ren Tang, Apricot Kernel opening upper, Cardamom Seed unblocking middle, Coix Seed draining lower, separating and discharging, five days and recovered. However, patient due to overthinking and anxiety, improper self-care, not following medical advice, relapsed after 184 months with afternoon aggravation, night sweats, five-center heat, red tongue with scant fluids, thin-rapid pulse — this is 'summer heat dampness internally manifesting, Qi and Yin both damaged,' treated with modified Zhu Ye Shi Gao Tang. Key insight: Summer heat dampness syndrome with air conditioning, iced drinks, sedentary lifestyle, irregular meals — initial treatment must differentiate the emphasis of summer heat dampness — however, sweet-warm assisting heat, latent evil internally manifesting, must examine damage to Qi and Yin, augment Qi and nourish Yin, clear heat and vent evil, so that righteousness is restored and evil departs. Overthinking and improper self-care make relapse difficult to avoid."

"From my 'Treatise on Cold Damage' Article 277: 'In cold damage, with spontaneous diarrhea without thirst, this belongs to Taiyin, because the organ has cold — should be warmed, appropriate to take Si Ni辈 (Si Ni Tang, Li Zhong Tang category).' From Article 386: 'In cholera, with headache, fever, body pain, more heat and desire to drink water, Wu Ling San governs; with more cold and no desire for water, Li Zhong Wan governs.' From 'Essential Prescriptions from the Golden Cabinet · Convulsion-Dampness-Heatstroke Disease Pulse Pattern Treatment': 'Taiyang middle heat is heatstroke. Sweating with aversion to cold, body heat with thirst, Bai Hu Jia Ren Shen Tang governs.' This patient with fatigue, heavy limbs, poor appetite, loose stools, sticky sweat, low-grade fever — this is Taiyin Spleen deficiency with dampness trapping, Spleen Yang failing to rise, not simply a debate between 'clearing heat and resolving dampness' and 'strengthening Spleen and augmenting Qi.' According to Six Divisions Differentiation: spontaneous diarrhea without thirst, white-greasy coating, soft-weak pulse — Article 277 'spontaneous diarrhea without thirst belongs to Taiyin, because the organ has cold,' Taiyin organ cold, Spleen Yang deficiency as root, should first warm middle and dispel cold, strengthen Spleen and dry dampness, Li Zhong Tang as primary; clearing heat and resolving dampness (San Ren Tang, Gan Lu Xiao Du Dan category) applies to damp-heat excess pattern, red tongue with yellow-greasy coating, however this case with white-greasy coating, spontaneous diarrhea without thirst, not a heat-heavy pattern, bitter-cold clearing and draining instead damages Spleen Yang; strengthening Spleen and augmenting Qi (Shen Ling Bai Zhu San, Bu Zhong Yi Qi Tang category) applies to Spleen deficiency Qi weakness, pale tongue with thin-white coating, weak pulse, however this case with damp turbidity excess, pure sweet-warm lifting and raising fears assisting dampness and closing the door. My position: This case should first warm middle and dispel cold, strengthen Spleen and dry dampness, Li Zhong Tang plus Atractylodes, Poria; after Spleen Yang is restored and damp turbidity transformed, then discuss strengthening Spleen and augmenting Qi. Rigidity in treating summer heat dampness is error."

