I had no knowledge of snake oil terms, so I was confused by the "30C is just water". So after reading your comment, I had to go look it up and came across this [0] with description of the terms. For anyone else ignorant of snake oils ;-)
Surely, you're not implying that someone making a snake oil would be doing so in a non-sterile environment without any kind good manufacturing practices being used. These things seem so trust worthy. I mean, even the government feels they need no regulations because they do it so well themselves.
