Since when was icyhot fatal?!? Maybe she had an allergic reaction to something in the stuff? This falls into the category of "odd"...
That's madness, she must have bathed in it. The LD is 100mg/kg so if she weighed 50kg... well you do the maths. That's a ridiculous amount, especially for a transdermal that is simply supposed to redden the skin.
Yeah this is pretty much what I was thinking. This sort of stuff get used on everyone from kids to athletes to elderly adults with less than stellar immune systems. I'm wondering if this happens to be some sort of freak accident or we're not getting the full story.
She must have been using it a lot over a prolonged period, perhaps the chemical built up over a significant period of time. Thats the only way I can this happening.
