What is in the Body Relief Patches to make them work so well?

The patches are infused with frequencies, not ingredients.  These frequencies number in combination which aids in reduced pain relief. There are no chemicals or herbs applied to the patch. This product is not a substitute for medical treatments. It is for pain relief, a 10 to 4 or a 10 to a 6 or 2.  Depends on the type of pain and varies from individual.
