@Naturopathicguy I'm with you - I know "they" all say DMSO is okay in plastic - and is sold that way a lot - but I'm a purist also, and have only bought it in glass. Theoretically it is supposed to be okay in the right plastics, but hell, "they" tell us all kinds of things are safe or okay that aren't. In the U.S. , DMSO is not being sold as something to be ingested or used on the body, so a little impurity wouldn't be a problem. Since it is such an uber-solvent, the plastic bothers me too. Maybe it's overkill, but it bothers me psychologically, so I buy glass.
