I recommend 'Dasreum Oriental Medicine Clinic' in Ara-dong, Jeju. I often buy and take the digestive medicine that they produce and sell themselves when I feel indigestion or have trouble digesting food. The digestive medicine sold here works very well. Even though it's far from my house, I come frequently to buy their medicine because it's effective. I recommend 'Dasreum Oriental Medicine Clinic' to those who have similar concerns with indigestion.
