论曰心为言，肝为语，其经属手少阴足厥阴。其气上通于舌，舌者声之机，若禀受之初
。母怀惊怖，则子之心火不足，而肝木弱，故令机关不利，气不宣扬而语迟。甚者有经数岁
不能言者。

论曰牙齿者，是骨之所终，髓之所养，手阳明足太阳之脉，并入于齿。若血气充实，则

令生者，或龋或虫落，不能复生也。

论述：心主言语，肝主话语，其经络归属于手少阴心和足厥阴肝。气血上通于舌，舌是发声的关键机关。如果在胎儿禀受之初，母亲受到惊吓恐惧，就会导致胎儿心火不足，肝木虚弱，从而使得发声机关不利，气机不能宣发畅达，导致语言发育迟缓。严重的甚至经过数年仍不能说话。

赤芍药（一两） 黄芪（锉碎三分） 犀角（镑片） 槟榔（锉碎） 甘草（炙制各半两）

论述：牙齿是骨骼的终点，由骨髓滋养，手阳明大肠经和足太阳膀胱经的脉气，都并入于牙齿。如果气血充实，则骨髓强盛，即使牙齿损坏脱落，仍然能够再生。如果体质虚弱，气血衰耗，风冷邪气侵袭，导致牙齿长期不生。假使长出的牙齿，或者蛀蚀或者虫落，也不能再重新生长。

牛粪中的黑豆
以上一味药，取十四枚，轻轻剥去顶端的皮，用豆子顶端开口处涂抹在牙根上，经常使用应当有效。

Commentary: The Heart governs speech (Yan), and the Liver governs discourse (Yu); their meridians belong to the Hand-Shaoyin (Heart) and Foot-Jueyin (Liver). Their Qi connects upward to the tongue, which is the mechanism of voice. If, at the time of initial endowment, the mother experiences fright or terror, it results in insufficient Heart Fire and weak Liver Wood in the child. Consequently, the mechanisms become uncoordinated, Qi fails to circulate freely, leading to delayed speech. In severe cases, a child may be unable to speak for several years.

Commentary: Teeth are the culmination of bones and are nourished by marrow. The meridians of Hand-Mingyang (Large Intestine) and Foot-Taiyang (Bladder) enter into the teeth. When Blood and Qi are abundant, marrow is strong; even if teeth are damaged or fall out, they can regenerate. If the body is weak, Blood and Qi are depleted, and Wind-Cold pathogens invade, causing teeth to fail to emerge for a long time. Even if they do emerge, they may suffer from caries or decay and cannot regenerate properly.
Formula for treating children whose teeth do not grow or have failed to regrow after falling out:
Heidou within cow dung (Black beans found in cow manure)
Take fourteen beans of this type. Gently remove the skin from the tip. Apply the open tip of the bean to the tooth root repeatedly. This method should be effective.
Formula for treating children whose teeth do not grow:
Xiongshufen (Feces of male mouse, 14 units)
Use one fecal pellet daily to wipe the tooth root. After twenty-one days, the teeth should emerge.
Another Formula:
Daoliang Yidaoli (Rice grains left by the roadside)
Apply this grain to the site of the lost tooth thirty-seven times. The tooth will naturally grow.
Divine Effect Formula for treating children whose teeth do not grow, effective regardless of duration:
Xiongjifen (Feces of male chicken, 14 units with pointed heads) Cijifen (Feces of female chicken, 14 units with round heads)
Burn the above two substances to ash while preserving their medicinal properties. First, use a needle to gently open the gum tissue, then apply the chicken feces ash to the area.
