(Attached to Alternating Chills and Fever)
Summer injury by Shu (Summer Heat) [Shu, 暑: Summer-Heat pathogen] leads to Nuojue (Malaria) [Nuojue, 疟: Malaria] in autumn. It is also said that Nuojue disease must originate from Feng (Wind) [Feng, 风: Wind pathogen]. The statements in Nei Jing (Inner Canon of the Yellow Emperor) [Nei Jing, 内经: Inner Canon of the Yellow Emperor] should be carefully considered. During the peak of summer heat, the Couli (pores and interstitial spaces) [Couli, 腠理: Pores and interstitial spaces] are open, sweat is produced, and exposure to wind occurs, or after bathing, one is exposed to cold and dampness.
Wei Qi (Defensive Qi) [Wei Qi, 卫气: Defensive Qi] fails to guard, and Xie Qi (Evil Qi/Pathogenic factors) [Xie Qi, 邪气: Pathogenic factors] invades internally, lodging in Moyuan (Membrane Source) [Moyuan, 膜原: Membrane Source], manifesting severely at the corresponding time. Contracting Wind on a hot day provides the root cause. However, children often suffer from food retention (Shi Tuan) [Shi Tuan, 食抟: Food retention/stagnation]; with weak Spleen and declining Stomach function, milk and food stagnate, allowing various pathogens to attach. These conflict with Zheng Qi (Upright Qi) [Zheng Qi, 正气: Upright/Healthy Qi], obstructing Yin and Yang, causing the two energies to intertwine. When Yin is excessive and Yang deficient, chills and trembling occur first; when Yang is excessive and Yin deficient, intense heat occurs first. When Xie Qi combines with Wei Qi, attacks are sudden ("huo huo"). When Xie Qi penetrates deeply into the interior, the disease manifests every other day.
Nuojue always involves Tan (Phlegm) [Tan, 痰: Phlegm] stagnating in the chest and diaphragm; it always involves Shi (Dampness) [Shi, 湿: Dampness], causing soreness and pain in the hands and feet. Dan Nuo (Hot Malaria), Pin Nuo (Cold Malaria), Wen Nuo (Warm Malaria), Han Nuo (Chill Malaria), Gui Nuo (Ghost Malaria), and Zhang Nuo (Miasma Malaria) have different names and symptoms but can be roughly summarized. Cold rises in the fine hairs, yawning and listlessness occur, trembling and jaw-chattering happen, and headache feels like drilling. When fever sets in, internal and external heat scorches, thirst arises with desire to drink, body ache and tendon binding occur. Whether starting with cold invasion or heat scorching, Yin and Yang become unbalanced, alternating like social exchanges. Thus, alternating chills and fever occur rhythmically. Zhu Danxi stated this most accurately. For no sweat, induce sweating to disperse Xie Qi as the primary goal; for existing sweat, stop sweating to secure Zheng Qi quickly. The aim is to eliminate all Xie Qi and harmonize Yin and Yang. Regrettably, worldly physicians do not know how to prescribe, treating Xiao Chai Hu Tang (Minor Bupleurum Decoction) [Xiao Chai Hu Tang, 小柴胡汤: Minor Bupleurum Decoction] as a fixed method. They ignore the repeated warnings of former sages: taking Chai Hu (Bupleuri Radix) [Chai Hu, 柴胡: Bupleuri Radix] too early leads to lingering and difficult-to-resolve disease. Xie Qi should be dispersed from the exterior so Zheng Qi is not depleted internally. Only by harmonizing Yin and Yang can purgative methods be considered. One must not be negligent or superficial; careful deliberation is essential.
For chronic Nuojue that does not heal, Nuomu (Malaria Mother/Splenomegaly) [Nuomu, 疟母: Splenomegaly/Mass due to malaria] forms internally, palpable between the chest and hypochondrium. Treatment should focus on dissipation to prevent weakening of Zheng Qi.
