久病胃虚，闻谷气而呕者，此方主之。

呕吐，腹痛者，此方主之。
呕吐而痛即止者为火，呕吐而痛不止者为寒。然寒则收引，胡然能吐？师曰∶寒胜格阳
，故令吐也。治寒以热，故用丁香、干姜之温。吐多损气，故用人参、白术、甘草之补。

伤寒正汗后，余热留于阳明、少阳，必令作呕，此方主之。
阳明，胃也。少阳，胆也。有辨焉，口渴者热在胃，口苦者热在胆也。兼而有之，则二

人参、白术、茯苓、甘草（各二钱），半夏、陈皮（各一钱）。
久病导致胃气虚弱，闻到食物气味就呕吐的，用此方主治。
胃是水谷汇聚的大海，也是管理仓储的官职，所以胃气强盛则食欲好，胃气虚弱则闻到食物气味就会呕吐。《内经》说：“能进食者昌，不能进食者亡。”怎么能不急于治疗呢？因此用人参、白术、茯苓、甘草，药性甘温，可以补益胃气；陈皮、半夏，药性辛散通利，可以止呕。
人参、白术（炒）、甘草（炙）、丁香、干姜（炒）。
呕吐且伴有腹痛的，用此方主治。
呕吐后疼痛随即停止的是火证，呕吐而疼痛不止的是寒证。然而寒邪具有收引特性，为何会导致呕吐？老师说：“寒邪过盛格拒阳气，从而导致呕吐。”治疗寒证用热药，所以使用丁香、干姜的温热之性。呕吐过多损伤正气，所以使用人参、白术、甘草来补益。
葛根（三钱）、半夏（制）、竹茹（各二钱）、甘草（一钱）。
伤寒病经过正确发汗后，余热残留于阳明经、少阳经，必然导致呕吐，用此方主治。
阳明经对应胃，少阳经对应胆。二者有区别：口渴说明热在胃，口苦说明热在胆。如果两者兼有，则两条经络都有余热滞留。这个方子中，葛根清胃热，竹茹清胆热，半夏降逆止呕，甘草调和阳气。
雄黄、明矾、苦瓜蒂（炒，各五分）。
共研为细末，用酒送服。
呕吐且流口水，脉象平和的，是寄生虫病的证候。用此方催吐治疗。
虫体活动则流口水，胃痒则引起呕吐，脉象平和是指获得像健康人一样的无病脉象，不快不慢，无寒无热的表现。雄黄药性猛烈，明矾味苦涩，都是杀虫的药物。辅以善于涌吐的瓜蒂，则虫子立刻被吐出。又说：“体质实盛且能耐受催吐的，以此方为主；体质虚弱不能耐受催吐的，适宜用伤寒门中的乌梅丸。”

For vomiting triggered by the smell of food due to stomach deficiency resulting from prolonged illness, this formula is indicated.
The Stomach is the sea of water and grain, and the official responsible for storage; thus, a strong Stomach leads to good appetite, while a weak Stomach causes vomiting upon smelling food. The Classics state: "Those who can digest food prosper; those who cannot lose food perish." How can one fail to treat this urgently? Therefore, Ren Shen, Bai Zhu, Fu Ling, and Gan Cao have sweet and warm properties that tonify the Stomach. Chen Pi and Ban Xia have pungent and penetrating properties that resolve vomiting.

For vomiting accompanied by abdominal pain, this formula is indicated.
Vomiting followed by immediate cessation of pain indicates Heat syndrome; vomiting with persistent pain indicates Cold syndrome. Although Cold has a contracting nature, why does it cause vomiting? The Master said: "Excessive Cold repels Yang Qi, thereby causing vomiting." To treat Cold with Heat, warming agents such as Ding Xiang and Gan Jiang are used. Since excessive vomiting damages Qi, tonics such as Ren Shen, Bai Zhu, and Gan Cao are employed.

After proper sweating in Taiyang Cold Damage disease, if residual heat remains in the Yangming and Shaoyang channels, inevitably causing vomiting, this formula is indicated.
Yangming corresponds to the Stomach, and Shaoyang corresponds to the Gallbladder. There is a distinction: thirst indicates Heat in the Stomach, while bitter taste indicates Heat in the Gallbladder. If both are present, residual heat exists in both channels. In this formula, Ge Gen clears Stomach Heat, Zhu Ru clears Gallbladder Heat, Ban Xia descends rebellious Qi, and Gan Cao harmonizes Yang Qi.
Xiong Huang (Realgar), Ming Fan (Alumen), Gua Lou Di (Momordicae Fructus) (stir-fried, each 5 fen).
Grind into powder and take with wine.
For vomiting with salivation and a normal pulse, indicating a parasitic condition, this formula is used to induce vomiting.
Parasite movement causes salivation, and stomach itching causes vomiting. A normal pulse refers to the pulse of a healthy person, neither slow nor rapid, without signs of Cold or Heat. Xiong Huang is potent, and Ming Fan is bitter and astringent; both are vermifuges. Assisted by Gua Lou Di's ability to induce emesis, the parasites will be expelled immediately. It is also stated: For excess conditions where the patient can tolerate emesis, this formula is primary; for deficient conditions where emesis is not tolerated, Wumei Wan (Mume Pill) from the Cold Damage section is appropriate.
