I've been using Vick's for over 15 years. Before I knew you could get your own parasite meds this was my only relief. I would put it on my whole body to kill the filaria while I slept. In retrospect I think I would have died without the Vick's.
I stopped using it after I read Dr. Clark's book because she warns that it has a chemical contaminant that goes right to the liver. I've went back to using it because nothing works better for killing the filaria in the skin.
It works great for toe nail fungus which anyone that has had parasites forever has.
I've known people who put it up their nose but I don't go that far.
BTW There are some that think hemorrhoids ARE caused by pin worms. I think this was Dr. Clark's contention also.
