五脏有五声，心声为言，若儿稍长，应语而语迟，由在胎时，母卒惊怖，内动
儿脏，邪乘于心，心气不和，舌本无力，故语迟也。

〔钱〕病吐泻及大病后，虽有声而不能言，又能咽药，此非失音，为肾怯不能上
接于阳故也，当补肾地黄丸主之。失音，乃猝病耳。口噤不止，则失音，声迟亦同。

生，去生更远。不可不知也。
《明堂》治五六岁儿不语者，灸心俞三壮。庄氏，灸两足踝各三壮。
五脏对应五种声音，心所主的声音是言语。如果儿童年龄稍长，到了该说话的时候却说话迟缓，这是因为在胎儿时期，母亲突然受到惊吓恐惧，导致邪气内动胎儿脏腑，邪气乘袭于心，致使心气不和，舌根无力，因此出现语言发育迟缓。
〔钱乙〕菖蒲丸：治疗小儿心气不足，五至六岁仍不能说话。
配方：石菖蒲（三钱）、人参（切去芦头，焙干，半两）、丹参（二钱）、天门冬、麦门冬（去心，焙干，各一两）、赤石脂（三钱）。
《直指方》中还有当归、川芎、朱砂。
以上药物共同研为细末，用炼蜜制成如绿豆大或麻子大的丸剂。温水送服五至七丸，多则一二十丸，不限时间，每日服用三至四次。长期服用可取效。又有病后肾虚导致不语的，应当兼服钱氏地黄丸。张元素（海藏）说：地黄丸补益足少阴肾经，与菖蒲丸上下经络相通。
〔张元素〕菖蒲丹：治疗数岁仍不能说话。
配方：菖蒲（一寸九节的）、远志（去心）、桂心、人参（去芦）、黄连（去须）、酸枣仁（各半两）。
以上药物研为细末，用炼蜜调和，制成如芡实大小的丸剂。每次服用一至二粒，用生姜汤煎化送下，不限时间。
《圣惠方》治疗舌根无力、语言迟缓的芍药散：
配方：赤芍药（一两）、黄芪（七钱半）、犀角（镑片）、槟榔、甘草（炙至微红，各半两）。
以上药物研为末。每次服用一钱，用水一小盏，煎至五分，去渣，根据患儿情况调整剂量，温服。
〔钱乙〕患吐泻及大病之后，虽然有声带发声能力但不能说话，且能吞咽药物，这不是失音，而是因为肾气虚弱不能上接于阳气所致，应当用补肾地黄丸主治。失音，乃是突发疾病所致。口噤不止，就会导致失音，语言迟缓也是同理。
鸡头丸：治疗小儿各种疾病后不能说话。
配方：雄鸡头（一个，炙烤）、鸣蝉（三个，炙烤）、大黄（取结实部分，用湿纸包裹，煨熟）、甘草（锉碎、炙烤，各一两）、黄芪（切片、焙干）、川芎、远志（去心）、麦门冬（去心）、当归（去芦头，焙干，各七钱半）、人参（去芦头）、木通（各半两）。
以上药物共同研为细末，用炼蜜制成如小豆大小的丸剂。清晨用米饮送服五丸，空腹服用，每日三至四次，年龄较大的儿童可适当增加剂量。长期服用可取效。鸡和蝉这两种药材，宜寻找自然死亡的来使用，不可现杀，正如孙思邈所说：“杀生以求生，离生的道理更远。”这一点不可不知道。
The Five Zang organs correspond to five vocalizations; the heart governs speech. If a child, upon reaching an appropriate age for speaking, exhibits delayed speech development, it is because during the fetal period, the mother experienced sudden fright or terror, causing internal disturbance of the fetus's Zang organs. Pathogenic factors invade the heart, leading to disharmony of Heart Qi and weakness at the root of the tongue, thus resulting in delayed speech.
[Qian Yi] Shichangpu Wan (Acorus Pill): Treats pediatric deficiency of Heart Qi, where a child aged five or six cannot speak.
Ingredients: Shi Chang Pu (Rhizoma Acori Tatarinowii) (3 qian), Ren Shen (Radix Ginseng) (trimmed of rhizome, dried, 0.5 liang), Dan Shen (Radix Salviae Miltiorrhizae) (2 qian), Tian Men Dong (Herba Asparagi) and Mai Men Dong (Tuber Ophiopogonis) (decored of heart, dried, each 1 liang), Chi Shi Zhi (Lapis Kaolinis) (3 qian).