Zeng said: Nei Jing's "Treatise on Malaria" states: "Summer injury by Shu leads to Nuojue in autumn." This refers to open Couli and sweat upon encountering wind, or water qi lodging in the skin after bathing, because Wei Qi fails to guard and Xie Qi resides together, initiating the disease. Symptoms include yawning, chills, pain in the waist and back, and severe joint pain. When cold generates, both interior and exterior become hot, accompanied by headache and thirst. This results from the struggle between Yin and Yang energies and the alternation of deficiency and excess. If Yin alone is excessive, Yang becomes deficient, causing initial chills and trembling, with pain in the waist, back, head, neck, and joints. If Yang alone is excessive, Yin becomes deficient, causing initial heat, anorexia during attacks, preference for vomiting, headache, lower back pain, and difficulty urinating. Yin excess and Yang deficiency lead to internal and external cold; Yin excess and Yin deficiency (likely meant Yang deficiency relative to Yin excess or vice versa in context of heat/cold patterns) lead to internal and external heat. This is caused by external contraction of the Six Excesses (Liu Yin) [Liu Yin, 六淫: Six Exogenous Pathogens] or internal injury from the Seven Emotions (Qi Qing) [Qi Qing, 七情: Seven Emotions], accumulating Tan and Yin (Fluids) [Yin, 饮: Fluid retention], where Bing Qi (Disease Qi) and Wei Qi reside together, causing daily attacks. Wei Qi travels through Yang during the day and Yin at night; it moves outward when meeting Yang and inward when meeting Yin. When Zang-Fu disease Qi penetrates deeply and cannot exit with Wei Qi, the disease manifests every other day. When Wei Qi arrives at the location of the disease Qi, the attack begins. In Yang, there is heat; in Yin, there is cold. When Yin and Yang decline separately, Wei Qi separates from Disease Qi, and the disease rests. When Yin and Yang contend, and Wei Qi gathers with Disease Qi, the disease recurs. This depends on the location of Wei Qi and its combination with the contracted Xie Qi.
Chills followed by heat indicates initial injury by Cold then Wind, named Han Nuo (Chill Malaria). Heat followed by chills indicates initial injury by Wind then Cold, named Wen Nuo (Warm Malaria). Heat without chills is named Dan Nuo (Hot Malaria). Heavy body, alternating chills and fever, joint pain, abdominal fullness, spontaneous sweating, and frequent vomiting is named Shi Nuo (Damp Malaria). Chills without heat is named Pin Nuo (Cold Malaria). Since diseases vary, treatment must follow Yin/Yang and Deficiency/Excess, using Sweating, Vomiting, Purging, and Warming methods, targeting symptoms to achieve balance. However, it is always due to Zheng Qi deficiency contracting Xie Qi, which remains and causes Excess conditions. Transmission from Exterior to Interior requires Sweating first, then Purging, unchanged since ancient times. Therefore, treating Nuojue must start with releasing the Exterior, using Bai Jie San (Hundred Dissolution Powder) [Bai Jie San, 百解散: Hundred Dissolution Powder] plus Ginger and Scallion, followed by Xiao Chai Hu Tang plus Guizhi (Cinnamon Twig) [Guizhi, 桂枝: Cinnamon Twig], Ginger, and Jujube to harmonize and release Exterior-Interior Xie Qi, naturally yielding results. If Exterior and Interior are Excess, use Dang Gui San (Angelica Powder) [Dang Gui San, 当归散: Angelica Powder], Wu He Tang (Five Harmonies Decoction) [Wu He Tang, 五和汤: Five Harmonies Decoction], or Wu Xi Wan (Black Rhinoceros Pill) [Wu Xi Wan, 乌犀丸: Black Rhinoceros Pill] to purge. Yun Qi San (Harmonizing Qi Powder) [Yun Qi San, 匀气散: Harmonizing Qi Powder] stops tonification. Later, use Huo Xiang Yin (Agastache Drink) [Huo Xiang Yin, 藿香饮: Agastache Drink] plus Cao Guo (Tsaoko Cardamom Fruit) [Cao Guo, 草果: Tsaoko Cardamom Fruit], Liang Jiang (Galangal) [Liang Jiang, 良姜: Galangal], Ginger, and Jujube to regulate Stomach Qi and remove Cold Xie Qi, leading to natural recovery. If Exterior is resolved but alternating chills and fever persist, use Er Xian Yin (Two Immortals Drink) [Er Xian Yin, 二仙饮: Two Immortals Drink] to intercept. Once chills and fever cease, use Ping Wei San (Peaceful Stomach Powder) [Ping Wei San, 平胃散: Peaceful Stomach Powder] mixed with salt water on an empty stomach to warm the Stomach and strengthen the Spleen, clearing external Xie Qi naturally. This is a clear theory. For cases with more chills than heat, lingering long-term, causing weak Spleen/Stomach, poor appetite, and altered complexion, treat with Er Jiang Wan (Two Gingers Pill) [Er Jiang Wan, 二姜丸: Two Gingers Pill] and Qing Pi Tang (Clear Spleen Decoction) [Qing Pi Tang, 清脾汤: Clear Spleen Decoction].
Lou Quanshan said: Treating pediatric Nuojue is mostly similar to adults, aiming for sweating as recovery. Suitable herbs include Guizhi, Chai Hu, Ren Shen (Ginseng Root) [Ren Shen, 人参: Ginseng Root], and Huang Qin (Scutellaria Root) [Huang Qin, 黄芩: Scutellaria Root]. For food or phlegm diseases, adjust according to circumstances. Children often get it from food accumulation, requiring digestive herbs first.
