This is a bit exaggerated. Old Beijing foot patch is a health care product, which is really good for health, especially for the elderly. It can detoxify and expel dampness, and has a certain auxiliary treatment effect on limb pain of the elderly. If it really has the effect of lowering blood pressure, it is also the psychological effect of the elderly. Generally speaking, old Beijing foot stickers are not expensive, just give the elderly peace of mind.
Note: Old Beijing foot stickers are not sold online or on websites, but only shipped to the general agent. If necessary, please purchase through formal channels. It's better to use fake ones than not to use them, so beware of counterfeiting.
