This liquid has capsaicin as main ingredient which is present mostly in all pain relieving topical application cream or lotion. It numbs the nerve so pain is not felt by the person. It gives temporary relief from various types of body pain like nerve pain, injury, tmj pain, arthritis and many others.
It should not be applied on any open wound or waterline of the body parts. It gives burning sensation so should be applied only on extremely painful area. I found this very helpful in my tmj pain. When ever I feel pain I apply it over affected area gives relief but incase of severe pain it wont be helpful. As the effect of liniment will subside pain will again trouble you. So you will need to search for permanent relief or any pain killer medicine.