*Zhizhi Fang* includes Dang Gui (Radix Angelicae Sinensis), Chuan Xiong (Rhizoma Chuanxiong), and Zhu Sha (Cinnabaris).
Grind all ingredients into fine powder. Mix with refined honey to form pills the size of mung beans or sesame seeds. Administer 5–7 pills, up to 10–20 pills, with warm water, at any time. Take three to four times daily. Long-term administration yields results. For cases of mutism due to Kidney deficiency following illness, Qian Shi Di Huang Wan (Kidney-Nourishing Rehmannia Pill) should be taken concurrently. Zhang Yuansu (Haizang) stated that Di Huang Wan tonifies the Foot-Shaoyin (Kidney) meridian, working in conjunction with Shichangpu Wan to unblock the upper and lower meridians.
[Zhang Yuansu] Shichangpu Dan (Acorus Pill): Treats inability to speak after several years of age.
Ingredients: Shi Chang Pu (Rhizoma Acori Tatarinowii) (one cun, nine joints), Yuan Zhi (Radix Polygalae) (decored of heart), Gui Xin (Cortex Cinnamomi), Ren Shen (Radix Ginseng) (trimmed of rhizome), Huang Lian (Rhizoma Coptidis) (trimmed of roots), Suan Zao Ren (Semen Ziziphi Spinosae) (each 0.5 liang).
Grind into fine powder. Mix with refined honey to form pills the size of a Chinese quince seed. Take one to two pills per dose, dissolved in decoction of fresh ginger, at any time.
*Shenghui Fang* treats weak tongue root and delayed speech with Shaoyao San (Peony Powder):
Ingredients: Chi Shao Yao (Radix Paeoniae Rubra) (1 liang), Huang Qi (Radix Astragali) (0.75 liang), Xi Jiao (Cornu Rhinocerotis) (sliced), Bing Lang (Arecae Semen), Gan Cao (Radix Glycyrrhizae) (stir-fried until slightly red, each 0.5 liang).
Grind into powder. Take 1 qian per dose with one small cup of water, decocted to half a cup. Strain and administer warm, adjusting dosage according to the child’s condition, without strict timing restrictions.
[Qian Yi] After vomiting, diarrhea, or severe illness, if the child has voice but cannot speak, yet can swallow medicine, this is not aphonia (loss of voice). It is caused by Kidney deficiency failing to connect upward with Yang Qi. It should be treated primarily with Bu Shen Di Huang Wan (Kidney-Tonifying Rehmannia Pill). Aphonia results from acute illness. Persistent trismus (lockjaw) leads to aphonia; delayed speech is similar in nature.
Jitou Wan (Chicken Head Pill): Treats post-illness mutism in children.
Ingredients: Xiong Ji Tou (Caput Galli Masculini) (one, roasted), Ming Chan (Periostracum Cicadae) (three, roasted), Da Huang (Radix et Rhizoma Rhei) (solid part, wrapped in wet paper, baked until cooked), Gan Cao (Radix Glycyrrhizae) (chopped, stir-fried, each 1 liang), Huang Qi (Radix Astragali) (sliced, dried), Chuan Xiong (Rhizoma Chuanxiong), Yuan Zhi (Radix Polygalae) (decored of heart), Mai Men Dong (Tuber Ophiopogonis) (decored of heart), Dang Gui (Radix Angelicae Sinensis) (trimmed of rhizome, dried, each 0.75 liang), Ren Shen (Radix Ginseng) (trimmed of rhizome), Mu Tong (Caulis Akebiae) (each 0.5 liang).
Grind all into fine powder. Mix with refined honey to form pills the size of adzuki beans. In the morning, take five pills with rice water on an empty stomach. Take three to four times daily; increase dosage for older children. Long-term administration yields results. For chicken and cicada, use naturally deceased specimens; do not kill them freshly. As Sun Simiao said, "Killing life to seek life moves further away from life." This must be known.
*Mingtang* treats mutism in five-to-six-year-old children by moxibustion on Xin Shu (BL-15), three moxa cones. Zhuang’s method advises moxibustion on both ankles, three cones each.
