This is the best place to go for further info on the HH program...I have no idea about availability in Canada. Actually...HH used to be readily available in health food stores in Chicago years ago and I only know of one in this area that still carries it. Unfortunately...I believe that it has been replaced in the stores by 'newer' cleanses that contain laxative herbs that give people the impression that they're getting clean...nope...they're just making whatever you put in your face go through you faster so your bowels move more frequently! Too bad...because this in one of the few remaining products that doesn't contain laxatives.
