Shao's Commentary: During the summer months, heat qi and damp turbidity evaporate and mix to form foul miasmic toxins, known as "Sha Hui" (sand-miasma). When the human body is invaded by this pathogen, it first enters through the mouth and nose. If one is subsequently exposed to summerheat, the pathogen remains latent in the *Mo Yuan* (Membrane Source, a location between the exterior and interior), resulting in symptoms such as headache and alternating chills and fever. The pathogen obstructs the mechanism of Qi movement, preventing the Yang from being disseminated and transported; thus, manifestations such as cold limbs, deep/fine pulse, vomiting, diarrhea, abdominal pain, and oppression occur. Treatment should employ acrid-aromatic herbs to expel filth and light-bland herbs to clear summerheat, separating the summerheat from the filth so that the pathogen dissipates and the disease resolves. If there is food stagnation in the Middle Jiao (Spleen and Stomach), add herbs that promote digestion and resolve stagnation.
If one is touched by summerheat-filth, causing abdominal pain, and mistakenly drinks Ginger-Sugar Decoction, leading to Cholera (*Huo Luan*), with symptoms of intractable vomiting and diarrhea, all six pulses becoming deep/fine, and severe intestinal colic resembling death, this is due to internal closure. External treatments include bloodletting for Sha (*Fang Sha*), lifting Sha (*Ti Sha*), and scraping (*Gua Sha*). Internally, urgently administer Chuan Yu Jin (Curcuma Aromatica Rhizome), Shi Chang Pu (Acori Tatarinowii Rhizoma), Xi Huang (Calculus Bovis, administered separately), Chuan Lian (Coptidis Rhizoma), Cao Dou Kou (Cardamomi Fructus), Huo Xiang (Agastaches Herba), Mu Xiang (Aucklandiae Radix), Hua Shi (Talcum), and Tong Cao (Tetrapanacis Medulla) to open the closure and expel filth.
Shao's Commentary: Ginger's warmth conflicts with summerheat; sugar's cloying nature conflicts with Sha-miasma. Mistakenly drinking Ginger-Sugar Decoction causes pathogenic factors to stagnate in the Middle Jiao, creating rejection between the upper and lower, leading to chaotic Qi movement, inability to vomit or defecate, severe abdominal cramping, and non-rising deep pulses. This is the "Jiao Chang Sha" (Intestinal Colic Sha) syndrome caused by internal pathogenic closure. Urgently use acupuncture, lifting, and scraping external therapies to open and drain the Qi in the blood collaterals and physiological apertures. Internally, administer acrid-aromatic dispersing agents to open closure, expel filth, disperse pathogens, and unblock Qi. If the condition is severe and does not respond, San Wu Bei Ji Wan may be taken using the method of warm opening.
Summerheat Accompanied by Food Stagnation: Patients presenting with headache, aversion to cold on the back, fever with spontaneous sweating, left pulse deficient and right pulse slippery, aversion to eating, and chest fullness are suffering from Summerheat injury combined with Food Injury. Suitable herbs include Huo Xiang (Agastaches Herba), Hou Po (Magnoliae Officinalis Cortex), Qing Pi (Citri Reticulatae Pericarpium Viride), Xiang Ru (Moslae Herba), Shen Qu (Massa Medicata Fermentata), Zha Rou (Crataegi Fructus), Zhi Shi (Aurantii Fructus Immaturus), Mai Ya (Hordei Fructus Germinatus), Zi Su (Perillae Folium), and Hua Shi (Talcum), to disperse and clear.
Shao's Commentary: This is the standard method for clearing summerheat and eliminating food stagnation.
Pathogen Knotting in the Lower Jiao: Summerheat and Dampness combine as pathogens, knotting in the Qi level of the Lower Jiao, resulting in hardness and fullness of the lower abdomen, constipation, and a white tongue coating with slight yellow. This indicates pathogenic knotting in the Qi level of the Lower Jiao. Do not treat it as constipation due to fluid depletion in Cold Damage (*Shang Han*). Suitable herbs include Zhu Ling (Polypori Sclerotium), Chi Ling (Poria Cum Radio), Hua Shi (Talcum), Tong Cao (Tetrapanacis Medulla), Dan Zhu Ye (Lophatheri Herba), Wan Can Sha (Bombyx Batryticatus), and Zhao Jia Zi (Gleditsiae Sinensis Spina), to resolve the knotting in the Qi level of the Lower Jiao, allowing urination and defecation to flow freely.
