Has anyone here ever used this oil? My mom and sister use it religiously when they get headaches and they swear it dissipates when they use it. I always think it's just in their heads and it's some sort of psychosomatic thing. Especially since it smells exactly like Vicks Vaporub, just in oil form. Anyway, today I had one of the worst migraines I could remember. I finally decided to give it a try and it actually alleviated the pain! As the smell dissipated, I could feel the pain coming back. So, I finally did some research and apparently it's some old Chinese remedy. Anyway, just wondering if anyone here has actually used this.
