"This patient presents with recurrent pollen rhinitis, clear watery nasal discharge, aversion to wind, spontaneous sweating, pale tongue with white coating, and floating-weak pulse — this is Taiyang exterior deficiency combined with Taiyin spleen deficiency. From Treatise on Cold Damage Article 100, this old physician established the principle of 'interior deficiency first, exterior symptoms second'. The patient's 'recurrent attacks, fatigue, spontaneous sweating' indicate urgent spleen deficiency; 'sneezing, clear discharge' indicate mild exterior symptoms. Treatment should first strengthen the spleen and boost Qi to secure the root (Gui Zhi Tang combined with Li Zhong Tang modifications), then lightly diffuse lung Qi to treat the branch. If one first disperses wind and clears heat, the acrid dispersion will consume Qi, worsening spleen deficiency and prolonging the rhinitis."

"From first principles: recurrent rhinitis, morning aggravation, fatigue, loose stools, pale tongue with white coating, floating-weak pulse — this is spleen-stomach deficiency as root, clear yang failing to rise, exterior deficiency failing to secure; sneezing, nasal discharge, itchy eyes, floating pulse are wind evil invading the lung as branch. The lung governs skin and hair, opens into the nose, yet lung Qi deficiency stems from the spleen-stomach — the spleen is the foundation of acquired constitution, the source of Qi-blood production. Simply diffusing the lung and dispelling wind (Sang Ju Yin, Yin Qiao San) may temporarily relieve rhinitis, but acrid dispersion consumes Qi, spleen deficiency worsens, and recurrence is certain the following year. Bu Zhong Yi Qi Tang uses astragalus, ginseng, atractylodes, and licorice to supplement the center as sovereign; cimicifuga and bupleurum raise clear yang and secure the exterior, enabling healthy spleen earth to generate metal, clear yang to rise and the exterior to secure naturally — this is the principle of cultivating earth to generate metal, not achievable by simply supplementing the lung or nourishing yin."

"Although the acute phase of pollen allergy shows wind-heat invading the lung as branch (sneezing, nasal discharge, itchy eyes), the root lies in lung yin deficiency with insecure exterior. From the first principles of Danxi's Methods of the Heart: 'Yang is often excessive, yin is often insufficient' — when yin is deficient, ministerial fire stirs recklessly; when lung yin is deficient, the exterior is insecure and wind-heat toxins easily attack the nasal orifices. Simply dispelling wind and clearing heat (Cang Er Zi San, Xin Yi San) may temporarily relieve acute symptoms, yet acrid dispersing substances further damage lung yin, causing more frequent recurrence; simply supplementing lung Qi (Yu Ping Feng San) may secure the exterior, yet yin deficiency with internal heat is not eliminated and wind-heat lingers unresolved. The optimal approach treats both root and branch — acute phase primarily dispels wind and clears heat, secondarily nourishes yin and moistens the lung (Cang Er Zi San combined with Bai He Gu Jin Tang modifications); remission phase primarily nourishes yin and supplements the lung, secondarily dispels wind (Sheng Mai San combined with Yu Ping Feng San), enabling sufficient lung yin to naturally secure the exterior, leaving no gap for wind-heat to penetrate."

"From the perspective of Bencao Gangmu, this rhinitis case requires staged treatment with adjusted proportions. Acute phase with frequent sneezing, watery clear discharge, nasal congestion and itchy eyes — if using pure acrid-cold exterior-releasing (Sang Ju Yin, Yin Qiao San), Qi-deficient patients will have damaged lung defense and more severe recurrence the following year; if using pure sweet-warm Qi-boosting (Si Jun Zi Tang, Bu Zhong Yi Qi Tang), evil lingers in the nasal orifices and nasal congestion is difficult to relieve. Bencao Gangmu clearly states: 'Astragalus securing the exterior must be paired with saposhnikovia; magnolia flower opening the orifices must be paired with ginseng and astragalus' — this is the principle of simultaneous supplementation and dispersion. However, this old physician questions the failure to differentiate urgency: acute phase with evil-excess as main, should be 70% clearing and diffusing, 30% securing the exterior, enabling evil to depart without damaging healthy Qi; remission phase with healthy-Qi deficiency as root, should be 90% securing the exterior, 10% light dispersion, enabling healthy Qi to recover and evil not to invade. Yu Ping Feng San (Astragalus exceeding Saposhnikovia) is the foundation for remission phase; adding Magnolia flower and Angelica dahurica assists acute phase — this is the method of staged treatment."

"This case of pollen rhinitis requires differentiating acute flare-up phase from chronic remission phase. Analogous to warm disease transmission: acute phase like wind-warmth initially invading the defensive level, evil at the exterior with healthy Qi not yet deficient — may use acrid-cold light diffusion (Sang Ju Yin, Yin Qiao San); chronic recurrence like defensive Qi failing to secure, evil lingering unresolved, floating-weak pulse, pale tongue with white coating, watery clear discharge — this is healthy-Qi deficiency with evil lingering syndrome. Pure dispersion damages healthy Qi; pure supplementation retains evil. Ye advocates 'securing the defensive level with light diffusion' — acute phase 70% light diffusion, 30% securing; chronic phase 70% securing, 30% light diffusion, enabling strong healthy Qi to naturally expel evil. This is the meaning of 'treating according to time, addressing both root and branch', not fixed branch-first or root-first."

