Inflammation plays an essential role in the development of various human diseases including asthma, rheumatoid arthritis, inflammatory bowel disease, Crohn’s disease, and tendonitis.

However, it is time to be more aware of the importance and potential of herbal medicine in inflammatory process, considering rapidly expanding its use and application.
