有物有声谓之呕，有物无声吐证名，无物有声谓哕证，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。

吐证门
有实物且有声音的称为“呕”，有实物但无声音的称为“吐”，无实物但有声音的称为“哕”，治疗时需根据病情分别处理。
[注]
呕吐类病症有三种，即“呕”、“吐”、“哕”。
古人认为“呕”属于阳明病（阳明经受邪所致的病证），特点是既有声音又有实物，是气血均受病的表现；
“吐”属于太阳病（太阳经受邪所致的病证），特点是有实物而无声音，是血分受病的表现；
“哕”属于少阳病（少阳经受邪所致的病证），特点是有声音而无实物，是气分受病的表现。
唯独李杲（金元四大家之一）认为“呕、吐、哕”都归属于胃气虚弱。
洁古老人（张元素）又从三焦（上焦、中焦、下焦）的角度区分气滞、积食、寒邪这三种病因，然而这些观点都不外乎各种气逆上冲的病机。
治疗者若能辨别虚实、区分寒热来进行治疗，自然能准确地契合病情。

There is a distinction between vomiting, spitting up, and hiccups based on the presence of sound and matter: "Ou" (vomiting with sound and matter), "Tu" (spitting up with matter but no sound), and "Yue" (hiccups with sound but no matter). Treatment must be tailored to the specific condition.
[Note]
There are three types of regurgitation disorders: Ou (vomiting), Tu (spitting up), and Yue (hiccups).
Ancient texts state that Ou belongs to Yangming disease (diseases affecting the Yangming meridians), characterized by both sound and expelled matter, indicating pathology in both Qi and Blood.
Tu belongs to Taiyang disease (diseases affecting the Taiyang meridians), characterized by expelled matter without sound, indicating pathology primarily in Blood.
Yue belongs to Shaoyang disease (diseases affecting the Shaoyang meridians), characterized by sound without expelled matter, indicating pathology primarily in Qi.
However, Li Gao (a prominent physician of the Jin-Yuan period) argued that Ou, Tu, and Yue all stem from Stomach Qi deficiency.
Jiegu Laoren (Zhang Yuansu) differentiated these conditions based on the Sanjiao (Triple Burner) regarding causes such as Qi stagnation, food accumulation, and Cold. Nevertheless, all these views revolve around the mechanism of rebellious Qi rushing upward.
If practitioners can distinguish between Deficiency and Excess, and Cold and Heat, their treatment will naturally align accurately with the patient's condition.

Excessive milk intake accumulates in the Stomach; undigested milk curds are frequently vomited. Symptoms include fever, sallow complexion, and abdominal distension. Xiaoru Wan (Milk-Digesting Pills) and Baohe Wan (Preserve Harmony Pills) are highly effective.
[Note]
Shangru syndrome (milk injury) occurs when excessive milk intake stagnates in the Stomach, overwhelming its transportation and transformation functions.
The vomitus contains many milk curds, resembling overflow from an overfilled container.
Symptoms include fever, sallow complexion, vomiting accompanied by abdominal distension.
Treatment should focus on using Xiaoru Wan and Baohe Wan to resolve retained milk, stabilize the Stomach, harmonize the Middle Jiao, and regulate milk intake, which will naturally stop the vomiting.

Symptoms include abdominal distension and heat, aversion to food, foul breath, frequent vomiting of sour sticky fluid, puffy eyelids, and tidal fever.
