Reptilegirl whereas i agree with some of your points, your dismissal of scientific evidence is disturbing.
Untreated pine does have harmful side effects, and that was what the tests were based on. The evidence supporting pine, is all for treated pine, not un-treated.
Un-treated pine does in fact cause health issues in small mammals (comparable [since it's the same thing in a lower dose] to the effects of cedar on small mammals), which is why it is not used in laboratories (mainly the enzyme changes in the liver, which can effect the way an animal metabolizes medications, and reacts to testing).
