If that be the case, you should find the article below interesting. This is a message to the oxylist and is hardly a definitive peer review study. Sounds impressive but doesn't tell you much. There is certainly a politico-economic force actively currupting Science, this does not validate pseudo science nor the BS of oxyscience which blindly accepts anything oxygen as good and harmless and seeks other culprits when the toxic truth of O2 raises its ugly head.
Many toxic substances have medical utility.
Really, nice to hear from an unbiased source.
