Natural Factors Soothe Digest - Excellent for soothing the stomach and reducing symptoms associated with indigestion – such as excessive gas and flatulence. Carminative herbs help stimulate peristalsis, which is the wave-like muscle contractions that push food through the digestive tract. They also help relax the smooth muscle of the digestive tract, reducing painful spasms, and the anti-bacterial properties of the volatile oils aid in reducing pain that results from gas that is formed when bacteria in the intestines act on food that has not been fully digested.
