[Overview] This herb is also known as Xuanhusuo, Yuanhusuo, and Yuanhu. It is the tuber of Corydalis yanhusuo W.T.Wang, a plant of the Papaveraceae family. It is mainly produced in Zhejiang, Jiangsu, Anhui, and Hubei provinces. It is harvested in early summer when the stems and leaves wither, the tubers are dug up, the fibrous roots removed, washed clean, then boiled in boiling water until the white core just disappears, taken out, and dried.

[Properties] The taste is pungent and bitter; the nature is warm. It enters the Liver and Spleen meridians.

[Actions] Invigorates blood and dispels blood stasis; promotes the movement of qi and relieves pain.

[Applications] Used for various painful conditions caused by qi stagnation and blood stasis, especially common for heart and abdominal pain. For liver qi stagnation transforming into heat and disharmony between liver and stomach causing epigastric distension and pain extending to the hypochondrium, it is often combined with Chuanlianzi (Toosendan Fructus), as in Jinlingzi San. For cold-type epigastric pain, it is combined with Rougui (Cinnamomi Ramulus) and Gaoliangjiang (Alpiniae Officinarum Rhizoma). For epigastric pain due to middle jiao qi deficiency, it may be combined with Dangshen (Codonopsis Radix), Baizhu (Atractylodis Macrocephalae Rhizoma), and Baishao (Paeoniae Radix Alba). For chest impediment and heart pain due to heart blood stasis, it is often combined with Danshen (Salviae Miltiorrhizae Radix), Guizhi (Cinnamomi Ramulus), Xiebai (Allii Macrostemonis Bulbus), and Gualou (Trichosanthis Fructus). For hernia pain, it is commonly combined with Huixiang (Foeniculi Fructus) and Wuzhuyu (Evodiae Fructus). For hernia with testicular swelling and hardness and pain radiating to the umbilical region, it is often combined with Juhé (Citri Reticulatae Endocarpium), Taoren (Persicae Semen), Kunbu (Laminariae Thallus), and Haizao (Sargassum). For dysmenorrhea, irregular menstruation, and postpartum blood stasis pain due to qi stagnation and blood stasis, it is combined with Danggui (Angelicae Sinensis Radix), Xiangfu (Cyperi Rhizoma), and Chuanxiong (Chuanxiong Rhizoma). This herb is also used for wind-damp bi syndrome and lumbar and leg pain, often combined with Qin Jiao (Gentianae Macrophyllae Radix), Guizhi (Cinnamomi Ramulus), and Weilingxian (Clematidis Radix et Rhizoma). For chronic bi syndrome with liver and kidney deficiency, it is combined with Niuxi (Achyranthis Bidentatae Radix), Danggui (Angelicae Sinensis Radix), and Buguzhi (Psoraleae Fructus). For traumatic injuries, it can be used alone as a powder mixed with wine or combined with Taoren (Persicae Semen) and Honghua (Carthami Flos).

[Dosage and Administration] Internal use: decoction, 3–9 g; powder, 1.5–3 g. Raw use and wine-fried processing enhance blood-activating and stasis-dispelling effects; vinegar-frying enhances liver entry and analgesic effects.

[Modern Research]
1. Chemical constituents: The tuber contains dextrorotatory protopine (Yanhusuo A), protopine (Yanhusuo B), levorotatory and racemic tetrahydropalmatine, levorotatory tetrahydrocolumbamine, dextrorotatory corydaline, α-allocryptopine, racemic tetrahydropalmatine (Yanhusuo C), dextrorotatory corydaline, berberine, dehydrocorydaline, and yanhuscoside.
2. Pharmacological effects: Yanhusuo powder has analgesic effects, with active ingredients being its alkaloids; no addiction was found. Yanhusuo C has significant sedative, hypnotic, and tranquilizing effects; it can inhibit pentylenetetrazol-induced convulsions and has mild central antiemetic and hypothermic effects. Alcohol extracts of Yanhusuo significantly dilate animal coronary arteries and increase coronary blood flow. Dehydrocorydaline protects against experimental ulcers in rats caused by starvation, pyloric ligation, or drugs, reducing gastric juice secretion, acid, and pepsin; this effect may be mediated via the central nervous system-pituitary-adrenal axis.
3. Clinical reports: 1) Arrhythmia: Oral Yanhusuo powder (pills) 5–10 g each time, three times daily. Treated 48 cases of arrhythmia for 4–8 weeks; total effective rate about 84%. [Beijing Medicine, 1984, 6(3):176] 2) Acute myocardial infarction: Oral dehydrocorydaline 5–10 mg, three times daily. Observed 74 cases of acute myocardial infarction. After 4–8 weeks, arrhythmia incidence was lower than Western medicine control group; no side effects observed. [Tianjin Traditional Chinese Medicine, 1989, (4):3] 3) Chronic superficial gastritis: Yanhusuo 10 g, Hedyotis Diffusa (Baihuasheshecao) 50 g, boiled with 250–300 ml water for 30 minutes. Decoction taken twice daily, divided into three doses before meals, for 20 days per course. Treated 82 cases: 65 cured, 14 improved, 3 ineffective; total effective rate 96.3%. [Hunan Journal of Traditional Chinese Medicine, 1992, 8(2):33] 4) Acute and chronic sprains: Used Yanhumu Jin San (vinegar-processed Yanhusuo, Guangmuxiang, Yujin in equal parts, finely powdered), 15 g each time with warm water, three times daily.
