6. Petrolatum may cause lipoid pneumonia

          Those who rub petrolatum (or petroleum jelly) on dry, cracked face, nose or nostrils to get through a cold or usage of vapor rub which contain petrolatum to apply in nostrils to relieve nose block from having cold might want to think twice. The product is recommended for external use only, which doesn’t include nostrils. What’s more, a rare but scary potential problem occurs if the petrolatum moves from nostrils through the respiratory system. If petrolatum gets into the lungs, it can cause lipoid pneumonia.
