I continue to use Vicks on feet and knee and talking to another health friend, she was talking about turpentine oil for joint pain help. Turns out turpentine oil is an ingredient in Vicks. Vicks has been around for decades+. A similar product to Vicks is Unkers which I am reading about on amazon. It has a pine needle oil which is similar to the turpentine oil origin. I change off a lot but Vicks draws me back to it. Time for a new Vicks application now. C
