The pulse is wiry and slippery. The pulses at both hands may be floating or wiry, or floating and slippery, or deep and slow, or tight and surging, or surging and rapid, or deep and slow. There is cold-fluid retention in the chest. If the pulse is surging and rapid, it indicates phlegm-heat lodged in the chest and diaphragm. Frequent regurgitation of sour fluid occurs, which may develop into Fanwei (a condition characterized by vomiting undigested food eaten hours earlier).
Sourness is the flavor associated with Liver Wood. It arises when excessive Fire controls Metal (Lung), preventing Metal from properly restraining Wood (Liver), causing Liver Wood to become hyperactive, thus producing sourness. If food and drink are too hot, sourness is more likely to occur. Some claim that vomiting acid is caused by Cold; this is incorrect. In reality, Damp-Heat lingers above the stomach opening. When food enters the stomach, it is constrained by Damp-Heat, failing to digest, thereby causing Tun Suan (acid regurgitation with a sensation of heartburn). Just as grains and meats covered in a vessel easily turn sour when damp, so too does food in the stomach. One must use Evodiae Fructus (Wuzhuyu) to follow its nature and subdue the Liver; this is the correct method.
Another discussion on Tun Suan and Zaocha (a sensation of hunger with discomfort but no desire to eat), where sour fluid pierces the heart: this is due to Phlegm-Fire constraining Qi. Qingyu Erchen Tang (Clearing Stagnation and Resolving Phlegm Decoction) is appropriate: Chenpi (Tangerine Peel), Banxia (Pinellia Rhizome, stir-fried with ginger juice), Fuling (Poria), Xiangfu (Cyperus Rhizome), Huanglian (Coptis Rhizome, stir-fried with ginger juice), Zhizi (Gardenia Fruit, stir-fried, each 1 qian), Cangzhu (Atractylodes Rhizome, soaked in rice water), Chuanxiong (Ligusticum Rhizome), Zhishi (Immature Bitter Orange, stir-fried, each 8 fen), Shenqu (Medicated Leaven, stir-fried, 3 qian), Baishao (White Peony Root, stir-fried, 7 fen), Gancao (Licorice Root, 2 fen). These herbs are cut into pieces for one dose, decocted with fresh ginger, and taken warm.
Another discussion on vomiting acid due to emotional stagnation: Zhulian Wan (Evodia and Coptis Pill) is used. Cangzhu (Atractylodes Rhizome, soaked in rice water, 1 liang), Chenpi (Tangerine Peel, 1 liang), Banxia (Pinellia Rhizome, stir-fried with ginger juice, 1 liang), Baifuling (Poria, peeled, 1 liang), Huanglian (Coptis Rhizome, 1.5 liang, stir-fried with ginger juice, double dose in summer), Wuzhuyu (Evodia Fruit, stir-fried, 1 liang, double dose in winter). These are ground into fine powder, mixed with steamed bread paste to form pills the size of mung beans. Take 30–50 pills after meals, washed down with plain boiled water.
Another discussion on belching, Tun Suan, and Zaocha accompanied by phlegm, heat, Qi stagnation, and food retention, with a feeling of fullness in the chest and diaphragm and indigestion: Xiangkou Hezhong Wan (Fragrant Cardamom Harmonizing the Middle Pill) is used. Baizhu (Atractylodes Macrocephala Rhizome, de-stemmed and stir-fried), Shanzha (Hawthorn Fruit Flesh), Lianqiao (Forsythia Fruit, each 4 liang), Laifuzi (Radish Seed, stir-fried, 5 qian), Baifuling (Poria, peeled), Zhishi (Immature Bitter Orange, de-pithed and stir-fried with bran), Chenpi (Tangerine Peel, de-white), Banxia (Pinellia Rhizome, stir-fried with ginger juice), Shenqu (Medicated Leaven, stir-fried, each 2 liang), Ganshengjiang (Dried Ginger, 1 liang), Baidoukou (White Cardamom Seed, stir-fried, 5 qian), Muxiang (Aucklandia Root, 5 qian). These are ground into fine powder, mixed with Medicated Leaven paste to form pills the size of paulownia seeds. Take 100 pills after meals, washed down with plain boiled water.
Another discussion on women experiencing sourness in the heart: this is due to phlegm-fluid accumulation between the spleen and stomach, causing frequent sour sensations in the heart region or vomiting of clear fluid. Wu Zhu Yu Wan (Evodia Pill) is used. Dayamai (Hordeum Vulgare Sprout, stir-fried, 5 qian), Rougui (Cinnamon Bark, 5 qian), Wuyu (Evodia Fruit, 1 liang, washed with salt water), Cangzhu (Atractylodes Rhizome, soaked in rice water, 1 liang), Chenpi (Tangerine Peel, de-white, 5 qian), Shenqu (Medicated Leaven, stir-fried, 5 qian). These are ground into fine powder, mixed with thin porridge paste to form pills the size of paulownia seeds. Take 50–60 pills, washed down with rice drink.
Another discussion on sourness in the heart region, where sour Qi rushes upward like strong vinegar, unbearable in intensity: Use 1 he of Evodia Fruit, add 1 zhang of water, decoct until 0.7 zhang remains, and take in one dose. Even if the liquid is strong, it must be forced down. There was a case where a patient felt their heart as if pierced; this formula produced immediate results.
Another treatment for vomiting clear fluid: Cangzhu (Atractylodes Rhizome, 2 qian, stir-fried with wall soil), Baizhu (Atractylodes Macrocephala Rhizome, 1.5 qian, de-stemmed and stir-fried), Chenpi (Tangerine Peel, 1.5 qian), Baifuling (Poria, 3 qian), Huashi (Talcum, stir-fried, 3 qian). Decoct in water and take.
A scholar who preferred extremely hot food and drink throughout the four seasons sometimes experienced Tun Suan and belching of putrid smells, loose stools, and damp, itchy spaces between the toes. This was due to deficiency-cold of the Spleen Qi sinking downward. Liujunzi Tang (Six Gentlemen Decoction) was used, added with fresh ginger and cinnamon, resulting in recovery. However, slight dietary indiscretion caused the diseases to recur. Using the previous prescription with the addition of approximately 1 qian of Fuzi (Prepared Aconite Root) for several doses prevented further recurrence.
A woman with Tun Suan, belching of putrid smells, vomiting of phlegm-saliva, and a purely white complexion was treated by others with Erchen Tang (Two-Cured Decoction), Huanglian (Coptis Rhizome), Zhishi (Immature Bitter Orange), etc., leading to fever, thirst, and abdominal distension. I stated: This is damage to the Spleen and Stomach, eventually transmitting to Cold. The patient did not believe me and continued treating it as Heat, resulting in limb swelling resembling Guzhang (Gu Distension). I treated her with Liujunzi Tang added with Fuzi (Prepared Aconite Root) and Muxiang (Aucklandia Root). Her Stomach Qi gradually revived, and her diet slowly increased, returning the deficient fire to its source. Subsequently, she took Buzhong Yiqi Tang (Tonify the Middle and Augment the Qi Decoction) added with Paojiang (Roasted Ginger), Muxiang (Aucklandia Root), Fuling (Poria), and Banxia (Pinellia Rhizome), achieving complete recovery.
Another treatment for vomiting sour fluid after eating: Ganjiang (Dried Ginger) and Wuzhuyu (Evodia Fruit), each 2 liang, ground into powder. Take one fangcun chi (square-inch spoonful) per dose, mixed with wine, twice daily. For patients with Cold Stomach, immediate effects are seen upon administration.
