小儿髓不满骨，血不荣筋，故软弱不行，虎骨饮治之，或六味丸加牛膝、五加皮、酒
炙鹿茸亦可。若禀受肝气怯弱，致两足挛缩，
两手伸展无力，须薏苡仁丸治之。

小儿生后，头项手足肉口皆软，乃先天诸阳之气不足也，头项症地黄丸（见囟）服之，甚
者星附膏贴之。手足肉口症，补中益气汤主之（见保产）。有因吐泻之久，囟目顿陷，天柱骨
倒，补中加附子治之，地黄丸料兼服之。
余子敬曰，肉软者，肉少皮宽，口软者，食少舌舒，皆脾胃之症。又有初生，遍身赤
肉，全无皮壳，或有皮如鱼胞，如水晶，亦产母脾气不足所致。无皮者，以粳米粉拌黄
土敷之。鱼胞水晶者，蜜陀僧碾细末敷之。更有 赤发热者，石膏碾细敷之。

薛氏曰∶五硬者，仰头取气，难以动摇，气壅作痛，连于胸膈，脚手心冷而硬，此阳
气不营于四末也。又曰∶手足冷而硬者，独阳无阴也，难治。若肚筋青急，为木乘土位，
速宜六君子汤，加炮姜、肉桂、升麻、柴胡，以复其真气。如系风邪客于四末，而令硬冷
者，须从惊风症中求之。
六君子汤
人参 白术 茯苓 陈皮 半夏 炙甘草
小儿骨髓未充盈骨骼，血液不能滋养筋脉，因此肢体软弱无法行走，可用虎骨饮治疗，或者使用六味丸加入牛膝、五加皮、酒炙鹿茸也可以。如果是先天禀受肝气怯弱，导致两足挛缩，两手伸展无力，必须用薏苡仁丸治疗。
虎骨饮
虎胫骨 干地黄 当归身 枣仁 茯苓 川芎 防风 牛膝 肉桂
研为细末，每次服用一钱，用米粥汤调服并加入少许酒，每日两次。
薏苡仁丸
秦艽 当归 薏苡仁 枣仁 防风 羌活
各等分制成蜜丸，大小如芡实，每次一丸，用荆芥汤研磨化开，加入麝香一厘服用。
小儿出生后，头项、手足、肌肉、口唇都显得软弱，这是先天诸阳之气不足所致，头项软弱症状服用地黄丸（见囟门章节），严重的用星附膏外贴。手足肌肉和口唇软弱症状，以补中益气汤为主治（见保产章节）。有因长期吐泻，导致囟门和眼睛突然凹陷，天柱骨倒伏，在补中益气汤中加入附子治疗，同时兼服地黄丸药料。
余子敬说，肌肉软弱的，是肌肉少皮肤宽弛；口唇软弱的，是进食少舌头松弛，这都是脾胃的病症。又有刚出生时，遍身赤红无肉，完全没有皮壳，或者有皮像鱼泡，像水晶一样透明，这也是产妇脾气不足所致。没有皮的，用粳米粉拌黄土敷贴。像鱼泡水晶那样的，用密陀僧碾成细末敷贴。更有身体发红发热的，用石膏碾细敷贴。
薛氏说：五硬的症状，是仰头呼吸，难以动摇，气机壅滞作痛，牵连胸膈，手脚心冷而硬，这是阳气不能营运于四肢末端。又说：手脚冷而硬的，是独阳无阴，难治。如果肚脐周围青筋紧急，是木邪乘克土位，速宜用六君子汤，加入炮姜、肉桂、升麻、柴胡，以恢复真气。如果是风邪客居于四肢末端，导致硬冷的，必须从惊风症中寻找病因。
Pediatric patients have marrow that fails to fill the bones and blood that fails to nourish the sinews, resulting in weakness and inability to walk. This can be treated with Hugu Yin (Tiger Bone Decoction), or Liuwei Wan (Six-Ingredient Pill with Rehmannia) added with Niuxi (Achyranthes Root), Wujia Pi (Acanthopanacis Cortex), and Lu Rong (Deer Antler) processed with wine. If the constitution is weak due to deficient Liver Qi, causing spasms and contraction of both legs and weakness in extending both hands, Yiyi Ren Wan (Coix Seed Pill) must be used for treatment.
Hugu Yin (Tiger Bone Decoction)
Hu Jing Gu (Tiger Tibia Bone), Gan Di Huang (Prepared Rehmannia Root), Dang Gui Shen (Codonopsis Root or Angelica Sinensis Root Base), Zao Ren (Ziziphus Seed), Fu Ling (Poria), Chuan Xiong (Ligusticum Rhizome), Fang Feng (Saposhnikovia Root), Niuxi (Achyranthes Root), Rou Gui (Cinnamon Bark).
Grind into fine powder. Take one qian per dose, mixed with rice gruel broth and a small amount of wine. Administer twice daily.
Yiyi Ren Wan (Coix Seed Pill)
Qin Jiao (Gentiana Macrophylla Root), Dang Gui (Angelica Sinensis Root), Yi Yi Ren (Coix Seed), Zao Ren (Ziziphus Seed), Fang Feng (Saposhnikovia Root), Qiang Huo (Notopterygium Rhizome).
Equal parts, made into honey pills the size of an Euryale Seed (Qianshi). One pill per dose, dissolved in Jingjie Decoction (Schizonepeta Decoction), with Shexiang (Musk) added.
