吐症有五。一曰 ，乳哺过多，口角流出，满而溢也，勿与乳，则以陈米煮粥与食，勿药
可也。二曰逆（上升为逆），气贵下降，消食顺气为主。三曰吐，为顿出有物无声，以苍术、藿
香、二陈汤等。四曰呕，为渐出有物有声，亦用上方，五曰哕，即干呕也，有声无物，乃属火，
最为恶候。生姜为呕家圣药，若儿伤食为多，不可与乳。乳味甘，令中满，且动舌筋，起胃火。初
生小儿便吐，由拭口中秽血不尽，或食胞浆，故令吐多。用甘草、黄连汁或吾家小黑丸，不止服正
胃散。伤食吐、冷吐可服温胃调
气汤。
温胃调气汤
苍术（正胃气） 浓朴（泄中气） 半夏 香附（正气） 山楂 神曲 麦芽 藿香（正
气） 干姜 茯苓
服此不止，若见是冷，可加木香、丁香、浓朴，次第加之。若是伤食，以枳实、青皮、槟榔
次第加之。用前药又不止，是胃气因吐而虚，面青白，唇淡，精神少，可加人参。此症必眼眶
陷下，方可用参，若不用参，恐虚极生风，传为慢惊。
暑月有热吐者，因冒暑或伤热食，致热气入胃，吐也。食与气相搏而吐也，其症眼眶陷，
唇燥，舌有刺，大便焦黄，射出如臭鸭蛋腥气，用水泼地令儿卧上，用黄瓜同卧。宜服清热之
剂，如后吐泻论中清胃止渴汤可加减用之。初生小儿吐，余家小黑丸最妙。
There are five types of vomiting syndromes. The first is spilling milk (spilling milk), caused by excessive feeding, where milk flows from the corners of the mouth due to stomach fullness; in this case, do not feed milk again, but provide porridge made from aged rice, and medication is unnecessary. The second is Qi reversal (Qi rising is termed reversal); Qi should descend, so treatment focuses on digesting food and smoothing Qi flow. The third is "Tu" (vomiting without sound), characterized by sudden expulsion of contents without sound; treat with Cangzhu (Atractylodis Rhizoma), Huoxiang (Agastachis Herba), Erchen Tang (Two-Cured Decoction), etc. The fourth is "Ou" (vomiting with sound), characterized by gradual expulsion with sound; the above prescriptions may also be used. The fifth is "Yue" (hiccup or dry heaving), which is dry heaving with sound but no substance expelled; this belongs to Fire syndrome and is a most ominous sign. Shengjiang (Zingiberis Rhizoma Recens) is the holy medicine for vomiting. If infants vomit due to food stagnation, breast milk should not be given. Milk is sweet in flavor, causing middle Jiao fullness, stimulating the tongue tendons, and stirring up Stomach Fire. Newborns who vomit immediately after birth do so because residual blood in the mouth was not wiped clean, or they ingested amniotic fluid, leading to frequent vomiting. Use Gancao (Glycyrrhizae Radix et Rhizoma) and Huanglian (Coptidis Rhizoma) juice, or our family's Xiaohei Wan (Little Black Pill); if ineffective, administer Zhengwei San (Stomach-Regulating Powder). Food-stagnation vomiting and cold-type vomiting can be treated with Wenwei Tiaoqi Tang (Warming Stomach and Regulating Qi Decoction).
Wenwei Tiaoqi Tang (Warming Stomach and Regulating Qi Decoction)
Cangzhu (Atractylodis Rhizoma) [regulates Stomach Qi] Houpo (Magnoliae Officinalis Cortex) [drains Middle Jiao Qi] Banxia (Pinelliae Rhizoma) Xiangfu (Cyperi Rhizoma) [regulates Qi] Shanzha (Crataegi Fructus) Shenqu (Massa Medicata Fermentata) Maiya (Hordei Fructus Germinatus) Huoxiang (Agastachis Herba) [regulates Qi] Ganjiang (Zingiberis Rhizoma) Fuling (Poria)
If vomiting persists after taking this formula, and the pattern is identified as Cold, add Muxiang (Aucklandiae Radix), Dingxiang (Caryophylli Flos), and Houpo sequentially. If it is due to food stagnation, add Zhishi (Aurantii Fructus Immaturus), Qingpi (Citri Reticulatae Pericarpium Rubrum), and Binglang (Arecae Semen) sequentially. If previous medications fail to stop vomiting, it indicates that Stomach Qi has become deficient due to vomiting, presenting with bluish-white complexion, pale lips, and lethargy; in this case, add Renshen (Ginseng Radix et Rhizoma). This condition requires sunken eye sockets before Ginseng can be used; otherwise, extreme deficiency may generate Wind, transmitting into Slow Convulsion (Man Jing Feng).
In summer months, there is Heat-type vomiting, caused by exposure to Summerheat or consuming hot foods, leading to Heat entering the Stomach. Food and Qi struggle against each other, causing vomiting. Symptoms include sunken eye sockets, dry lips, prickly sensation on the tongue, scorched yellow stool, and discharge with a foul odor resembling rotten duck eggs. Let the infant lie on the ground sprinkled with water, and place a cucumber alongside them. It is appropriate to administer Heat-clearing agents, such as Qingwei Zhike Tang (Clearing Stomach and Quenching Thirst Decoction) mentioned in the subsequent section on Vomiting and Diarrhea, modified as needed. For newborn vomiting, our family's Xiaohei Wan (Little Black Pill) is most effective.
