New research reveals that cinnamon powder is more effective than ibuprofen at reducing symptoms of painful periods (primarily dysmenorrhea) in college age students. Double-blind clinical trial study published in the Journal of Clinical and Diagnostic Research, evaluated the effect of either 420 mg of cinnamon (Cinnamomum zeylanticum), 400 mg of ibuprofen, or a starch placebo, in three groups of 38 females. Both pain intensity and duration were monitored in all groups. Eight hours after the intervention, the pain severity in the cinnamon group was significantly lower than the placebo group (p<0.0001). The researchers concluded that cinnamon can be regarded as a safe and effective treatment for primary dysmenorrhea.
