Peppermint oil comes from the mint family, which is known to be nutrient rich. Taken orally, it is often used as a digestive aid. The enteric coating used on Vitabase Peppermint Extract Gels keeps the oil from breaking down in the intestinal tract, protecting it until it reaches the small intestine, where peppermint is most effective in addressing digestive conditions. This also eliminates the aftertaste that often occurs when ingesting peppermint. The formula also includes fennel oil and ginger oil which provide synergistic benefits to the intestinal tract.
