小儿中有不能说话的，其证候有三种。一是心气不足。心经的系脉连于舌根，气充盛则推动舌根运动，于是发出声音说话。现在气虚怯弱，不能滋养运用舌体，所以不能说话。这个证候已经在“五气”条目下详细记载了。二是突然不能说话，这是因为风寒邪气，侵袭哑门穴，联系到舌根，使舌根拘急紧张，所以突然不能说话。还有一种证候，喉咙是气息通行的道路，会厌是声音发出的门户，突然被风邪客居于喉部和会厌，导致失音而发不出声音，这并不是真的不能说话。三是病后不能说话，这是因服用清热药以利小便，导致肾虚而不能上接阳气，所以不能说话。以前钱乙治疗王氏患慢惊风病愈后，有声音但不能说话，众人都认为是失音。钱乙说：“既然失音，为什么能睁眼并能饮食？而且牙关不紧闭，口唇不僵硬，却能吞咽药物。”众医生都不明白。钱乙说：“这是因为用了清热利小便的药，导致肾气虚弱，不能上接于阳的缘故。”于是用地黄丸补肾，病人渐渐能说话了，一个月痊愈。该方剂原本收录在《集》中，另外收录的方剂在后面列出。

小儿中有口渴而饮水的，这是由于脏腑有热，热则脏腑干燥，所以身体多有发热、烦躁，耗伤津液，这就导致口渴，想要饮水来缓解它。又有疳积引起的口渴、吐泻引起的口渴、霍乱引起的口渴等，各自在本项下详细记载。阎孝忠说：凡是小儿各种口渴，因亡失津液而引水喝的，只要多煎煮钱乙的白术散给患儿服用，让患儿任意喝足。喝得越多越好。该方剂原本收录在《集》中。热渴的方剂叙述在后面。

There are children who cannot speak. This condition presents in three types. The first is deficiency of Heart Qi (Heart Qi). The Heart meridian connects to the root of the tongue; when Qi is sufficient, it moves the tongue root, producing speech. Now, due to deficient and timid Qi that cannot nourish and utilize the tongue, speech is absent. This syndrome has been detailed under the section on "Five Qi" (Five Pathogenic Factors related to Emotions/Organs). The second type is sudden inability to speak, caused by Wind-Cold pathogenic factors invading the Yamen (GV6) acupoint, affecting the tongue root, causing stiffness and tension of the tongue root, thus resulting in sudden aphonia. Another presentation involves the throat as the pathway for Qi and the epiglottis as the gate for sound; if suddenly invaded by Wind pathogens lodging in the throat and epiglottis, voice loss occurs without speech, which is not true aphonia. The third type is inability to speak after an illness, caused by the use of cooling herbs to promote urination, leading to Kidney Deficiency where Qi cannot ascend to connect with Yang, hence the inability to speak. Previously, Qian Yi treated a child named Wang who, after recovering from slow convulsions, had a voice but could not speak. Others considered this aphonia. Qian Yi said, "If it were aphonia, how could he open his eyes and eat/drink? Moreover, his teeth are not clenched, his mouth is not tight, yet he can swallow medicine." The other physicians did not understand. Qian Yi stated, "This is because cooling diuretics were used, depleting Kidney Qi so it cannot ascend to connect with Yang." He subsequently administered Dihuang Wan (Rehmannia Pill) to tonify the Kidney, and the child gradually regained speech, recovering fully within a month. The formula is recorded in the original collection; additional formulas are listed below.
Changpu San (Acorus Powder)
Treats sudden aphonia due to Wind-Cold invading the Yamen (GV6) acupoint.
Shichangpu (Rhizoma Acori Tatarinowii), Guixin (Cortex Cinnamomi), Yuanzhi (Radix Polygalae) [decored, boiled in Licorice Decoction, each 1 fen].

Grind into fine powder, mix with refined honey to form pills the size of small beans. Take 5 pills on an empty stomach in the morning with rice water, three times daily. Increase dosage for older children; long-term administration yields results.
Children who feel thirsty and drink water do so because of Heat in the Zang-Fu organs. Heat causes dryness in the viscera, leading to body heat and irritability, consuming Body Fluids (Jin-Ye), resulting in thirst and the desire to drink to relieve it. There are also cases of thirst due to Gan accumulation (Gan Syndrome), vomiting and diarrhea, or Huoluan (Cholera-like disorder); these are detailed in their respective sections. Yan Xiaozhong stated: For all pediatric thirst cases caused by fluid depletion leading to drinking, simply decoct Qian Yi's Baizhu San (Atractylodes Macrocephala Powder) and administer it freely. The more they drink, the better. The formula is recorded in the original collection. Formulas for Heat-Thirst are described below.
Lian Tang San (Lotus Soup Powder)
Treats infantile thirst and heart dryness. Use Qingfen (Calomelas) ground extremely fine. For infants, one zi dose; for children under three or four years old, half a qian. Mix with decocted Lotus Soup and administer. In winter when lotus flowers are unavailable, use lotus seeds instead.
