I agree that this will do nothing more than if you bought regular green tea or oolong tea from a local store-it is just going to be more expensive.
What also worries me about this, is that one of the "as seen in" publications to the left of the screen there is the book by Kevin Trudeau-who is a widely known "scam artist". He does all sorts of books, infomercials, and other things-and every 10 minutes it is about a different miracle product.
Your local health food store, or even some grocery stores will have all of the teas you need.
Green tea, white tea, black tea, herbal tea-they all have wonderful properties to them-but none really provide weight loss, sorry to say.