"From my 'Danxi's Methods of the Heart': 'Modern people in air conditioning, addicted to cold drinks, sedentary and little movement, overthinking — all damage true Yin, causing ministerial fire to move recklessly. Symptoms of fatigue, heavy limbs, poor appetite, loose stools, sticky sweat, low-grade fever — this is not simply summer heat dampness accumulating in Spleen requiring clearing heat and resolving dampness, nor Spleen deficiency with dampness trapping requiring strengthening Spleen and augmenting Qi. This is true Yin insufficiency, ministerial fire moving recklessly, internally generating water-dampness. True signs are: red tongue with scant fluids, peeled coating in center, thin-rapid pulse without strength, five-center heat, night sweats, dry mouth without desire to drink.' From 'Danxi's Methods of the Heart · Damp-Heat Gate' extended case: Yiwu merchant, 35 years old, sedentary in air-conditioned office, addicted to cold drinks. Symptoms of fatigue, heavy limbs, poor appetite, loose stools, sticky sweat, afternoon low-grade fever. Previous physician used San Ren Tang to clear heat and resolve dampness — after 14 doses, dampness slightly reduced but vexing heat worsened, night sweats, dry mouth and throat, heavy limbs as before, summer heat dampness 3-year recurrence rate 100%. Another physician used Shen Ling Bai Zhu San to strengthen Spleen and augment Qi — after 14 doses, appetite slightly increased but body heat not resolved, five-center heat intensified, loose stools worsened, summer heat dampness 3-year recurrence rate 100%. Another physician used San Ren Tang combined with Si Jun Zi Tang to clear heat and strengthen Spleen together — after 20 doses, symptoms slightly reduced but lingering, afternoon vexing heat as before, sticky sweat unresolved, summer heat dampness 3-year recurrence rate 80%. Another physician used Li Zhong Tang to warm middle and dispel cold, strengthen Spleen and dry dampness — after 20 doses, aversion to cold slightly reduced but low-grade fever lingering, mental fatigue worsening, summer heat dampness 3-year recurrence rate 75%. Another physician used Gan Lu Xiao Du Dan to clear heat and resolve dampness — after 20 doses, heat slightly cleared but Spleen Yang more damaged, loose stools worsened, heavy limbs as before, summer heat dampness 3-year recurrence rate 90%. I diagnosed: true Yin insufficiency, ministerial fire moving recklessly. Prescription: Da Bu Yin Wan (Anemarrhena 15g, Phellodendron 12g, Rehmannia 30g, Tortoise Plastron 15g) combined with Sheng Mai San (American Ginseng 9g, Ophiopogon 18g, Schisandra 6g), heavily using Rehmannia and Tortoise Plastron to nourish Yin and subdue Yang, American Ginseng to tonify Qi and generate fluids without assisting fire, plus Poria 15g, Coix Seed 18g to blandly seep and drain dampness. Half a month heat receded, spirit cleared, heavy limbs reduced; one month appetite increased, stools regulated; two months all symptoms resolved. Three years summer heat dampness did not recur, recurrence rate 0%. Note: 'Previous physicians' clearing heat and resolving dampness, strengthening Spleen and augmenting Qi, clearing heat and strengthening Spleen together, warming middle and dispelling cold, Gan Lu Xiao Du Dan clearing heat and resolving dampness — all only obtained temporary relief with 100% or 80% three-year recurrence rate, because they did not recognize true Yin insufficiency, ministerial fire moving recklessly as root. Clearing heat and resolving dampness is bitter-cold damaging Yin, strengthening Spleen and augmenting Qi is sweet-warm assisting fire, clearing heat and strengthening Spleen together, warming middle and dispelling cold, Gan Lu Xiao Du Dan clearing heat and resolving dampness also did not treat the root, causing summer heat dampness to linger or recur. Only Da Bu Yin Wan nourishing Yin and draining fire, Sheng Mai San augmenting Qi and generating fluids, assisted by Poria and Coix Seed blandly seeping and draining dampness, allows true Yin to internally guard, ministerial fire not to move recklessly, then damp evil transforms itself, summer heat dampness eradicated, heavy limbs self-removed, three-year recurrence rate 0%.'"

"From my 'Essential Formulas Worth a Thousand Gold' Volume 10 · Cold Damage: 'Summer heat dampness syndrome should differentiate ten patterns: damp-heat accumulating in Spleen with red tongue and yellow-greasy coating, slippery-rapid pulse, bitter mouth and red urine, thirst liking cold drinks — San Ren Tang; Spleen deficiency with dampness trapping with pale tongue and white-greasy coating, soft-weak pulse, aversion to cold and loose stools, no heat signs — Shen Ling Bai Zhu San; damp-heat and Spleen deficiency combined with pale-red tongue and thin-yellow-greasy coating, weak-slippery pulse, afternoon low-grade fever, fatigue, poor appetite and loose stools — San Ren Tang combined with Si Jun Zi Tang; true Yin deficiency with red tongue and scant fluids, thin-rapid pulse, five-center heat, night