幼小之病，稍大者能言，若数月婴孩有病不能告人，人何以知其喉痛也，当细察其形。
每吮乳便啼哭，或不能吮乳，必令抱儿与明亮处仰其头，以箸按其舌根（竹箸恐其擢喉，或
以手指剪去指甲，将指头按舌更妙），看喉中有何形色红肿否，并看明舌上两边及上 、牙
龈诸处，或生上 痈，或锁喉毒，兜腮痈、木舌、重舌、重 、重龈、马牙、鹅口疮之类，
务看明白，以便查照各部，按法施治，不容稍缓。婴儿脏腑娇嫩，最不耐病，且以乳为命，
不能吮乳，延至二三日，胃中空虚，虽服对症之药，若无胃气营运，多难见功。胃气一绝，
神丹不可为矣。如系喉症，急以指头剪去指甲，更要剪去尖锋，磨光磨平（以免擢伤婴孩喉
舌），将元珠丹粘在指头上，用指轻轻搽入婴孩口内，或又搽在乳母乳上使其咽下，频频搽
之，喉症即愈。稍重者，将煎方令乳母代服之，以喉愈为度。鸡、鱼、姜、椒、羊肉、辛热
发物，乳母必须禁口。幼小婴孩口不能言，务要刻刻看视，不可稍为疏忽。用久制人中黄泡
水灌之奇效。或用绸绢将人中黄包裹如橄榄式泡湿，就向婴儿口边如吮乳样，亦妙。
其人平日常有咽干、喉燥、齿痛、舌痛、夜热、夜咳之症，偶然受热，或食热物，或犯
房劳，即患咽喉疼痛、红肿、或红甚而不肿，夜甚于昼，脉洪数或细数。此阴虚也，皆由肾
中真阴亏损。人之肾中有水有火，水即真阴，火即真阳，所云相火、龙火，即此火也。水火
同宫，水不亏足以济火，足以制火，火藏水中，自不为患；水一亏，则火无所济，而无所制

为咽痛，故名阴虚喉痛。虽皆由于火，而阴阳虚实与阳症喉痛又有分别。阳症之火，起于六
腑阳分，是后天有余之火，实火也，故用苦寒咸寒以直折之；阴虚之火，起于肾经阴分，是

幼童患病，稍大一些的孩子能够表达，如果是几个月的婴儿生病无法告知他人，人们如何知道他是喉痛呢？应当仔细观察他的形态。
每次吃奶时就啼哭，或者不能吸吮乳汁，一定要抱着孩子到明亮处仰起他的头，用筷子按压舌根（竹筷恐怕会划伤喉咙，或者用手指剪去指甲，用手指头按压舌头更好），查看喉咙中是否有形色红肿，并看清楚舌上两边及上颚、牙龈各处，或者生有上颚痈，或者锁喉毒，兜腮痈、木舌、重舌、重腭、重龈、马牙、鹅口疮之类，务必看清楚，以便对照各部，按照方法施治，不容许丝毫迟缓。婴儿脏腑娇嫩，最不耐受疾病，且以乳为命，如果不能吸吮乳汁，拖延两三天，胃中空虚，虽然服用对症的药物，如果没有胃气运化，大多难以见效。胃气一旦断绝，神丹妙药也无法救治了。如果是喉症，急忙用手指剪去指甲，更要剪去尖锋，磨光磨平（以免划伤婴孩喉舌），将元珠丹粘在指头上，用手指轻轻搽入婴孩口内，或者又搽在乳母乳头使其咽下，频繁搽之，喉症即可痊愈。稍重的，将煎好的方剂让乳母代服，以喉愈为度。鸡、鱼、姜、椒、羊肉、辛热发物，乳母必须禁口。幼小婴孩口不能言，务必时刻看护，不可稍有疏忽。用久制的人中黄泡水灌服奇效。或者用绸绢将人中黄包裹如橄榄式泡湿，就向婴儿口边如吮乳样，也很好。
其人平日常有咽干、喉燥、齿痛、舌痛、夜热、夜咳的症状，偶然受热，或食热物，或犯房劳，即患咽喉疼痛、红肿、或红甚而不肿，夜间比白天严重，脉洪数或细数。这是阴虚，皆由肾中真阴亏损。人的肾中有水有火，水即真阴，火即真阳，所说的相火、龙火，就是此火。水火同宫，水不亏足以济火，足以制火，火藏水中，自然不为患；水一亏，则火无所济，而无所制，遂得逞其炎上之性。肾的脉络挟咽，循喉咙，系舌本，火不藏源，热必循经络浮越上冲而为咽痛，故名阴虚喉痛。虽皆由于火，而阴阳虚实与阳症喉痛又有分别。阳症之火，起于六腑阳分，是后天有余之火，实火也，故用苦寒咸寒以直折之；阴虚之火，起于肾经阴分，是先天不足之火，虚火也，不宜苦寒，惟大补其水以济之以制之，并引导敛纳之策是矣，宜用六味地黄汤加麦冬、五味，或加酒浸大生地、玄参、酒蒸怀牛膝。愈后以六味地黄汤、人参固本丸酌量加减，常久服之，并戒酒色、新鸡、子鸭、鱼、虾一切助火之物，能清心寡欲，药始有效，否则不免反复难治。
In infants and young children, those slightly older can speak; if a few-month-old infant is ill and cannot communicate, how can one know they have throat pain? One must carefully observe their physical condition.
