Dear Mellow Monk,
I found this page from a Google ad. The "Rare Okinawan Slimming Tea" looks bogus, but I wonder what's really in it? Have you ever heard of it?
The ad says this Okinawan tea is "green tea with jasmine" ... meaning it's simply green tea with jasmine, a very commond blend. Chemically speaking, green tea is green tea. All green tea is from the same species of plant (Camellia sinensis). Although there are thousands and thousands of varieties, none of them has a "secret" weight-loss compound that can't be found in any other variety.
Having said that...
Green tea, although not a miracle weight-loss drug, can help you lose weight. Here are some of my blog postings about green tea and weight loss.
I hope this helps. You know the old saying ... if it sounds too good to be true, it probably is!
