This tea is a weight-loss ninja. The stem, fruit and root bark of the barberry shrub contains berberine–a powerful, naturally occurring, fat-frying chemical. A study conducted by Chinese researchers revealed that berberine can prevent weight gain and the development of insulin resistance in rats consuming a high-fat diet. Previous studies have also found that consuming the plant can boost energy expenditure and help decrease the number of receptors on the surface of fat cells, making them less apt to absorb incoming sources of flubber.
