有物有声谓之呕，有物无声吐证名，无物有声为哕证，分别医治中病情。
【注】吐证有三∶曰呕，曰吐，曰哕。古人谓呕属阳明，有声有物，气血俱病也；吐
属太阳，有物无声，血病也；哕属少阳，有声无物，气病也。独李杲谓呕、吐、哕俱属
脾胃虚弱。洁古老人又从三焦以分气、积、寒之三因。然皆不外诸逆上冲也。治者能分虚
实，别寒热以治之，自无不曲中病情矣。

有实物排出且伴有声音的称为“呕”，有实物排出但无声响的称为“吐”，无实物排出仅有声音的称为“哕”，在临床治疗中需根据具体病情进行区分。
【注释】呕吐类病症主要有三种：即“呕”、“吐”、“哕”。古人认为，“呕”归属于阳明经，既有声音又有实物排出，说明气血均受病邪影响；“吐”归属于太阳经，只有实物排出而无声音，属于血分病变；“哕”归属于少阳经，只有声音而无实物排出，属于气分病变。唯独李杲（李东垣）认为“呕”、“吐”、“哕”均归属于脾胃虚弱所致。洁古老人（张元素）则进一步从三焦角度区分了气、积、寒这三种致病原因。然而，这些观点都不外乎各种气机逆乱上冲的情况。医生若能分辨虚实，辨别寒热来进行治疗，自然能准确地契合病情。
乳汁或食物摄入过量积聚在胃中，乳片无法消化而频繁呕吐，身体发热、面色发黄、腹部胀满，服用消乳丸和保和丸具有神奇功效。
【注释】伤乳吐，是因为乳汁或食物吃得过饱，停滞蓄积在胃中，导致脾胃运化功能不及，呕吐物中多含有未消化的乳片，就像容器盛满后溢出一样。其症状表现为身体发热、面色萎黄、肚腹膨胀。治疗宜采用消乳丸、保和丸。以化解滞留的乳汁，安抚胃部并调和中焦，同时节制乳汁和食物的摄入，病情自然会停止。

【注释】伤食吐，是因为小儿饮食没有节制，过量食用油腻、面食等食物，导致食物壅塞在中脘部位而形成。其症状表现为肚腹胀热、厌恶进食、口中有臭味、频繁呕吐酸粘之物、眼睑虚浮、身体出现潮热。治疗应以清胃和中为主。先用三棱丸止住呕吐，再用和胃汤化解积滞，病情就会逐渐痊愈。

There is a substance expelled accompanied by sound, which is termed "Ou" (vomiting with sound); there is a substance expelled without sound, which is termed "Tu" (spitting up/vomiting without sound); there is no substance expelled but only sound, which is termed "Yue" (hiccups/belching). Treatment must distinguish the specific condition.
[Note] There are three types of vomiting syndromes: namely "Ou", "Tu", and "Yue". The ancients stated that "Ou" belongs to the Yangming channel, presenting with both sound and substance, indicating that both Qi and Blood are diseased; "Tu" belongs to the Taiyang channel, presenting with substance but no sound, indicating a disease of the Blood aspect; "Yue" belongs to the Shaoyang channel, presenting with sound but no substance, indicating a disease of the Qi aspect. Only Li Gao (Li Dongyuan) asserted that "Ou", "Tu", and "Yue" all belong to Spleen-Stomach deficiency. Jiegou Laoren (Zhang Yuansu) further differentiated the three causes—Qi, Accumulation, and Cold—from the perspective of the Triple Burner. However, none of these exceed the concept of various rebellious upward rushing of Qi. If the practitioner can differentiate between Deficiency and Excess, and distinguish Cold from Heat in treatment, they will naturally hit the mark accurately regarding the condition.
