Dear Lucy: Is it safe to use Vicks VapoRub daily for many months to try and cure a toenail fungus? I’ve seen lots of lay literature talking about this as a home remedy for toenail fungus; however, I could only find one scientific article. This article didn’t mention doing bloodwork or otherwise confirming the safety of the product when used in this off-label fashion, and it also was not a blinded, controlled study.
And how about the safety of other home remedies, such as soaking feet in vinegar or Listerine daily or twice daily for 10–30 minutes? —Vic