Ye Gui said: Nuojue is mostly triggered by Shu. Although formularies distinguish between Phlegm, Food, Cold, Heat, Miasma, and Pestilence, pediatric Nuojue always stems from Spleen/Stomach pathology. However, children have weak Qi and Spirit, often presenting initially with Jing Xian (Startle Epilepsy) [Jing Xian, 惊痫: Startle Epilepsy] or Jue Ni (Reversal Collapse) [Jue Ni, 厥逆: Reversal Collapse]. In summer and autumn, never mistake it for Jing Xian. Adult Nuojue must be differentiated by the Twelve Meridians, similar to cough syndromes. Vulgar pediatricians only use Xiao Chai Hu Tang minus Ren Shen, or herbs like Xiang Ru (Patrinia Herb) [Xiang Ru, 香薷: Patrinia Herb] and Ge Gen (Kudzu Root) [Ge Gen, 葛根: Kudzu Root], unaware that Chai Hu damages Liver Yin and Ge Gen depletes Stomach fluids, causing frequent complications. Children are purely Yang; Shu is Hot Qi, so symptoms are predominantly heat with irritability and thirst. If Xie enters via the Lung, Gui Zhi Bai Hu Tang (Cinnamon Twig and White Tiger Decoction) [Gui Zhi Bai Hu Tang, 桂枝白虎汤: Cinnamon Twig and White Tiger Decoction] cures it in two doses. If cold food fails to transform, showing Taiyin Spleen symptoms, initially support Zheng Qi or use acrid-warm herbs like Cao Guo, Sheng Jiang (Fresh Ginger) [Sheng Jiang, 生姜: Fresh Ginger], and Ban Xia (Pinellia Tuber) [Ban Xia, 半夏: Pinellia Tuber]. Formularies state Cao Guo treats Taiyin-exclusive Cold, and Zhi Mu (Anemarrhena Rhizome) [Zhi Mu, 知母: Anemarrhena Rhizome] treats Yangming-exclusive Heat. For chronic Nuojue with pallor, white lips, profuse sweating, and weakness, Si Shou Yin (Four Beasts Drink) [Si Shou Yin, 四兽饮: Four Beasts Drink] is necessary. For Yin deficiency with internal heat, use Bie Jia (Tartar Turtle Shell) [Bie Jia, 鳖甲: Tartar Turtle Shell], Shou Wu (Polygonum Multiflorum Root) [Shou Wu, 首乌: Polygonum Multiflorum Root], and Zhi Mu. Avoid if stool becomes loose. For chronic Nuojue with Ying/Blood Cold and Xie Heat, add Guizhi and Jiang. Refer to the left for Nuojue medications. For initial summer-damp-wind-heat Nuojue with epigastric stuffiness, use Jie Geng (Platycodon Root) [Jie Geng, 桔梗: Platycodon Root], Zhi Ke (Aurantii Fructus) [Zhi Ke, 枳壳: Aurantii Fructus], Xing Ren (Apricot Seed) [Xing Ren, 杏仁: Apricot Seed], Hou Po (Magnolia Bark) [Hou Po, 厚朴: Magnolia Bark] (best for wheezing), Gua Lou Pi (Trichosanthes Peel) [Gua Lou Pi, 栝蒌皮: Trichosanthes Peel], Shan Zhi (Gardenia Fruit) [Shan Zhi, 山栀: Gardenia Fruit], and Chi Dou (Fermented Soybean) [Chi Dou, 香豉: Fermented Soybean]. For headache, use acrid-cool light agents: Lian Qiao (Forsythia Fruit) [Lian Qiao, 连翘: Forsythia Fruit], Bo He (Mint) [Bo He, 薄荷: Mint], Chi Shao (Red Peony Root) [Chi Shao, 赤芍: Red Peony Root], Ling Yang Jiao (Antelope Horn) [Ling Yang Jiao, 羚羊角: Antelope Horn], Man Jing Zi (Vibrant Seed) [Man Jing Zi, 蔓荆子: Vibrant Seed], and Hua Shi (Talcum) [Hua Shi, 滑石: Talcum] (this formula clears upper jiao with bland leaching). For severe cases, use Shi Gao (Gypsum Fibrosum) [Shi Gao, 石膏: Gypsum Fibrosum]. For thirst, use Hua Fen (Trichosanthes Root) [Hua Fen, 花粉: Trichosanthes Root]. For vexatious thirst, use Zhu Ye Shi Gao Tang (Bamboo Leaf and Gypsum Decoction) [Zhu Ye Shi Gao Tang, 竹叶石膏汤: Bamboo Leaf and Gypsum Decoction]. For extreme heat, use Huang Qin, Huang Lian (Coptis Rhizome) [Huang Lian, 黄连: Coptis Rhizome], and Shan Zhi. Summer body pain due to dampness: avoid acrid-warm Qiang Huo (Notopterygium Root) [Qiang Huo, 羌活: Notopterygium Root] and Fang Feng (Saposhnikovia