I recommend Jamshil Terminal Clinic.

The director and staff of Jamsil Terminal Clinic are all kind and friendly. They provide thorough and attentive medical care. Especially, they are famous for Chuna and pharmacopuncture, so please keep that in mind. Someone I know received Chuna therapy with Golt therapy here and said their bone correction was done properly. They also do good posture correction, so if you live nearby and need it, consider visiting.
