Natural Factors Peppermint Oil - Contains enteric-coated Peppermint Oil combined with Oregano and Caraway. Peppermint and caraway are both traditionally used in herbal medicine to aid digestion and help relieve uncomfortable symptoms of gas. Peppermint and oregano oils have natural antifungal properties that are effective against the growth of Candida albicans. Each ingredient has effective antifungal properties while the enteric-coated softgels deliver the oil directly to the lower digestive tract where it is most soothing for symptoms of irritable bowel syndrome (IBS) and digestive upsets.
