>Anyone can be damaged by improper use of a safe product .. you could >damage yourself if you drank too much WATER, for heaven's sake. That is true. However, no one has yet proven to me that colloidal silver is a "safe product." >That doesn't make the product that you misused inherently unsafe, though. Using a product outside of "recommended usage" can sometimes result in no ill effects, that is true. But doing so without an understanding of exactly what that product does under the full range of its dose-response curve is about as smart as playing "Russian Roulette" with a loaded handgun. In my pharmacology class I was taught that drug manufacturers set their "recommended dose", etc, based on bell curves and percentages. The recommended dose isn't necessarily set to the level where it would gived a maximum therapeutic effect, but to a level where the chances of someone dying or suffering severe side-effects is relatively remote. Therefore, if you misuse a drug, you are wandering into the wilderland into which you might see "interesting effects", potentially positive and potentially very, very negative. (That's my understanding of it, anyway; maybe one of you vet students out there can give a better description. I'm no expert in pharmacology.) Even well-known and widely accepted drugs like acetaminophen (used in meds such as Tylenol and Vicodin) can be extremely dangerous when misused or even taken for long periods at "safe" doses. I'm sure makers of such drugs don't want the public to realize how many liver transplants were necessitated by use of their products. And, argyria is just one KNOWN potential result of the use of silver products. If you had read my post which discussed other possible side effects, you would know that some of these other side effects are not nearly so "visible." Just because a ferret or a person's skin isn't turning blue-grey doesn't necessarily mean they may be experiencing other side-effects. - Megan [Posted in FML issue 2587]
