It has an ingrediant called camphor. If you put vicks in your nasal passages it's dangerous. Instructions used to be (a long time ago)to heat it upon a teaspoon and swallow it. It killed people because camphor is a poison.
"Exogenous lipoid pneumonia is an uncommon condition resulting from aspiration or inhalation of fat-containing material. Oil-based laxatives such as liquid paraffin and aerosolised oils are most commonly implicated. These substances ellicit a foreign body reaction and proloferative fibrosis in the lung.
