The function of patch is to promote blood circulation, remove blood stasis and relieve pain. The quality of traditional Chinese medicine patch can be achieved by local administration, such as navel patch, carsickness patch and antipyretic patch. Magnetic therapy, far-infrared and other instrument patches will not be effective in a short time unless western medicine or Chinese medicine is illegally added! As for the health sticker you mentioned, it's just a concept. It's no use. Trust him, and you will be fooled! I hope I can help you!
