Aliece (KS) on 12/14/2020:

I have been using either Vick's or Mentholatum ointment products that contain camphor for many, many years. When I blow my nose, I insert a small amount and either on into my nostrils to moisturize the interior and to provide protection against bad bacteria and viruses that might invade my body via the nose. I am rarely sick and will continue to use for the remainder of my life.
