From the Ly Dynasty (11th to 13th century), the Imperial Court had an organized medical division, which was later changed to a medical institute - one of the first in Vietnam. Under the Tran Dynasty (13th to 14th century) medicinal herbs were planted in an organized fashion, nurtured, collected, managed and used for disease treatment. This record is based on archeological and other records such as the Duoc Son historical remains in Pha Lai- Quang Ninh province. This period was one in which many famous medical doctors made significant contributions to the development of Vietnamese traditional medicine, especially the great physician Tue Tinh, known as the founder of Vietnamese traditional medicine.
