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.

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.
