经曰∶头者，六阳之会，诸阳所凑也。头为髓之海，若大热则髓溢汗泄，或颅囟肿起，
或头缝开解，或头疮目疾。俗云∶头无凉头，故头宜凉。
心属丙火，若外受客热，内接心火，则内外俱热也。其证轻则口干，舌燥，腮红面赤；
重则啼叫惊跳，故
心宜凉。
小儿忽见非常之物，或见未识之人，或闻鸡鸣犬吠，忽见牛马等畜，或嬉戏惊骇，或
忽闻大声，因而作搐者，缘心气乘虚而精神离散故也。当用补心益气药治之。如用镇心牛黄、
朱砂、琥珀、金银、脑、麝、水银等药，则成慢惊风搐，以致腹胀足冷，不能疗也。
经曰∶脾为黄婆，胃为金公，主养五脏六腑。若脾胃全固，则津液通行，气血流畅，表里
冲和，一身康健。盖脾胃属土而恶湿。小儿变蒸，上唇肿而头热，或上气身热，父母不晓，
妄作伤寒伤食治之，或以解药出汗，或以通药宣泄，或以凉药镇心，或以帛汤振缴，致令冷热
不调，内伤脾胃，搏于大肠，故粪便清色。久不已者，必吐，吐不已者作搐。搐作又言热则生
风，转用凉药治之，愈觉败伤真气，渐不救者多矣。经云∶脾土虚弱，肝木乘之，故筋挛而作
搐，宜用补脾温胃畅气之药治之，庶可得其生也。
小儿在胎之时，其母取凉过度，冷气入于胞胎之中，儿生之后，因悲啼未定，便与乳食，
使气与食蓄结于中，久而不散，致伤脾胃。轻则呕奶粪青，重则腹中气鸣，气逆，涎潮流溢，
以致难治。
《黄帝内经》说：足部由足阳明胃经所主管，寒气容易从下部侵入，所以要保证足部温暖。
《黄帝内经》说：头部是六条阳经交汇之处，所有阳经都汇聚于此。头又是髓海所在，如果头部过热，会导致髓液外溢、汗出过多，或者出现囟门肿起，或者头骨缝隙裂开，或者发生头疮和眼疾。俗话说“头不能受凉”，所以头部适宜保持凉爽。
心在五行中属丙火，如果外部受到客热侵袭，内部又与心火相接，就会导致内外皆热。其症状轻则表现为口干、舌燥、两腮发红、面色赤红；重则表现为啼哭惊跳，所以心脏适宜保持凉爽。
小儿突然见到不寻常的事物，或者看见不认识的人，或者听到鸡鸣狗叫，忽然看到牛马等牲畜，或者因嬉戏而受惊骇，或者突然听到巨大的声响，因而引发抽搐的，这是因为心气虚弱导致精神离散所致。应当使用补益心气的药物进行治疗。如果使用镇心安神的牛黄、朱砂、琥珀、金银、冰片、麝香、水银等药物，反而会导致慢惊风抽搐，进而引起腹部胀满、足部发冷，这就无法治愈了。
《黄帝内经》说：脾被称为“黄婆”，胃被称为“金公”，它们主要负责滋养五脏六腑。如果脾胃功能坚固，那么津液就能通畅运行，气血流畅，表里调和，全身健康。因为脾胃属土，而厌恶湿气。小儿在“变蒸”（婴幼儿生长发育过程中的生理现象）期间，会出现上唇肿胀、头部发热，或者气逆身热的情况，父母如果不了解这些情况，错误地当作伤寒或伤食来治疗，或者用解表药发汗，或用通下药泻下，或者用凉药清心，或者用热水擦拭身体，导致冷热失调，内伤脾胃，邪气搏结于大肠，所以粪便颜色清稀。如果长期不好，必然呕吐，呕吐不止就会引发抽搐。抽搐发作时，人们又说热极生风，转而使用凉药治疗，这更加败坏了真气，逐渐无法挽救的情况很多了。经书说：脾土虚弱，肝木乘虚克制它，所以筋脉拘挛而引发抽搐，应当使用补脾、温胃、畅达气机的药物治疗，这样才可能获得生机。
小儿在母胎之中时，如果母亲过度贪凉，冷气进入胞胎之中，婴儿出生后，因为悲伤啼哭尚未平定，就立即给予乳食，使得气与食物蓄积结滞在体内，时间久了不能消散，从而损伤脾胃。轻则表现为吐奶、大便发青，重则表现为腹中肠鸣、气逆、涎水直流溢出，以致难以治疗。
The *Classic of Medicine* states: The feet are governed by the Foot-Yangming Stomach Meridian. Cold pathogens arise from below; therefore, it is essential to keep the feet warm.
