Quick and effective against heartburn Due to its outstanding acid-binding capacity, Luvos healing clay acts as a natural antacid, as it quickly and effectively neutralizes excess stomach acid. Heartburn is caused by stomach acid that flows into the more sensitive esophagus and attacks the mucous membranes there. The result: burning and stabbing pain. These symptoms are effectively alleviated by binding the acid, which is achieved naturally with Luvos healing clay. It has also proven to be effective in treating diarrhea, which is often caused by certain bacteria or their metabolic products. Luvos healing clay binds these and excretes them in the stool.
