hmmm, I have never heard of it either - heard of green tea, which is supposed to have the same effect on metabolism. I have a pack of it but not sure if it's allowed - but interested to see about the green tea! Will have to look into that!
i'd try organic food shops, coz the polish shops in England usually sell typical polish food, u know, fatty meats, cookies, beer, ready-made soups, etc
