Peppermint Oil
Many studies have shown the effectiveness of peppermint oil in treating irritable bowel syndrome. This is particularly a good option for children and teenagers. These supplements would alleviate abdominal pain which is rather common in people with irritable bowel syndrome. You need to take peppermint oil capsules in several weeks to see whether the symptoms would improve. Ideally, the recommended dosage is around 0.1 to 0.2 mL per day, which can be divided into 3 dosages. A possible side effect of this treatment option is heartburn. [8]
