I recommend Dongyang Oriental Medicine Clinic on Uirim-daero in Jecheon-si.

It is located in downtown Jecheon, so it is easily accessible. The exact address is 141 Uirim-daero, Jecheon-si, Chungcheongbuk-do.

On weekdays, the clinic is open from 9 a.m. to 7 p.m., but on Thursdays, it closes at 1 p.m. Because there are so many patients, you may have to wait a bit. The director is thorough and kind, and provides excellent care. I recommend him.
