Recently, cinnamon tea has been found to aid in weight loss quite effectively and without the harmful side effects of other herbal and chemical supplements. Cinnamon tea blocks some calorie absorption making it effective on those who consume high calories diets. Since no sugar or cream is needed to enhance flavor and cinnamon tea is naturally low in calories, this may be the beverage for the serious dieter. Lastly, cinnamon tea is known to aid in the prevention and treatment of diabetes.
