经曰∶太阳中热， 是也。其证初起，面垢身热自汗，烦躁不安，唇舌皆赤，气出如
火，小便赤涩，口中大渴。此证常见夏秋。
按∶此条在藜藿之儿多有之，以其坐卧烈日之中，澡浴寒涧之内，以致暑气入里，内热外寒，故见以前诸证。
医者见其身热自汗，口渴烦躁，疑为惊风，妄用风药，反燥其血，以致心中噎闷，昏不知人，甚则反张搐搦，
皆由血不荣筋，烦热过甚之故也。若膏粱之儿，不涉长途，不经酷日，暑证尚少，何有暑风？若谓高堂广厦，口
餐生冷，身纳风凉而得之者，即伤寒之类，又何暑之可称？
古人谓暑伤心，其实心不可伤，伤之必死。盖心为君主之官，虚灵湛寂，神性居之，邪不易犯。止因六气
之中，以暑配君火，故曰暑伤心，然所犯者心包络耳。包络为心之宫阙，捍蔽外邪，不容轻侮，惟由暑热摇撼
外郭，故神志为之昏惑。但泻其太阳丙火，则少阴君主神志自宁矣。宜却暑丹。
却暑丹 治小儿伤暑，误用风药，致心神昏闷，烦躁不安，甚则搐搦。

The *Yellow Emperor's Inner Classic* states: "Taiyang (Bladder/Governing Vessel channel) suffering from heat evil" refers to this condition. The initial symptoms include a greasy appearance of the face, fever, spontaneous sweating, restlessness and irritability, redness of the lips and tongue, breath that feels like fire, dark and scanty or painful urination, and extreme thirst in the mouth. This syndrome is commonly seen in summer and autumn.
Commentary: This description applies frequently to children from commoner families, as they sit under the scorching sun or bathe in cold streams, causing summer-heat to penetrate inward. This results in internal heat with external cold, manifesting as the aforementioned symptoms.
When physicians observe fever, spontaneous sweating, thirst, and irritability, they may suspect infantile convulsion (Jing Feng) and recklessly administer wind-dispelling herbs. This inadvertently dries up the blood, leading to chest oppression, coma, and even opisthotonos (back arching) and spasms. These complications arise because the blood fails to nourish the sinews due to excessive irritant heat. For children of wealthy families who do not endure long journeys or exposure to intense sun, summer-heat syndromes are rare; thus, where would "summer-heat wind" come from? If one claims that illness arises from living in spacious halls, consuming raw/cold foods, and being exposed to wind and cool air, such cases belong to Cold Damage (Shang Han) categories, and should not be termed summer-heat.
Ancients stated that summer-heat damages the Heart. In reality, the Heart itself cannot be damaged; if it were, death would ensue. The Heart is the Sovereign Official, characterized by emptiness, spirituality, clarity, and tranquility, housing the Shen (Spirit), making it resistant to pathogenic invasion. However, since summer-heat is paired with Ministerial Fire among the Six Qi (Wind, Cold, Summer-Heat, Dampness, Dryness, Fire), it is said that "summer-heat damages the Heart." Actually, what is invaded is the Pericardium (Xin Bao Luo). The Pericardium serves as the palace wall of the Heart, defending against external evils. It is not easily violated. Only when summer-heat shakes the outer defenses does the Shen become confused and disoriented. By clearing the Bing Fire of the Taiyang (Small Intestine channel), the Shen of the Shaoyin (Heart/Kidney channel) Sovereign will naturally calm. Que Shu Dan (Summer-Heat Repelling Pill) is indicated.
Que Shu Dan (Summer-Heat Repelling Pill): Treats pediatric summer-heat injury caused by the mistaken use of wind-dispelling herbs, resulting in mental confusion, chest oppression, restlessness, and potentially spasms.
