Gam Tuk-Poh gets ready to make a trip to Jeju Island to visit Jang-Geum.
Jang-Geum makes a bad diagnosis and almost kills Jang Duk so the medicine lady tells her to study the books for now in the cave by the water util she is ready to do intern work.
Min Jung-Ho gets sent on an assignment. The medicine lady is ordered to accompany Min and his soldiers since they may need medical attention. During the medicine woman’s absence, the maids tell Jang-Geum she should practice medicine since the medicine woman won’t let her practice when she’s around. A very ill man is carried to the pharmacy and Jang-Geum discovers it’s Gam Tuk-Poh. Jang-Geum examines gam and realizes he’s suffering from severe side effects of seasickness. The fastest way to treat him is through needle treatment but Jang-Geum is too nervous to treat him via needle so she opts for hot candle treatment instead. Tuk-Poh recovers and the two chat about stuff going on in Han-Yang and the palace. Jang-Geum gets news that the Gam’s only son, Gam Ee-Do died from the a disease, likely polio, but they’re expecting another child. Jang-Geum also gets news of Yun-Saeng and how Lady Choi has banned Gam from the palace and their wine as well, causing a severe shortage in cash flow.
