[Qian Yi] Xu Lei (Emaciation and debility) syndrome arises from disharmony of the Spleen and Stomach, inability to digest milk and food, leading to emaciated muscles. It may also result from after a severe illness, or following vomiting and diarrhea, where the Spleen and Stomach remain weak and fail to transform and transport grain qi (nutritive essence). In cold-type cases, there is frequent dysentery/diarrhea, with blue-white lips and mouth. In heat-type cases, there is high fever and slightly yellowish muscles; this is termed Cold-Heat Xu Lei. For cold type, Muxiang Wan (Aucklandia Pill) is the primary treatment; it should not be taken in summer, but if symptoms arise, take a small dose. For heat type, Huhuanglian Wan (Coptis Pill) is used; it should not be be taken in winter, but if symptoms arise, take a small dose. (Xu Lei is treated similarly to Gan Ji [Infantile Malnutrition]. The formulas for Muxiang Wan and Huhuanglian Wan are found under the Gan Ji section.)
[Tang Shi] Infantile Gan Ji (accumulation transforming into malnutrition), characterized by gradual sallow complexion and emaciation, a drum-like sound upon patting the back, and a spine protruding like a saw, results from accumulation generating heat that transforms into Gan. It is suitable to administer Lushui Wan (Aloe Pill) and Luxing Gao (Luxing Ointment/Pill).
Lushui Wan
Longdan Cao (Gentianae Radix), Huanglian (Coptidis Rhizoma), Wuyi (Pruni Semen) (peeled, first stir-fried until yellow, then stir-fried together with the previous two ingredients until red. Each 1 liang).
Grind the above into powder, add 1 fen of Lushui (Aloeswood), mix evenly, and form pills using mushy rice, sized like millet grains. Children aged three years should take 30 pills on an empty stomach, delivered with rice water.
Luxing Gao
Huangqi (Astragali Radix) (honey-fried), Huhuanglian (Coptidis Rhizoma), Digupi (Lycii Cortex), Chaihu (Bupleuri Radix) (each in equal proportions).
Grind the above into powder, form pills using refined honey, sized like quinoa seeds. Soak overnight in wine, leave exposed to dew overnight, clarify and remove the wine the next day, and take infused in mint decoction.
[Qian Yi] Julian Wan treats Gan emaciation; long-term use aids digestion, harmonizes qi, and promotes muscle growth.
Jupi (Citri Reticulatae Pericarpium) (1 liang), Huanglian (Coptidis Rhizoma) (soaked in rice wash water overnight, 1.5 liang).
Grind the above into fine powder. Separately grind 5 fen of Shexiang (Moschus), place seven pig gallbladders, divide the medicine into the gallbladders, boil in starch water. When nearly cooked, pierce slightly with a needle, until fully cooked. Mix with millet porridge to form pills sized like mung beans. Take 10 to 20-30 pills each time, delivered with rice water, adjusting dosage according to the child's condition, at any time. (Zhang Yuansu stated: Huanglian's bitter dryness can clear Spleen fire and promote muscle growth.)
Ersheng Wan treats infantile organ dysfunction, whether constipation or diarrhea, persisting without cure, accompanied by emaciation; suitable for regular use.
Huanglian (Coptidis Rhizoma) (remove stamens), Huangbai (Phellodendri Cortex) (remove rough bark. Each 1 liang).
Grind the above into fine powder, place inside a pig gallbladder, cook thoroughly in double-boiled water, form pills sized like mung beans. Take 20-30 pills each time, delivered with rice water, adjusting dosage according to the child's condition; frequent administration is permissible.
[Liu Wansu/Li Dongyuan context - Note: Text attributes to Jie [Li Dongyuan/Gujie]] Infantile Gan disease, with emaciated muscles and insufficient blood and qi, should be treated similarly to adult Lao Zhai (consumption/chronic wasting disease).
Based on Gujie's aforementioned discussion, regardless of Cold-Heat Xu Lei, combining Sizijunzi Tang (Four Gentlemen Decoction), Dihuang Wan (Rehmannia Pill) with the aforementioned medicines is considered appropriate.
[Shengji Jing] Another prescription treats infantile Shizhu (corpse transmission/wasting disease) and Lao Shou (wasting emaciation), or intermittent chills and fever. Use one turtle head, burn to ash, grind to powder, deliver 5 fenzhi (a traditional measure) with fresh drawn water; effect is immediate.
[Mingtang] Emaciation and failure to generate flesh/muscle: Moxibustion on Weishu (Stomach Shu, BL21) (one moxa cone).
[Tian Shi] Infantile Gan emaciation. Moxibustion three cones on the sharp bone below the chest, followed by three cones on the sharp bone at the lower end of the spine (coccyx tip).
For infantile Gan emaciation with rectal prolapse, emaciation, thirst, haggard appearance, and unresponsive to various prescriptions: Moxibustion three cones in the bony depression three cun above the coccyx tip.
For infantile body emaciation, Ben Tun (fleeing gas) with abdominal swelling, flaccid limbs, inability to raise shoulders and back: Moxibustion Qimen (LR14) acupoint, seven cones on each side.
[Worldly Physicians] If the mother's qi is insufficient, it leads to extreme emaciation of the infant's flesh.
