呕吐虽本于胃，然所因亦多端，故有寒热饮食血气之不同，皆使人呕吐。据论云∶寒气
在上，忧气在下，二气并争，但出不入。此亦一涂，未为尽论。且如气属内因，则有七种不
同；寒涉外因，则六淫分异，皆作逆，但郁于胃则致呕，岂拘于忧气而已。况有宿食不消，
中满溢出，五饮聚结，随气番吐，痼冷积热，及瘀血凝闭，更有三焦漏气走哺，吐利泄血，
皆有此证，不可不详辨也。
病者胃中寒，心下淡淡，四肢厥冷，食既呕吐，名曰寒呕。或因伤食多，致伤胃气；或
因病曾经汗下，致胃气虚冷之所为也。
治寒呕脉弱，小便复利，身有微热。见厥者难治。

Although vomiting originates in the Stomach, its causes are manifold. Thus, there are differences due to Cold, Heat, food, blood, and Qi, all of which can cause vomiting. According to some theories: "Cold Qi is above, Sorrow Qi is below; when these two Qi contend, only ejection occurs without intake." This is but one perspective and not a comprehensive discussion. Moreover, Qi disorders belong to internal causes and have seven distinct types; Cold pathogens involve external causes, differentiated by the Six Excesses (Wind, Cold, Summerheat, Dampness, Dryness, Fire), all causing rebellious Qi. If they stagnate in the Stomach, vomiting ensues; it is not limited merely to Sorrow Qi. Furthermore, there is undigested retained food causing middle-jiao fullness and overflow; accumulation of the Five Drinks (Phlegm, Yin, Water, Dampness, Retained Fluid) leading to vomiting with Qi rebellion; entrenched Cold or accumulated Heat; and blood stasis causing obstruction. Additionally, there is leakage of Qi from the Triple Burner resulting in immediate vomiting after eating, vomiting with diarrhea, and bleeding from stool. All these present with similar symptoms and must be carefully differentiated.
When the patient has Cold in the Stomach, palpitations in the epigastrium (dandan), cold limbs, and vomiting immediately after eating, it is named Cold Vomiting. This may occur due to excessive food injury damaging Stomach Qi, or as a result of previous sweating or purging therapies during illness, leading to deficiency and Cold of the Stomach Qi.
For treating Cold Vomiting with a weak pulse, frequent urination, and slight fever on the body: if cold limbs are present, it is difficult to treat.
