Less than meets the eye

There is a compound out there, almost ubiquitous and severely unregulated. In fact, according to this website:

Its basis is the highly reactive hydroxyl radical, a species shown to mutate DNA, denature proteins, disrupt cell membranes, and chemically alter critical neurotransmitters. The atomic components of DHMO are found in a number of caustic, explosive and poisonous compounds such as Sulfuric Acid, Nitroglycerine and Ethyl Alcohol.

Should we be more worried about it? Or is there less than meets the eye?
