A disturbing trend. Bloggers, Pinterest, & Facebook users are recommending to put Vicks in your warmer to help with colds. DO NOT DO THIS. It is very dangerous. Vicks rub is not intended to be used this way, and can ignite. If you want to use your Scentsy warmer, and need a scent that helps with breathing, we have scents such as Just Breathe, & Peppermint Dreams that will help with sinuses. If you prefer Vicks, then please use it as directed, on the label.
