the pills are ridiculous scams. the plant (i think its a cactus) itself is eaten by natives who use it to supress their hunger during long journeys across plains etc. studies into whether this "unique quality" of the hoodia (cordona(sp?)) can be used in dieting pills is still being carried out. the pills you are thinking of trying dont have any of that breed of hoodia in them as it is still illegal and hasn't been investigated thoroughly enough. they in fact probably have really bad side effects too. won't be long till they have the real hoodia; i personally think they should just import it, grow it in greenhouses, dry it and sell it in holland and barrets.
