Make your own homemade vapor rub using pure essential oils. Just as effective as Vick's VapoRub, but without toxic ingredients like petroleum jelly.
Recipe for Homemade Vapor Chest Rub
Gently warm and melt your preferred carrier oils, and then add the beeswax (pellets are great, otherwise shave into small pieces). Use a double-boiler, or a canning jar placed in a small pot of water, on very low heat.
As soon as everything is all nicely melted together, remove from the heat and allow it cool down. Once things have cooled down a bit, mix in your favorite essential oils and store in a small glass jar.
This non-toxic version of vapor rub works great applied to the chest and bottoms of feet!
