Do hot compresses and plasters have the same effect?

The two effects are not the same. Hot compresses can be applied only after the injury has occurred for more than 24 hours. Use a hot towel or hot water bottle to apply local heat to accelerate blood circulation, promote the absorption of exudate in the subcutaneous soft tissue, and reduce edema. There are many types of plasters, which have different functions such as relieving pain, activating blood circulation and removing blood stasis, unblocking the muscles and collaterals, resuscitating the bones, dispelling wind and cold, etc.
