This patches work like Salonpas. Provide cooling and soothing effect and help to relieve : 
 
Headache or migraine - cut the patch and stick on your forehead behind the neck. 
 
Backache, arm and leg pain, rheumatism, shoulder pain etc - paste the patch right at the pain 
 
Stuffy Nose or nasal congestion - cut the patch into smaller patch and stick on the nose bone area and aid in better sleep. 
 
It also works very well with menstrual cramps, chest tightness, flatulence, toothache and swelling.
