This is a very odd product. It's a knock-off of Phen-Phen, which has been banned. Hops, by the way, is a relaxant herb, also used in beer making. Ginger isn't at all like capsaicin, which is from cayenne, and not nearly as hot, but the heat is being used in this product as a theory that says heat makes you lose weight. Ginger is most used as an anti-inflammatory, is good for the liver, circulates blood, helps with motion sickness -- a great herb though useless for losing weight.