Shao's Commentary: In combined Summerheat-Dampness pathogens, Summerheat is mild while Dampness is heavy, pouring into the Lower Jiao and knotting in the Qi level, causing lower abdominal hardness and fullness. Since Qi is not disseminated and transported, defecation does not occur. However, urination may also not be smooth. A white tongue coating with slight yellow indicates more Dampness than Summerheat. Dampness obstructing Qi mechanism leads to difficulty in both urination and defecation, which is vastly different from constipation due to fluid depletion in Cold Damage. Treatment employs the method of leaching out Dampness and opening Qi. Once the knotted pathogen in the Lower Jiao is opened and transformed, urination and defecation will proceed, and the pathogen will naturally transform.
Active Summerheat (*Dong Shu*): Laborers and farmers who work under the midday sun contract this disease, known as *Zhong Yue* (Heat Stroke/Summerheat Strike). Symptoms include headache, restlessness, aversion to heat, skin feeling very hot to the touch, extreme thirst with desire to drink, profuse sweating, and Qi deficiency so severe that even movement is difficult. This is Heavenly Heat injuring Yuan Qi externally. Treatment should tonify Qi and clear Summerheat. According to Zhang Zhongjing: "Taiyang Summerheat Heat" refers to this condition. Symptoms include sweating, aversion to cold, fever, and thirst. The main formula is Bai Hu Tang (White Tiger Decoction) plus Ren Shen (Ginseng Radix et Rhizoma). Because Yuan Qi is injured by heat pathogens, causing high fever, extreme thirst, and incessant sweating, Ren Shen is used to tonify Qi, and Shi Gao (Gypsum Fibrosum) to clear Summerheat. This is an exquisite and appropriate method. Why did later generations replace it with Li Dongyuan's Qing Shu Yi Qi Tang? I fear that when Summerheat pathogens are vigorous, the ascending properties of Sheng Ma and Ge Gen, and the binding nature of Bai Zhu, might assist the pathogen and worsen the disease. Only Sheng Mai San (Generate the Pulse Powder) plus Shi Gao can serve as a substitute. However, those with strong constitution and Qi need only take Liu Yi San (Six-to-One Powder) to resolve the heat. Li Dongyuan's decoction is intended for chronic cases where Summerheat-Dampness injures Qi and affects the Spleen and Stomach. Using it to treat acute Summerheat strike would be erroneous.
Quiet Summerheat (*Jing Shu*): One staying quietly in tall buildings may not feel external heat, but occasional exposure to Summerheat during social interactions can still cause Summerheat strike. Examples include greeting guests, viewing lotuses, or airing books—accidental contact with Summerheat pathogens. Furthermore, in small, low rooms where external heat presses in, even staying quietly indoors allows inhalation of Summerheat pathogens. All these should be treated as typical Summerheat.
Yin Summerheat (*Yin Shu*): Medical texts prescribe Da Shun San (Great Harmony Powder) for Yin Summerheat, but this is not actually Summerheat; it is Yin-Cold contracted during the Summer months. However, the herbs in Da Shun San are roasted and contain heavy doses of Gan Cao (Licorice Root), and although Xing Ren (Armeniacae Semen) directs Qi downward, they are primarily sweet-warm and middle-stabilizing, lacking the ability to disperse Cold and break knots. Thus, it is unsuitable even for internal Cold damage and external Yin-Cold contraction. For healthy individuals avoiding heat in mountain pavilions or water towers, excessive indulgence in coolness leading to wind-cold contraction, resulting in chills, fever, no sweat, headache, aversion to cold, and fever, is due to whole-body Yang Qi being suppressed by Cold. This should be treated according to Cold Damage principles, using gentle warming and dispersing methods. Herbs such as Zi Su (Perillae Folium), Bo He (Menthae Haplocalycis Herba), Huo Xiang (Agastaches Herba), and Hou Po (Magnoliae Officinalis Cortex) are suitable. If one indulges in melons and fruits, causing internal Cold damage leading to abdominal pain, vomiting, diarrhea, deep-slow pulse, and cold extremities, this is Taiyin Cold Damage. It is treated with Li Zhong Tang (Regulate the Middle Decoction) plus Huo Xiang (Agastaches Herba) and Hou Po (Magnoliae Officinalis Cortex).