After birth, if the infant's head, neck, limbs, muscles, and mouth appear soft, it is due to insufficiency of congenital Yang Qi. For head and neck softness,服用 Dihuang Wan (Rehmannia Pill) (see Fontanelle section); for severe cases, apply Xingfu Gao (Star Aconite Plaster). For limb muscle and mouth softness, Buzhong Yiqi Tang (Tonify the Middle and Augment the Qi Decoction) is the primary treatment (see Obstetrics section). In cases caused by prolonged vomiting and diarrhea, leading to sudden depression of the fontanelle and eyes, and collapse of the Tianzhu Bone (neck spine), add Fuzi (Aconite Lateral Root) to Buzhong Yiqi Tang, and concurrently administer Dihuang Wan ingredients.
Yu Zijing stated: Soft muscles indicate scanty flesh and loose skin; soft mouth indicates poor feeding and relaxed tongue. Both are disorders of the Spleen and Stomach. Some infants are born with red flesh all over the body, lacking skin entirely, or having skin resembling fish bladders or crystal. These are also caused by the mother's deficiency of Spleen Qi. For those without skin, apply a mixture of Jing Mi Fen (Rice Flour) and yellow earth. For those with skin like fish bladders or crystal, apply Mituo Seng (Lead Monoxide) ground into fine powder. For those with redness and fever, apply Shi Gao (Gypsum) ground into fine powder.
Xingfu Gao (Star Aconite Plaster)
Nan Xing (Pinellia Tuber Processed with Alum/Arisaema Rhizome), Fuzi (Aconite Lateral Root).
Equal parts, ground into powder, mixed with fresh Ginger Juice for topical application.
Dr. Xue stated: The symptoms of Wu Ying (Five Stiffnesses) include holding the head back to breathe, difficulty in movement, qi stagnation causing pain radiating to the chest and diaphragm, and cold, stiff palms and soles. This is due to Yang Qi failing to circulate to the four extremities. He further stated: Cold and stiff hands and feet indicate solitary Yang without Yin, which is difficult to treat. If the abdominal veins are blue and tense, it indicates Wood overacting on Earth; immediately use Liujunzi Tang (Six Gentlemen Decoction) added with Pao Jiang (Processed Ginger), Rou Gui (Cinnamon Bark), Sheng Ma (Cimicifuga Rhizome), and Chai Hu (Bupleurum Root) to restore true Qi. If wind-pathogen lodges in the four extremities causing stiffness and cold, the etiology must be sought within the context of Wind Convulsion disorders.

Ren Shen (Ginseng Root), Bai Zhu (Atractylodes Macrocephala Rhizome), Fu Ling (Poria), Chen Pi (Citrus Reticulata Peel), Ban Xia (Pinellia Tuber), Zhi Gan Cao (Honey-fried Licorice Root).
