BIG - Here's my understanding of the math: the 2.5cc is the amount being ingested by a hypothetical ferret, not by a 150# human. The human is assumed to be taking 1 tsp/day = 4.921 cc. An equivalent dose proportionately for the ferret would thus be .0656cc, or 4.921cc / 75, because a 2# ferret weighs 75 times less than a 150# human. If, instead of taking this small amount (.0656cc), the ferret is taking 2.5 cc, then the animal is taking 2.5 / .0656 or 38.1 times as much CS per body weight--meaning the ferret taking 2.5cc is ingesting roughly 40 times more colloidal silver per pound of body weight than the human taking 1 tsp/day. The bottom line is that this is more than a whole order of magnitude greater, proportionately, than what humans are consuming. [Moderator's note: Yes.. I was calculating on basis of human getting 2.5cc, not 5cc as note said. You're right. BIG] [Posted in FML issue 1370]
