A natural component found in turmeric, called curcumin, may be as effective as omeprazole in treating gastrointestinal symptoms. Turmeric has long been used in Southeast Asian medicine for the treatment of dyspepsia. In a study, researchers randomly assigned 206 individuals with recurring upset stomach to one of three therapy groups: turmeric, omeprazole, or a combination of both. The study found that all three groups showed significant reductions in symptom severity after 28 days. The researchers believe that curcumin may be a viable option for the treatment of functional dyspepsia.
