15. Barberry Tea
Made from the root, bark, fruit, and even the stem of the barberry shrub, barberry tea contains alkaloid berberine, a fat-frying chemical that helps prevent weight gain. Other health benefits include treatment of fever, renal, and biliary diseases, diarrhea, gout, gastric indigestion, rheumatic symptoms, and dermatosis. It has also been used to treat skin infections such as acne and eczema. Recent studies have proven that consuming barberry tea boosts energy expenditure and reduces the number of receptors on the surface of the fat cells.
