Herbal patches are pieces of fabric that contain herbal ingredients covered by a layer of adhesive.
Chinese herb patches are used or have been tried for a wide range of pain symptoms, including facial pain, nerve pain, arthritis, joint pain, bone pain, muscle pain and cancer pain. Small experimental trials conducted at a number of different institutions around the world have preliminarily shown that these patches might offer some improvement of pain symptoms when used alone or in combination with other medications.
