[Symptoms] If the symptoms are consistent among the general population, it belongs to this category.
[Treatment Principles] There are three treatment methods: tonification (Bu), dispersion (San), and descending (Jiang).
Prescription Composition: Rhizoma et Radix Notoginseng (Dahuang), Cortex Eucommiae (Huangqin), Rhizoma Coptidis (Huanglian), Radix Ginseng (Renshen), Flos Platycodonis (Jiegeng), Rhizoma Atractylodis Macrocephalae (Cangzhu), Ramulus Saposhnikoviae (Fangfeng), Talcum (Huashifen), Human Excrement Middle Layer (Renzhonghuang), Rhizoma Cyperi (Xiangfuzi).
The above herbs are processed with Massa Medicata Fermentata (Shenqu) into pills. They should be taken with appropriate decoctions based on individual conditions. For Qi deficiency, use Sijunzi Tang (Four Gentlemen Decoction); for Blood deficiency, use Siwu Tang (Four Substances Decoction); for Phlegm, use Erchen Tang (Two Aged Herbs Decoction); for severe heat, take the pills down with urine from a healthy child (Tongbian).
In spring and summer, do not administer Ephedrae Herba (Mahuang)-based diaphoretic formulas; in autumn and winter, do not administer Cinnamomi Ramulus (Guizhi)-based exterior-releasing formulas. In summer, do not administer Da Qinglong Tang (Great Blue Dragon Decoction); in winter, do not administer Baihu Tang (White Tiger Decoction).
[Pulse] The pulse is deficient with body fever, or floating with spontaneous sweating. Spontaneous sweating occurs because Fire pathogen agitates and scatters the fluids.
[Etiology] Summer Fire is excessively hot, damaging the Yuan Qi (Original Qi) of Lung Metal. There are two ways of contracting the pathogen: Contracting through activity usually affects hardworking individuals; physical exertion causes Yang to rise and Fire to prevail, leading to Heat injuring Qi, resulting in a洪大 (Hongda, surging and large) pulse. Contracting through stillness usually affects leisurely individuals; stillness allows Dampness to prevail, with Fire overcoming the position of Metal, resulting in a沉实 (Chenshi, deep and solid) pulse.
[Syndrome and Treatment] Summer-heat tends to enter the Heart channel. Entering the Heart causes choking sensation and coma/unconsciousness; entering the Liver causes dizziness; entering the Lung causes asthma, chest fullness, and flaccidity; entering the Spleen causes lethargy and unconscious sleep; entering the Kidney causes Xiao Ke (Wasting-Thirst syndrome). The disease manifests as lassitude, desire to lie down, limbs unable to hold themselves, insufficient spirit, weak legs, headache, aversion to heat, irritability, intense thirst with desire to drink, and profuse sweating. For cases contracted through activity, Baihu Jia Renshen Tang (White Tiger Decoction plus Ginseng) is the main formula. If there is headache, aversion to cold, stiffness, joint pain, high fever, and no sweat, it indicates a different pattern. For cases contracted through stillness, Dashun San (Great Harmony Powder) or Baihu Jia Cangzhu Tang (White Tiger Decoction plus Atractylodes Macrocephala Rhizome) are used. In extreme cases where Yin overcomes Yang, transmitting to Liver and Kidney causing Wei Jue (Flaccidity-Jue syndrome), Qingshu Yiqi Tang (Clear Summer-heat and Tonify Qi Decoction) is used.
For those who die from heatstroke, cold water or cool places must strictly be avoided. Hot water should be poured over them, and Huanglong Wan (Yellow Dragon Pill) is indicated.
For Heart deficiency with summer-heat injury, manifesting as body fever, headache, irritability, fullness, and thirst, Wuling San (Five Ling Powder) is used. For Lung deficiency with summer-heat injury, manifesting as body fever, irritability, stuffiness, and asthma, Baihu Tang (White Tiger Decoction) is used. For Spleen deficiency with summer-heat injury, leading to Nue (Intermittent Fever/Malaria), Changshan Yin (Changshan Decoction) is commonly used.
Huanglian Xiangru Tang (Coptis and Elsholtzia Decoction): Treats summer-heat. Add Banxia (Pinellia Rhizome) if accompanied by Phlegm; add Renshen (Ginseng) and Gancao (Licorice Root) if deficient.
Qingshu Yiqi Tang (Clear Summer-heat and Tonify Qi Decoction): Treats summer-heat injuring Lung Qi, especially in severe deficiency.
Yulong Wan (Jade Dragon Pill): Previously used to treat summer-heat. Made from oil-fried Banxia (Pinellia Rhizome) rolled in Ginger Juice.
Buzhong Yiqi Tang (Tonify the Middle and Augment the Qi Decoction): Treats Zhuxia (Summer-heat fatigue syndrome) with Phlegm-Damp leakage.
Er Ling Tang (Two Poria Decoction): Treats the transition between spring and summer, where symptoms resemble Taiyang disease (Cold Damage), with spontaneous sweating, heavy body, and pain making turning difficult. This is named Zhong Shi (Dampness Strike).
Prescription: Ze Xie (Alisma Rhizome, 1 liang), Huashi (Talcum, 2 liang), Fuling (Poria), Zhuling (Polyporus), Baizhu (Atractylodes Macrocephala Rhizome, 0.5 liang).
For Summer-Wind with Fire and excess Phlegm, emesis (Tu Fa) can be used.
