These general-purpose analgesic patches with tourmaline are ideal for use on broad areas of the back, thighs or torso, but may also be cut to size for smaller areas such as fingers and toes. They offer the strongest herbal formulation for deep penetration into the tissue. Many practitioners use patches together with creams or spray for maximum effect. The formulae of these patches range, in Chinese herbology, from “cool” to “hot”. The ingredients in the patches are water-soluble therefore it is recommended to remove patches while showering or bathing to ease any possible discomfort. No patch should be worn longer than 8 hours to allow skin to breathe.
