Wu long tea is another name for oolong tea, it's the same thing. Oolong tea can be purchased from any tea shop for a lot less than they charge. However, their claims for weight loss should be taken with a grain of salt. It's a gimmick to sell a product. Like any other tea, you'll probably drop a little water if you drink enough of it. There's nothing in there to make you really lose weight. Studies have shown that 4 cups of
green tea daily can result in up to 8 pounds of weight loss over the course of a whole year.