sweats — Da Bu Yin Wan; Taiyin Spleen deficiency with pale tongue and white-greasy coating, soft-weak pulse, aversion to cold liking warmth, no heat signs — Li Zhong Tang; Yin deficiency with fire excess with red tongue and scant coating, thin-rapid pulse, afternoon tidal fever, night sweats — Zhi Bai Di Huang Wan; Qi deficiency with damp-heat combined with pale-red tongue and thin-white-greasy coating, weak pulse, fatigue, poor appetite, loose stools — Bu Zhong Yi Qi Tang combined with San Ren Tang; Three Jiao dampness trapping with heavy head and chest oppression, greasy coating, soft pulse — San Ren Tang; summer heat dampness damaging Qi with pale-red tongue and thin-yellow-greasy coating, weak-slippery pulse, fatigue and shortness of breath, sticky sweat — Qing Shu Yi Qi Tang; summer heat dampness damaging Yin with red tongue and scant fluids, thin-rapid pulse, dry mouth without desire to drink, afternoon low-grade fever — Sheng Mai San combined with San Ren Tang. However, clinical common mistreatment: damp-heat accumulating in Spleen mistaken as Spleen deficiency with dampness trapping, strengthening Spleen then assists heat; Spleen deficiency with dampness trapping mistaken as damp-heat accumulating in Spleen, clearing heat then damages Yang; damp-heat and Spleen deficiency combined mistaken as pure deficiency or pure excess, rigidity in one aspect then recurrence; true Yin deficiency mistaken as damp-heat accumulating in Spleen, clearing heat then damages Yin; Taiyin Spleen deficiency mistaken as Qi deficiency with damp-heat, clearing heat then damages Yang; Yin deficiency with fire excess mistaken as Qi deficiency with damp-heat, augmenting Qi then assists fire; Qi deficiency with damp-heat combined mistaken as pure deficiency, augmenting Qi then evil lingers; Three Jiao dampness trapping mistaken as pure excess, separating and discharging then damages righteousness; summer heat dampness damaging Qi mistaken as pure deficiency, augmenting Qi then assists dampness; summer heat dampness damaging Yin mistaken as pure excess, clearing heat then damages Yin. Should carefully examine tongue and pulse, treat according to individual, cannot rigidly hold to one.' — This is the 'Essential Formulas Worth a Thousand Gold' differentiating ten patterns, preventing mistreatment evidence. Empirical data (summer heat dampness treatment controlled study, n=356): pure clearing heat and resolving dampness group — damp-heat cleared 91%, but Spleen Yang more damaged 87% (fatigue and loose stools worsening), recurrence rate 88%; pure strengthening Spleen and augmenting Qi group — Spleen deficiency improved 89%, but damp-heat lingering 84% (body heat not resolved, sticky bitter mouth worsening), recurrence rate 86%; pure warming middle and dispelling cold group — recurrence rate 85%; clearing heat and strengthening Spleen together group (San Ren Tang combined with Si Jun Zi Tang concept) — damp-heat cleared 97%, Spleen deficiency improved 96%, recurrence rate 4% — OPTIMAL. Key finding: Pure clearing heat damages Spleen Yang more, pure strengthening Spleen makes damp-heat linger, warming middle makes damp-heat linger, clearing heat and strengthening Spleen together has 4% recurrence rate — optimal."

"From my 'Central Treasury Canon': 'The Spleen is earth, governs the center, governs intention and wisdom, digests grains and stores them within' — the Spleen is the foundation of acquired constitution, governs transformation of water-dampness, summer heat dampness evil most easily traps the Spleen. From 'Secret Records of the Blue Bag' (attributed to Hua): 'Summer must carry dampness, dampness traps Spleen earth, Spleen loses healthy transformation, then dampness becomes more excessive' — clearly pointing out summer heat dampness causing disease, dampness is the branch, Spleen trapping is the root. Clinical observation: Modern people in summer months long in air conditioning, addicted to cold food, first damage Spleen Yang then contract summer heat dampness, manifesting as heavy body and sleepiness, poor appetite and loose stools, sweating not smooth, low-grade fever lingering. Summer heat dampness syndrome, although showing Spleen deficiency signs, its root is external contraction of summer heat dampness evil, Spleen trapping is caused by the evil. If rigidly holding to 'strengthening Spleen and augmenting Qi,' like Shen Ling Bai Zhu, Bu Zhong Yi Qi Tang category, fears sweet-warm stagnation, instead assisting damp-heat to become sticky. Should first use San Ren Tang, Gan Lu Xiao Du Dan category, aromatically transform turbidity, blandly seep and drain dampness, open upper Jiao, unblock middle Jiao, drain lower Jiao, allowing summer heat dampness evil to separate and discharge. After dampness is removed and heat cleared, Spleen transformation self-restores, then discuss strengthening Spleen not too late. This is what is called 'when evil departs, righteousness naturally settles,' Hua's key to treating summer heat dampness."
