An observational clinical study investigated the effect of a turmeric extract on patients with irritable bowel syndrome. 500 patients suffering from this disease were enrolled and were then treated with 1 or 2 capsules of turmeric extract by mouth for 2 months. The intensity of their symptoms was measured using validated analog visual scales, the quality of life index and a subjective effectiveness evaluation.
At the end of the study, 41% in those who took only 1 capsule and 57% in those who took 2 capsules saw an improvement in their symptoms. In particular, abdominal pain was reduced by 22% and 25% in both cases, with an improvement in quality of life in 36% of patients treated with 2 capsules of extract. Approximately two-thirds of patients rated the treatment as effective, without showing any significant side effects.
