Angelica gigas Nakai, often called Korean angelica or “danggui,” is a plant species historically used in traditional herbal medicine. It is primarily found in East Asia, with a notable presence and long-standing use in Korea. Its deep, thick roots are traditionally harvested for their medicinal properties. For centuries, the plant has been a consistent component in various traditional remedies.
Unique Chemical Components
The therapeutic properties of Angelica gigas Nakai are largely attributed to its bioactive compounds, particularly coumarin derivatives. Among these, decursin and decursinol angelate are key pyranocoumarins. Decursin, isolated from the root, is a primary active ingredient contributing to the plant’s biological activity.
Decursinol is another related compound that is a common botanical precursor and hepatic metabolite of decursin and decursinol angelate. Nodakenin, a furanocoumarin, is also present and contributes to the overall phytochemical profile. The specific composition of these active compounds can vary depending on environmental factors such as light, temperature, and soil conditions.
Health Benefits and Uses
Angelica gigas Nakai has a long history of traditional use in Korean herbal medicine, particularly for women’s health. Historically, its root has been used to alleviate menstrual pain and manage anemia symptoms. It has also been applied as a sedative or tonic agent and to support blood flow. Traditional texts like ‘Donguibogam’ mention Korean Angelica over 500 times in various prescriptions, highlighting its widespread historical application.
Modern research validates many traditional uses and uncovers additional potential benefits. Studies have indicated that extracts and compounds from Angelica gigas Nakai possess antioxidant properties, which help protect cells from damage. The plant also exhibits anti-inflammatory effects, potentially reducing inflammation in the body. Furthermore, research suggests neuroprotective potential, which could support brain health and cognitive function.
The compounds from Angelica gigas Nakai, including decursin and decursinol angelate, have been investigated for their ability to modulate the immune system. Some studies have explored their potential anti-cancer activities. This plant’s extracts have also been studied for their role in pain management and for conditions like cerebral ischemia reperfusion stroke, metabolic syndrome, and vascular endothelial dysfunctions.
