Dwibhashi's OMU Water is an herbal preparation commonly used to support digestion. However, there is limited scientific evidence regarding its safety and the appropriate frequency or dosage during pregnancy. Therefore, pregnant women should not start taking this product without consulting their obstetrician. If your doctor recommends its use, they will advise the appropriate amount and frequency based on your stage of pregnancy, symptoms, and overall health. Avoid self-medicating or consuming it in larger quantities than advised during pregnancy.
