Who is old enough to remember the old Mustard Plaster? My dad used it on his back...yellow like curry....

You can get similar plasters at a Chinese Herb Doctor. Many types. Not sure if any still use mustard though. They work well!
According to the Wikipedia entry, mustard plasters can be dangerous. http://en.wikipedia.org/wiki/Mustard_plaster
