I just read a warning this morning to not do this if you have cats. The oils are poisonous to cats.
My cats never seemed to care about Vaporub
My wife likes to use an “efficascent oil” for practically every malady she gets. This product is, per the label (weird mix of units), per 100 ml of fluid:
13.846 ml Methyl Salicylate
3.846 g Camphor
0.423 g Menthol
4.615 ml Turpentine Oil
1.0 ml Eucalyptus Oil
color q.s.
Liquid Paraffin q.s.
Our cat (several, over the years) acts almost like this stuff is catnip, and will try to lick it off of a person if given a chance.
We’ve never noticed any ill effect, but...???
