The patient experiences distension and fullness in the heart and diaphragm, with Qi counterflow rising in the chest. Food is vomited immediately upon ingestion, but relief is felt after vomiting; this condition is named Qi Oup (Qi Vomiting). The Stomach belongs to the Foot Yangming channel; its Qi should descend and harmonize with Ying Qi (Nutritive Qi). Now, following the counterflow of Qi, it knots at the gastric opening, thus generating vomiting.

For treating Qi Oup accompanied by chest fullness, inability to accept food, vomiting of saliva and froth, and headache:
Evodiae Fructus (Wu Zhu Yu) (washed several times with hot water, 5 liang), Ren Shen (Ginseng Radix et Rhizoma) (3 liang).
Grind the above into a coarse powder. For each dose, take 4 qian, add 1.5 zhan of water, 5 slices of fresh ginger, and 3 jujubes. Decoct until reduced to 70%, strain, and take at any time.

For treating deficiency-fullness below the heart, inability to ingest food, frequent vomiting, shortness of breath; or when recovery from a severe illness is improper, leading to a lack of nourishment for Stomach Qi, resulting in gradual emaciation and weakness:
Agastegis Herba (Huo Xiang), Ren Shen (Ginseng Radix et Rhizoma), Cinnamomi Cortex (Gui Xin), Platycodi Radix (Jie Geng), Aquilariae Lignum Resinatum (Mu Xiang), Atractylodis Macrocephalae Rhizoma (Bai Zhu) (each 0.5 liang), Poria (Fu Ling) (0.5 liang), Loquat Leaf (Pi Pa Ye) (10 leaves, remove hairs), Pinelliae Rhizoma Preparatum (Ban Xia) (1 liang, washed with hot water and processed with fresh ginger juice).
Grind the above into a coarse powder. For each dose, take 5 qian, add 2 zhan of water, and 1 fen of stir-fried shredded ginger. Decoct until reduced to 70%, strain, and take before meals.

The patient feels heat over the back, spasmodic pain in the elbows and arms, interrupted breathing, oppression and stuffiness in the diaphragm. After eating, food is first vomited out and then excreted; this condition is named Lou Qi (Leaking Qi). This is caused by Wind injuring the Upper Jiao, causing the couli (pores) to open. The Qi of the Upper Jiao is fierce, rapid, and slippery; encountering the open couli, it escapes outward. The meridian Qi loses its proper path, and pathogenic factors settle internally, hence these symptoms.

For treating latent Heat in the Upper Jiao causing abdominal fullness, anorexia, sweating before food is digested in the Stomach, and heat over the entire back; or when food is ingested, first vomited out and then excreted, named Lou Qi (Leaking Qi):
Ophiopogonis Radix (Mai Men Dong) (remove the heart), Raw Reed Rhizome (Sheng Lu Gen), Bamboo Shavings (Zhu Ru), Atractylodis Macrocephalae Rhizoma (Bai Zhu) (each 5 liang), Glycyrrhizae Radix et Rhizoma Preparata (Zhi Gan Cao), Poria (Fu Ling) (each 2 liang), Citri Reticulatae Pericarpium (Ju Pi), Ren Shen (Ginseng Radix et Rhizoma), Polygonati Rhizoma (Wei Rui) (each 3 liang).
Grind the above into a coarse powder. For each dose, take 4 qian, add 1.5 zhan of water, 5 slices of fresh ginger, and a pinch of aged rice. Decoct until reduced to 70%, strain, and take while hot.

The patient suffers from Excess-Heat in the Lower Jiao, with obstruction of urination and defecation, counterflow Qi that cannot be sustained, and uncontrollable vomiting and regurgitation; this condition is named Zou Bu (Walking Nourishment/Feeding). This arises from Qi in the Lower Jiao originating from the lower opening of the Stomach, diverting into the ileum, and pouring into the Bladder. It works together with the Stomach to transmit dregs downward into the Large Intestine, causing obstruction of urination and defecation. Thus, it is known to be caused by Excess-Heat in the Lower Jiao.
