Well, just the "over-the-counter" stuff, non-pharmaceutical. Most of it is for topical application and doesn't require a label.
Some folks just sprinkle with it, others require total immersion for external application. Eh?
Any industry or educational facility that uses distilled water in 1 gallon or larger containers is required to have a Material Safety Data Sheet (MSDS) for it. The reason according to the EPA is that in those quantities the container could drop on your foot and cause a bone to break.
I find that depending upon the weather, the temperature of the DHMO; if applied in great amounts to the body; can have quite an enjoyable or a not-soon-to-be-repeated effect to me.
I have found that there is GREAT difference in opinion among theologians about the timing, amount, method and any wording pronounced at the event of DHMO application to the human body.
Many even debate the effects of such for YEARS!
