Note that the bad stuff in Paragon is the Lacquer Thinner not the Oil of Wintergreen. Oil of Wintergreen has been used for medicinal purposes for years. Its in everything from BenGay to chewing gum.
Lacquer Thinner is also used in other traction compounds...some are labled odorless.
Personally, I would rather have a traction compound with a strong odor that would tip me off to the presence of fumes. This way if I think the smell is to bad I get out of the area. FYI, this is why propane has rotten egg smell added to it.
