The biomedical effects of natural products have been increasingly identified. Korean medicine originates from prehistoric times and shares its origin with Chinese medicine. However, Korean medicine, compared with the Chinese medicine, is not well known relatively. Though Korean medicine and Chinese medicine have a lot in common, Korean medicine has developed its own realm by developing unique approaches and research— "Four-Constitution (Sasang Constitutional) Medicine" as one of the diagnostic tools and Saam acupuncture as one of the treatments. In recent years, Korean medicine expanded its usages, thus, by integrating both traditional and modern approaches. Korean medicine covers many complementary and alternative approaches that are actively validated and developed. These efforts in the field of Korean medicine have been, and will be, an important contribution to the evidence-based complementary and alternative medicine.

In the light of these aims, we invite investigators to contribute original basic research articles, as well as comprehensive review articles, that reflect recent developments of Korean medicine as an evidence-based complementary and alternative approach. The contributing authors are encouraged to focus on Korean medicine as a system distinct from other approaches. A summarizing diagram is recommended to deliver the main results of their works. Potential topics include, but are not limited to:

• New drugs discovery and development from natural products
• Current clinical application
• Latest technologies for clinical evaluation and measurement
• Implication of Korean medicine in the treatment of refractory diseases, such as cancer, inflammatory diseases, diabetes, and neuronal disorders
• Biological activities of extracts and isolated compounds from medicinal herbs developed