If the infant cries every time they attempt to suckle milk, or are unable to suckle, hold the child in a bright place and tilt their head back. Press the root of the tongue with chopsticks (bamboo chopsticks may scratch the throat; alternatively, trim fingernails and use fingertips to press the tongue, which is better). Inspect the throat for any redness, swelling, or discoloration, and clearly examine both sides of the tongue, the hard palate, gums, etc. Look for conditions such as hard palate abscesses, lock-throat toxins, cheek-swelling abscesses, wooden tongue, double tongue, double palate, double gums, horse teeth, or thrush. It is essential to identify these clearly to consult relevant sections and apply appropriate treatments without delay. Infants have delicate internal organs and are least tolerant of disease. Since milk is their life source, inability to suckle for two or three days leads to an empty stomach. Even if correct medicine is administered, without the functioning of Stomach Qi (Stomach Energy) to transport and transform, it will likely be ineffective. Once Stomach Qi is exhausted, even divine elixirs cannot save them. If it is a throat condition, quickly trim fingernails, remove sharp edges, and smooth them (to avoid injuring the infant's throat and tongue). Adhere Yuanzhu Dan (Pearl Pearl Pill) to the fingertip and gently apply it inside the infant's mouth, or apply it to the lactating mother's nipple for the infant to swallow. Frequent application will cure the throat condition. For slightly severe cases, have the lactating mother take the decoction until the throat heals. The mother must avoid chicken, fish, ginger, pepper, mutton, and other spicy, hot, or stimulating foods. Since infants cannot speak, constant vigilance is required; negligence is not permitted. Administering water infused with Jiuzhi Renzhonghuang (Aged Human Excrement Powder) yields miraculous results. Alternatively, wrap Renzhonghuang in silk like an olive, moisten it, and offer it to the infant's mouth as if breastfeeding, which is also excellent.
The person often experiences dry throat, dry pharynx, toothache, tongue pain, night fever, and night cough. Occasionally exposed to heat, consuming hot foods, or engaging in sexual excess, they develop sore throat with redness and swelling, or intense redness without swelling, worsening at night compared to day. The pulse is surging and rapid (Hong Shu) or fine and rapid (Xi Shu). This is Yin Deficiency, caused by the depletion of True Yin in the Kidneys. In the Kidneys, there is Water and Fire; Water is True Yin, and Fire is True Yang. What is called Ministerial Fire (Xiang Huo) or Dragon Fire (Long Huo) refers to this Fire. Water and Fire reside in the same palace; sufficient Water nourishes and controls Fire, keeping Fire hidden within Water so it causes no harm. When Water is depleted, Fire lacks nourishment and control, allowing its flaming-upward nature to prevail. The Kidney meridians flank the pharynx, follow the throat, and connect to the root of the tongue. When Fire does not stay rooted, heat floats up along the meridians and rushes upward, causing sore throat; hence it is named Yin Deficiency Throat Pain. Although all stem from Fire, there are distinctions between Yin-Yang, deficiency-excess, and Yang-pattern throat pain. Fire in Yang patterns arises from the Yang aspect of the Six Fu Organs; it is acquired excessive Fire, i.e., Excess Fire. Thus, bitter-cold and salty-cold herbs are used to directly suppress it. Fire in Yin patterns arises from the Yin aspect of the Kidney Meridian; it is congenital insufficient Fire, i.e., Deficient Fire. Bitter-cold herbs are inappropriate. Instead, one should greatly tonify Water to nourish and control it, employing strategies to guide and consolidate it. Suitable formulas include Liuwei Dihuang Tang (Six-Ingredient Rehmannia Decoction) added with Maidong (Ophiopogon Root) and Wuweizi (Schisandra Berry), or added with Jiujin Dadihuang (Wine-soaked Large Rehmannia Root), Xuanshen (Scrophularia Root), and Jiuzheng Huainiuxi (Wine-steamed Huai Achyranthes Root). After recovery, adjust Liuwei Dihuang Tang and Renshen Guben Wan (Ginseng Solidifying Root Pill) according to the condition, taking them long-term. Avoid alcohol, sexual indulgence, new chicken, ducklings, fish, shrimp, and all fire-assisting foods. Cultivating a clear mind and reducing desires is necessary for the medicine to be effective; otherwise, relapse and difficult treatment are inevitable.
