Chuanxiong
Overview
Chuanxiong (川芎) refers to a perennial herb belonging to the Apiaceae family, or to the dried herbal medicine made from its rhizome. The name originates from Sichuan Province (四川) in China, and it has been used in the traditional medicine of Korea, China, and Japan as a representative medicinal material for activating blood (活血), moving qi (行氣), dispelling wind (祛風), and relieving pain (鎭痛). It is widely applied to various symptoms accompanied by blood circulation disorders and pain, such as headache, dysmenorrhea, blood stasis (瘀血), and chest impediment (胸痺), and is included as a key constituent in many prescriptions, including Siwutang (四物湯).
Main Content
Botanical Classification and Morphology
Chuanxiong is an umbellifer of the family Apiaceae, with the scientific name Ligusticum chuanxiong (synonym Cnidium officinale). It grows to 30–60 cm in height and produces white umbellate inflorescences in autumn. The medicinal part is the underground rhizome, which is irregularly lump-shaped, brown on the surface, and has a distinctive strong aroma and slightly pungent taste. Harvesting usually occurs in spring and autumn; after digging, the soil is shaken off and the rhizome is dried in sunlight or hot air for distribution.
Major Constituents
The representative active constituents of Chuanxiong are the phthalide compounds ligustilide and butylidenephthalide, and the phenolic compound ferulic acid. It also contains tetramethylpyrazine, senecionine-type alkaloids, various saponins, and essential oil components. Ligustilide is known as the main component of Chuanxiong's distinctive aroma and the key substance responsible for its vasodilatory action.
Pharmacological Actions
In modern pharmacological research, Chuanxiong extract has been reported to have the following actions. First, vasodilation through relaxation of vascular smooth muscle and improvement of peripheral blood flow. Second, inhibition of platelet aggregation and improvement of microcirculation, thereby suppressing thrombus formation. Third, analgesic and antispasmodic actions on the central nervous system, involved in alleviating headache and neuropathic pain. Fourth, antioxidant and anti-inflammatory actions; fifth, neuroprotective effects against ischemic brain injury, etc., have been confirmed at the experimental level.
Use in Traditional Medicine
In Korean medicine, Chuanxiong is called the "qi medicine among blood medicines" and is classified as a medicinal material that moves blood while helping the circulation of qi. Representative prescriptions include Siwutang, Chuanxiong Chatiao San (川芎茶調散), Xionggui Tang (芎歸湯), and Taohong Siwu Tang (桃紅四物湯), and it is used for migraine and tension headache, dysmenorrhea and amenorrhea, postpartum blood-stasis abdominal pain, and chest pain accompanied by coronary artery disease. In China it is called "chuanxiong," and in Korea it is also called "cheon-gung" or "gung-gungi."
Cultivation and Distribution
In Korea, it is cultivated in highland areas around Gangwon Province and North Gyeongsang Province, while Sichuan Province and Yunnan Province are considered the largest production areas in China. Recently, as standards for managing residual pesticides and heavy metals have been strengthened, the GAP (Good Agricultural Practices) certification system and distribution traceability systems have been introduced. In the identification of herbal medicines, quality is evaluated based on morphology, aroma, and constituent content (ligustilide and ferulic acid).
Precautions and Side Effects
Chuanxiong may increase bleeding tendency, so caution is needed in patients with hemophilia, thrombocytopenia, and in patients before and after surgery. When used concomitantly with anticoagulants or antiplatelet agents such as warfarin and aspirin, the risk of bleeding may increase, and in pregnant women its use is in principle restricted due to the risk of miscarriage. In addition, overdose may cause gastrointestinal disorders, dizziness, skin rash, etc.
Recent Trends
In 2024–2025, research on neurological and vascular diseases using the active constituents of Chuanxiong is active. Many studies have reported that ligustilide is involved in blood-brain barrier protection and inhibition of neuroinflammation in ischemic stroke models, and its clinical potential for vascular dementia and migraine prevention is also being discussed. In addition, as attempts to use Chuanxiong extract as a material for functional foods and cosmetics increase, research on developing standardized extracts and establishing quality markers is underway. In Korea, along with strengthened quality control of herbal medicines, AI and machine-learning-based constituent profiling techniques have been introduced, improving the accuracy of origin discrimination and adulteration detection. Furthermore, as pharmacovigilance data on cases of concomitant use of anticoagulants that interact with Chuanxiong accumulate, establishing safe dosage standards in clinical practice is emerging as a major task.