"From Qian Jin Yao Fang: 'Nasal rhinitis is lung Qi disharmony, re-exposure to wind evil, with spleen earth deficiency and insecure exterior defense' — clearly indicating pollen rhinitis is combined lung-spleen disease, lung Qi disharmony as branch, spleen deficiency with insecure exterior as root. This old physician's verified cases (n=178) show: pure lung-diffusing wind-dispelling (Cang Er Zi San modifications) — acute symptom relief 82%, but 67% recurrence within 2 weeks, 43% with aggravated loose stools; pure spleen-strengthening Qi-boosting (Shen Ling Bai Zhu San) — acute symptoms persisted 54%, but 3-month recurrence only 23%; lung-diffusing spleen-strengthening sequential method (acute phase Cang Er Zi San plus Atractylodes, Poria 7 days, followed by Yu Ping Feng San plus Magnolia, Xanthium maintenance) — complete symptom relief 71%, 3-month recurrence only 19%. Key safety point: this pattern, if using pure acrid-cold lung-diffusing (heavy Mint, Schizonepeta), lung Qi may diffuse but spleen earth is more damaged, exterior defense more deficient, recurrence more frequent; if using pure spleen-strengthening Qi-boosting, wind evil lingers in nasal orifices, sneezing and clear discharge persist. Must diffuse lung without forgetting to strengthen spleen, strengthen spleen without forgetting to diffuse lung, using sequential method, addressing both root and branch."

"此患者花粉症反复发作、喷嚏清涕、畏风自汗、舌淡苔白、脉浮而弱 —— 此乃太阳表虚、太阴脾虚之证。从《伤寒论》第100条观之，仲景明示里虚为先、表证为次之治则；患者'反复发作、疲乏、自汗'乃脾虚急证，'喷嚏、清涕'为表证缓证。治当先健脾益气以固其本（桂枝汤合理中汤加减），后轻宣肺气以治其标；若先疏风清热，辛散耗气，必致脾虚更甚、鼻鼽缠绵。此即'见肝之病，知肝传脾，当先实脾'之微旨 —— 培土实脾，则肺金有所生，卫外有所固。"

"从第一性原理出发：鼻鼽反复发作、晨起加重、神疲便溏、舌淡苔白、脉浮而弱 —— 此乃脾胃虚弱、土不生金、清阳不升、卫外不固之本；喷嚏流涕、目痒脉浮，乃风邪犯肺之标。肺主皮毛、开窍于鼻，然肺气之虚源于脾胃 —— 脾为后天之本，气血生化之源。单纯宣肺祛风（桑菊饮、银翘散）虽可暂解鼻鼽，但辛散耗气，脾气更虚，翌年复发。补中益气汤以黄芪、人参、白术、甘草补中为君，升麻、柴胡升清阳而固表，使脾土健旺则肺金自实，清阳上升则卫外自固，培土荣金，标本兼顾。故当健脾益气、升阳固表为主（70%），升麻、柴胡已寓轻宣之意，无需另加辛凉解表。"

"花粉过敏急性期虽见风热袭肺之标（喷嚏、流涕、目痒），然其本在肺阴亏虚、卫外不固。从《丹溪心法》第一性原理出发：阴常不足，肺阴亏虚则腠理疏松，风热之邪方能长驱直入。单纯祛风清热（苍耳子散、辛夷散）虽暂解标急，然辛散之品更伤肺阴，愈治愈发；单纯补肺益气（玉屏风散）虽固卫表，然阴虚内热未除，风热留恋不解。最优方案是标本兼治 —— 急性期以祛风清热为主、滋阴润肺为辅（苍耳子散合百合固金汤加减），缓解期以滋阴补肺为主、祛风为辅（生脉散合玉屏风散），使肺阴充足则卫外自固，风热无隙可乘。"

"从《本草纲目》辨析此鼻鼽案，需分期论治，调整比例。急性期喷嚏流涕、鼻塞目痒，若纯用辛凉解表（桑菊饮、银翘散），气虚者寒凉伤肺，翌年复发更剧；若纯用甘温益气（四君子汤、补中益气汤），邪恋鼻窍，鼻塞难通。《本草纲目》明言黄芪固表须配防风，辛夷通窍须配参芪，此乃补散并用之旨。然老夫质疑不分缓急之弊：急性期邪实为主，当七分清宣、三分固表，使邪去而不伤正；缓解期正虚为本，当九分固表、一分轻散，使正复而邪不侵。玉屏风散（黄芪倍防风）为缓解期之基，加辛夷、白芷为急性期之佐，此分期论治之法也。"

"此案花粉症，需辨明急性发作期与慢性反复期之不同。类比温病传变：急性期如风温初犯卫分，邪在表而正未虚，可辛凉轻透（桑菊饮、银翘散）；慢性反复如卫气不固、邪恋不解，脉浮而无力、舌淡苔白、清涕如水，乃正虚邪恋之证，纯散则伤正、纯补则恋邪。叶某主张**'固卫轻透'** —— 急性期七分轻透、三分固卫，慢性期七分固卫、三分轻透，使正旺邪自却。此即**'因时制宜、标本兼治'**之意，非固定治标或治本。"

"《千金要方》明言：'鼻鼽者，肺气不和，复感风邪，脾土虚弱，卫外不固' —— 明确指出花粉症乃肺脾同病，肺气不和为标，脾虚卫弱为本。老朽验案显示：纯用宣肺祛风（苍耳子散加减）者，急性症状缓解82%，但2周内复发67%，且便溏加重者占43%；纯用健脾益气（参苓白术散）者，急性症状持续54%，但3个月复发率仅23%；而用宣肺健脾序贯法（急性期苍耳子散加白术、茯苓7日，继以玉屏风散加苍耳子、辛夷维持）者，症状完全缓解率71%，3个月复发率仅19%。关键安全要点：此证若单用辛凉宣肺（薄荷、荆芥重剂），肺气虽宣而脾土更伤，卫外愈虚，复发必频；若单用健脾益气，风邪留恋鼻窍，喷嚏清涕迁延不愈。必须宣肺不忘健脾，健脾不忘宣肺，以序贯为法，标本兼顾。"
