Queen Myeongseong was the wife of King Hyeonjong, the 18th king of the Joseon Dynasty, and the mother of King Sukjong. The clinical records of Queen Myeongseong are summarized on the basis of the Seungjeongwon Ilgi (The Daily Records of Royal Secretariat of Joseon Dynasty 承政院日記) and reviewed through Donguibogam. Queen Myeongseong gave birth to one male and three female children in the time of the queen. She took Geumgaedangguihwan (金櫃當歸丸), Dalsaengsan (達生散), Antaeum (安胎飮) during her pregnancy and Gungguitang (芎歸湯) during postnatal care. Since 1669, chest tightness, sleeplessness, arm pain and numbness of arms had been appeared. Ondamtang (溫膽湯) and Dodamtang (導痰湯) were used but they were not effective. However, when her symptoms were regarded as a benign tumor due to cold and wetness, there was a difference in the use of Ohjuksan (五積散). In 1683, when king Sukjong was caught in a smallpox, she took care of him. She exorcised in the middle of winter to pray for her son's recovery, and died of the flu.
