The best digestive medicine is Gas Hwal-myeong-so.

Donghwa Pharmaceutical's Hyeolmyeongsu is Korea's first digestive medicine. The traditional Hyeolmyeongsu is a synonym for digestive aids. When you have indigestion or bloating, drinking Gas Hyeolmyeongsu gives you a feeling of your nose and mouth opening up. It also feels like the nausea subsides and the blockage starts to go down. Maybe it's just my imagination, but since I trust this digestive medicine, I think it mostly works. So whenever I feel indigestion or my stomach is uncomfortable, I always drink Gas Hyeolmyeongsu. That way, I can naturally feel relief and be reassured in advance.
