【Details of Ohta’s Isan Sachet】
● Ohta’s Isan is a compound gastrointestinal medicine containing digestive herbal medicine (natural herbs), antacids, and digestive enzymes. It provides gentle and excellent effects on unpleasant symptoms such as overeating, heartburn, and stomach discomfort.
● The effective combination of seven types of digestive herbal medicines improves stomach function and helps relieve unpleasant symptoms such as overeating, indigestion, and stomach discomfort. It is also effective for people with weak stomachs or poor appetite.
● To preserve the effectiveness of the herbal medicines, processing is minimized as much as possible during formulation.
● Antacids with different action times—rapid, sustained, and delayed—adjust the acidity in the stomach and provide excellent effects on heartburn, stomach pain, and stomach discomfort, while making it easier for digestive enzymes to work.
● Being a powder, it preserves the characteristic aroma and effects of the herbal medicines. In addition, L-menthol and antacids provide a refreshing feeling upon intake. Also, as a powder, it acts quickly in the stomach.
