Lately, I've seen ALOT of posts about putting Vick's Vaporub in your warmer and that is a NO-NO! If you read the warning label, it says "do not heat". We don't know exactly why, so who knows what you're actually breathing in once the product is heated? Especially those little lungs of your young-ones (and using any non-scentsy product in your warmer voids your lifetime warranty)! So be safe, and use Just Breathe! *Also available in Scent Paks used for Scentsy Buddies for kids!
