Angelica gigas

Angelica gigas, known in Korea as “gyeonggok,” has a long history of use in East Asian traditional medicine. In Korean folk practice, the dried root is boiled into a decoction to treat menstrual cramps, dysmenorrhea, and abdominal pain; the same root is also brewed as a mild tea to relieve coughs and sore throats (Korean Pharmacopoeia, 2015). Among the Japanese Kampo practitioners, a powdered form of the root is mixed with water to make a decoction that is prescribed for chronic fatigue and digestive discomfort (Kampo Handbook, 2018). In Chinese herbal collections, Angelica gigas is listed as a variant of Angelica sinensis and is used in decoctions for anemia and to promote blood circulation, especially in the “Shen Qi Wan” formula (Chinese Pharmacopoeia, 2020). These preparations are typically made by simmering 10–15 g of dried root in 1 L of water for 30–45 minutes, then straining the liquid for consumption.

A simple, safe tea can be prepared at home with 5 g of dried Angelica gigas root and 200 ml of boiling water. Let the mixture steep for 10 minutes, then strain and drink warm. This mild infusion is suitable for adults, but pregnant women should avoid large doses because the root contains coumarins that may have uterine stimulant effects. As with any herbal product, it is wise to consult a qualified practitioner before using it regularly, especially if you are taking anticoagulant medications.

The therapeutic effects of Angelica gigas are largely attributed to its rich profile of coumarins and furanocoumarins, including imperatorin, isoimperatorin, and osthole, which have been shown to possess anti‑inflammatory, antioxidant, and vasodilatory properties. Polysaccharides extracted from the root also contribute to its immunomodulatory activity, while volatile oils such as angeloyl and furanocoumarin derivatives provide antimicrobial benefits. These constituents have been isolated and quantified in peer‑reviewed phytochemical studies, providing a clear biochemical basis for the plant’s traditional uses.

Modern research continues to explore Angelica gigas for its potential in cancer prevention, cardiovascular health, and as a natural remedy for menopausal symptoms. Commercially, the root is available in dried powder, capsule, and tincture forms in health‑food stores and online herbal marketplaces, and it remains a staple ingredient in many Korean herbal formulations.
