The study, published in BioMed Central's open access Nutrition Journal, has described how the juice of mangosteen lowered levels of C-reactive protein.
Dr. Jay Udani, M.D. from Medicus Research, California, worked with a team of researchers to carry out a randomized, double-blind placebo controlled trial.
He said, "For people drinking over half a liter of mangosteen juice a day, the degree of reduction in CRP levels was statistically significant - a reduction of 1.33mg/L compared to an increase of 0.9mg/L in the placebo group".
Inflammation, as measured here by CRP, is a predictor of cardiovascular disease and a precursor of metabolic syndrome. Reducing inflammation in obese people is a treatment goal, and a natural treatment may be preferable to other treatments which may carry the risk of side effect.
According to Udani, "Further studies with a larger population are required to confirm and further define the benefits of this juice, which was safe at all dosages tested".
