Gastica Drops helps relieve digestive disorders like alleviating infant colic, griping pain, and flatulence. It contains Dil oil, fennel oil and simethicone. Simethicone works by altering the surface tension of gas bubbles in the stomach and intestines, allowing smaller bubbles to combine to generate larger bubbles. It makes it easier to get rid of gas by belching or passing flatus. Fennel and Dill oils help relieve stomach cramps and stimulate stomach and intestine motility, which helps move food through the digestive system. It may cause bloating, heartburn, dizziness, diarrhoea and constipation.