Yang Summerheat (*Yang Shu*): This is the Active Summerheat mentioned above. (The above treatment methods are compiled from Ye Tianshi's medical cases and *Shu Zheng Quan Shu*).
Summerheat Wind (*Shu Feng*): Patients in the Summer months suddenly experiencing hand and foot spasms suffer from Summerheat Wind. Use Xiang Ru Yin (Mosla Decoction) plus Qiang Huo (Notopterygii Rhizoma et Radix) and Fang Feng (Saposhnikoviae Radix). For vomiting and nausea, add Huo Xiang (Agastaches Herba) and Chen Pi (Citri Reticulatae Pericarpium). For difficult urination, add Zhu Ling (Polypori Sclerotium), Fu Ling (Poria), Ze Xie (Alismatis Rhizoma), and Hua Shi (Talcum). For phlegm, add Ban Xia (Pinelliae Rhizoma). For thirst, replace existing herbs with Gua Lou (Trichosanthis Fructus). For persistent diarrhea, add Cang Zhu (Atractylodis Rhizoma). For muscle twitching/cramps, add Mu Gua (Chaenomelis Fructus).
In severe cases, hands and feet spasm and convulse, with opisthotonos, resembling Evil Invasion. Some patients initially had heat illness, and after taking exterior-releasing medicines, gradually developed wind patterns, manifesting as delirious speech, wild shouting and running, and superhuman strength; this is also due to Summerheat Qi. Treat with cold-cooling purgative methods, combined with dispersing and resolving phlegm.
Summerheat Consumption Disease (*Shu Zhai*): In peak Summer months, Fire can melt Metal (Lung). If one does not abstain from spicy foods and alcohol, Spleen Fire becomes violent, causing labor-heat and restlessness. Fire agitates the Heart and Spleen, leading to coughing, wheezing, sudden hematemesis (vomiting blood), epistaxis (nosebleed), unclear head and eyes, and restless oppression in the diaphragm. Even children and the elderly occasionally suffer from this. Ignorant practitioners mistake it for Lao Zhai (Consumption/Tuberculosis), not realizing that this is fire carrying blood upward, which is not comparable to deficiency-consumption caused by True Yin depletion. Treatment should clear Summerheat and cool blood, using herbs such as He Ye Zhi (Nelumbinis Folium Juice), Xian Di Huang (Rehmanniae Radix Recens), Yuan Shen (Scrophulariae Radix), Zhi Mu (Anemarrhenae Rhizoma), Shi Gao (Gypsum Fibrosum), Yu Jin (Curcumae Radix), Lian Qiao (Forsythiae Fructus), Xing Ren (Armeniacae Semen), and Xiang Bei Mu (Fritillariae Thunbergii Bulbus).
Summerheat Ulcer (*Shu Yang*): Generally, carbuncles and toxic sores have periodic fever, with evening fever subsiding by morning. In summer, if someone suffers from red swelling of the head, face, neck, or legs and feet extending several inches, making walking impossible, people often suspect toxic sores. However, if accompanied by headache and internal restlessness, with ceaseless day-and-night fever, it differs from toxic sores. Treatment should clear Summerheat and detoxify, using herbs like Chuan Lian (Coptidis Rhizoma) and Shi Gao (Gypsum Fibrosum). Once the Summerheat toxin is resolved, the swelling subsides naturally, without pus or blood.
Summerheat Rash (*Shu Chuang*): During peak Summer, blisters appear all over the body, like bowls or cups, like plums or peaches, crystal clear, thin, and brittle, containing foul-smelling fluid. This is Damp-Heat water flooding the muscle surface. Use Huang Lian Xiang Ru Jie Du Tang (Coptis and Mosla Detoxifying Decoction). If there is oral ulceration with foul odor, Liang Ge San (Cool the Diaphragm Powder) is effective. Externally, apply fresh Lotus petals to the rash; it heals within a week. (The above four items are from *Shu Zheng Quan Shu*).