Root) [Fang Feng, 防风: Saposhnikovia Root]. Use Mu Fang Ji (Stephania Root) [Mu Fang Ji, 木防己: Stephania Root] and Can Sha (Silkworm Frass) [Can Sha, 蚕沙: Silkworm Frass]. Shu-Heat Xie injury starts in Qi level; if unresolved long-term, it enters Blood level, causing paradoxical thirst with little drinking, crimson lips/tongue. Use Qin Lian Gao (Honeysuckle and Coptis Paste) [Qin Lian Gao, 芩连膏: Honeysuckle and Coptis Paste]. If ineffective, use Blood-invigorating herbs, cooling while clearing Qi-level heat; one herb suffices. Mildly use Dan Pi (Moutan Cortex) [Dan Pi, 丹皮: Moutan Cortex] (avoid if sweating profusely), Qing Hao (Artemisia Annua Herba) [Qing Hao, 青蒿: Artemisiae Annuae Herba], Xi Jiao (Rhinoceros Horn) [Xi Jiao, 犀角: Rhinoceros Horn], Zhu Ye Xin (Bamboo Leaf Heart) [Zhu Ye Xin, 竹叶心: Bamboo Leaf Heart], Yuan Shen (Scrophularia Root) [Yuan Shen, 元参: Scrophularia Root], Xian Sheng Di (Fresh Rehmannia Root) [Xian Sheng Di, 鲜生地: Fresh Rehmannia Root], Xi Sheng Di (Fine Rehmannia Root) [Xi Sheng Di, 细生地: Fine Rehmannia Root], Mu Tong (Akebia Stem) [Mu Tong, 木通: Akebia Stem] (can also induce sweating), and Dan Zhu Ye (Lophatherum Herb) [Dan Zhu Ye, 淡竹叶: Lophatherum Herb]. If heat persists with stagnation, select Xie Xin Tang (Drain the Epigastrium Decoction) [Xie Xin Tang, 泻心汤: Drain the Epigastrium Decoction]. In summer, prolonged heat entering Blood often causes Blood Stasis: delirium, coma, madness. If urine is clear and abundant, stool will likely be black. Tao Ren Cheng Qi Tang (Peach Kernel and Cathartic Decoction) [Tao Ren Cheng Qi Tang, 桃仁承气汤: Peach Kernel and Cathartic Decoction] is essential. For chronic pediatric Nuojue with facial swelling, abdominal distension, diarrhea, anorexia, scrotal edema, or foot swelling, use Dongyuan's method to tonify Qi and raise Yang. If Spleen Yang is exhausted and previous formulas fail, use Li Zhong Tang (Regulate the Middle Decoction) [Li Zhong Tang, 理中汤: Regulate the Middle Decoction] or Qian's Yi Huang San (Strengthen Earth Powder) [Yi Huang San, 益黄散: Strengthen Earth Powder]. After 2-3 days of efficacy, administer Wu Ling San (Five Ingredient Powder with Poria) [Wu Ling San, 五苓散: Five Ingredient Powder with Poria]. After 1-2 days, use Yi Gong San (Single Skill Powder) [Yi Gong San, 异功散: Single Skill Powder] or Shen Ling Bai Zhu San (Ginseng, Poria, and Atractylodes Macrocephala Powder) [Shen Ling Bai Zhu San, 参苓白术散: Ginseng, Poria, and Atractylodes Macrocephala Powder] until fully recovered. Xu Zhongke annotated Jin Gui, stating: For infants not yet eating grain, chronic Nuojue unrelenting, use strong rock sugar soup; I tested this and it works. Nuojue often uses Wu Mei (Mume Fruit) [Wu Mei, 乌梅: Mume Fruit] to sour-drain Wood and calm Earth. Using Chang Shan (Polygala Root) [Chang Shan, 常山: Polygala Root] and Cao Guo are drugs to rob Taiyin; Chang Shan is extremely mobile, preventing the two evils from combining. Using Ren Shen and Sheng Jiang is called Lu Jiang Yin (Dew Ginger Drink) [Lu Jiang Yin, 露姜饮: Dew Ginger Drink], one to secure Yuan Qi, one to disperse Xie Qi, aiming to clarify spirit and remove foul qi. Ultimately, chronic Nuojue depletes Qi; strengthening Gallbladder Qi can stop Nuojue; there may not truly be a Nuojue ghost. Furthermore, long-standing Nuojue Xie penetrates deep into Blood level or forms Nuomu; Bie Jia Jian Wan (Turtle Shell Decoction Pill) [Bie Jia Jian Wan, 鳖甲煎丸: Turtle Shell Decoction Pill] is used. If decoctions are set, blood-invigorating and collateral-unblocking methods suffice.
