Ginkgo Leaf: Traditional Use in Traditional Korean Medicine (TKM).


Traditional Korean Medicine (TKM), also known as Koryo Medicine or Oriental Medicine, is a holistic healthcare system that has been practiced for centuries in Korea. Rooted in ancient East Asian medical traditions, TKM encompasses various treatment modalities, including herbal medicine, acupuncture, moxibustion, and cupping therapy. Among the many herbal remedies used in TKM, ginkgo leaf (Ginkgo biloba) holds a special place. This article explores the traditional use of ginkgo leaf in TKM, its historical significance, therapeutic properties, and its continued relevance in modern healthcare.

Historical Background of Traditional Korean Medicine

TKM has a long and rich history that dates back over 2,000 years. It evolved from a fusion of indigenous Korean medical practices and influences from Chinese medicine, particularly the theories of Traditional Chinese Medicine (TCM). The foundation of TKM is based on the concept of balancing vital energy, or Qi, and the harmonious flow of Yin and Yang forces within the body.

TKM practitioners diagnose patients by assessing their Qi, blood, and bodily fluids, as well as examining their pulse, tongue, and overall physical condition. Herbal medicine plays a significant role in TKM, where a wide range of natural substances, including plant materials like ginkgo leaf, are used to restore harmony and treat various ailments.

Ginkgo Leaf in Traditional Korean Medicine

Botanical and Historical Overview:

Ginkgo biloba, commonly known as the ginkgo tree, is one of the oldest tree species on Earth, with a lineage dating back to prehistoric times. The use of ginkgo leaf in traditional medicine can be traced back to ancient China and Korea. Ginkgo trees are known for their distinctive fan-shaped leaves and their resilience to environmental stressors.

In TKM, ginkgo leaf is often referred to as "Eunhaeng" or "Ipgak" and has been traditionally used for its therapeutic properties. Historical records suggest that ginkgo leaf was used to treat a variety of conditions, including respiratory ailments, cognitive issues, and circulatory problems. Its use in TKM reflects the deep appreciation for natural remedies that support overall health and well-being.

Therapeutic Properties in TKM:

In TKM, ginkgo leaf is believed to possess a range of therapeutic properties, and its use is typically tailored to specific conditions. Some of the key therapeutic properties attributed to ginkgo leaf in TKM include:

Promotion of Circulation: Ginkgo leaf is thought to improve blood circulation and enhance the flow of Qi, making it valuable for addressing conditions related to poor circulation, such as cold extremities and varicose veins.

Respiratory Health: Ginkgo leaf has been used to address respiratory issues, including asthma and bronchitis, by helping to clear phlegm and reduce inflammation in the respiratory tract.

Cognitive Enhancement: TKM traditionally employs ginkgo leaf to support cognitive function. It is believed to enhance memory and mental clarity by improving cerebral blood flow and oxygenation.

Anti-Inflammatory Effects: Ginkgo leaf is considered to have anti-inflammatory properties and is used to alleviate symptoms of inflammatory conditions, such as arthritis and joint pain.

Antioxidant Action: In TKM, ginkgo leaf is seen as an antioxidant that can neutralize harmful free radicals, contributing to overall health and longevity.

Reduction of Edema: Ginkgo leaf is used to reduce edema (fluid retention) by promoting the elimination of excess fluid from the body.

Vision Support: Ginkgo leaf is traditionally employed to support vision health, particularly in cases of eye fatigue and poor vision.

Traditional Formulations and Preparations:

Ginkgo leaf can be administered in various forms within TKM:

Decoctions: Ginkgo leaf can be boiled to create decoctions that are consumed as herbal teas. These decoctions are tailored to address specific health concerns.

Powders: Dried ginkgo leaf can be ground into a fine powder, which is then encapsulated or mixed with other herbal ingredients to create medicinal powders.

Topical Applications: In some cases, ginkgo leaf is used topically in the form of poultices or ointments to address skin conditions and reduce inflammation.

Combination Therapies: TKM often combines ginkgo leaf with other herbal ingredients to create synergistic therapeutic effects. These combinations are carefully selected based on individual diagnoses.

Modern Scientific Research on Ginkgo Leaf:

While ginkgo leaf has a long history of use in TKM, modern scientific research has also explored its potential health benefits. Some of the findings include:

Cognitive Function: Several studies suggest that ginkgo leaf extract may improve cognitive function and memory, making it a subject of interest in addressing age-related cognitive decline and neurodegenerative diseases like Alzheimer's.

Circulatory Support: Ginkgo leaf has been shown to enhance blood flow and may be beneficial in conditions like intermittent claudication (painful leg cramping due to poor circulation).

Antioxidant Properties: Ginkgo leaf extract exhibits antioxidant effects, which can help protect cells from oxidative damage.

Anti-Inflammatory Activity: Research suggests that ginkgo leaf may have anti-inflammatory properties that can be relevant in the management of conditions like arthritis.

Vision Health: Some studies indicate that ginkgo leaf extract may support eye health by improving blood circulation to the retina.

Safety and Tolerability: Ginkgo leaf extract is generally well-tolerated when used at recommended doses. However, like all herbal remedies, it should be used under the guidance of a healthcare provider, especially when considering long-term use or interactions with other medications.


Ginkgo leaf, known as "Eunhaeng" or "Ipgak" in Traditional Korean Medicine, has a rich history of use for its therapeutic properties. It is regarded as a versatile herbal remedy with applications in addressing circulation issues, respiratory ailments, cognitive function, and various inflammatory conditions. While traditional knowledge underscores its importance, modern scientific research continues to explore and validate its potential health benefits.

In an era where natural and holistic approaches to healthcare are gaining popularity, the traditional use of ginkgo leaf in TKM remains relevant. Its incorporation into modern healthcare practices, when guided by scientific evidence and professional expertise, highlights the enduring significance of herbal remedies in promoting health and well-being. As research continues, ginkgo leaf may continue to play a valuable role in integrative healthcare strategies, bridging the wisdom of ancient traditions with contemporary understanding.
