Why buy this?
A vapor rub similar to the one shown has been used for decades to help with the common cold. As said in a number of places, we are reasonably convinced that many of the products advertised to manage the symptoms of the common cold are risky. Therefore, we do not recommend them. The best thing to do for a common cold is do little or nothing and rest and allow your immune system to do its good work. Your immune system regularly and almost inevitably cures the common cold.
