Vicks is my part off life. I have head ache many times but I still using vicks. That time I got feel well. Head ache and body pain and cold like that disease coming time I used this vicks. Other main using is vaporizer. Hot water inside little vicks putting and breathing in the warm. That time I got breath in easily and cold is gone. My better choice is this. My friends your also must be try. No side effects.