The *Classic of Medicine* states: The head is the convergence point of the six Yang meridians, where all Yang channels assemble. The head is also the "Sea of Marrow." If excessive heat occurs in the head, marrow may overflow and sweat may leak profusely, or the fontanelle may swell, or the cranial sutures may separate, or sores on the head and eye diseases may arise. As the common saying goes, "the head should not be cooled," thus the head is suited to remain cool.
The Heart belongs to Bing Fire (Yang Fire). If external pathogenic heat invades and internal Heart fire connects with it, both interior and exterior will become hot. Mild symptoms include dry mouth, dry tongue, reddening of the cheeks, and flushed face; severe symptoms include crying, jumping, and fright. Therefore, the Heart is suited to remain cool.
If a child suddenly sees unusual objects, unfamiliar people, hears chickens crowing or dogs barking, suddenly sees cattle or horses, or is frightened during play, or suddenly hears a loud noise, leading to convulsions, this is due to the deficiency of Heart Qi causing the dispersion of spirit and mind. Treatment should employ herbs that tonify the Heart and benefit Qi. If sedative and heart-calming herbs such as Niuhuang (Calculus Bovis), Zhusha (Cinnabaris), Hupo (Succinum), Jinyin (Gold and Silver foil), Naobing (Borneolum Syntheticum), Shexiang (Moschus), and Shuiyin (Hydrargyrum) are used, it may result in slow convulsive disease (Man Jing Feng), leading to abdominal distension and cold feet, rendering the condition incurable.
The *Classic of Medicine* states: Spleen is referred to as "Huang Po" (Yellow Matron), and Stomach as "Jin Gong" (Golden Duke); they are responsible for nourishing the five Zang and six Fu organs. If the Spleen and Stomach are firmly established, then body fluids circulate freely, Qi and Blood flow smoothly, the exterior and interior are harmonious, and the whole body remains healthy. Since Spleen and Stomach belong to Earth and dislike dampness, when infants undergo "bian zheng" (physiological changes during growth), they may exhibit swelling of the upper lip, fever in the head, or qi rebellion with body heat. Parents who do not understand this may mistakenly treat it as Taiyang disease (Cold Damage) or food stagnation, using diaphoretic drugs to induce sweating, purgative drugs to drain downward, cooling drugs to calm the Heart, or hot water baths to shake off chill. This leads to imbalance of cold and heat, internal injury to the Spleen and Stomach, and pathogenic factors combing with the Large Intestine, resulting in clear-colored stools. If prolonged, vomiting will occur; if vomiting persists, convulsions will follow. When convulsions occur, it is often said that extreme heat generates wind, leading to the use of cooling drugs. This further damages true Qi, and many cases become irrecoverable. The classics state: When Spleen Earth is weak, Liver Wood overacts upon it, causing tendon spasms and convulsions. Treatment should employ drugs that tonify the Spleen, warm the Stomach, and promote the free flow of Qi, thereby offering a chance of survival.
When a fetus is in the womb, if the mother excessively seeks coolness, cold qi enters the fetal sac. After birth, if the infant is fed milk or food while still crying from grief without having settled, the Qi and food accumulate and knot in the middle jiao. Over time, this fails to dissipate, injuring the Spleen and Stomach. Mild cases present with regurgitation of milk and green stools; severe cases present with borborygmus in the abdomen, qi rebellion, and overflowing saliva, making treatment difficult.
