Old Beijing foot stickers have been posted for many years. The main ingredients in the foot patch are bamboo sticks or ginger powder and wormwood. Generally, the feet are attached to the feet, and when they are taken off the next day, they will find that they are completely black. This is normal, but don't think that those black things are toxins in our bodies, and we are not that toxic. Those blacks are produced by the reaction between the foot pads and your sweaty feet. Therefore, the foot patch only promotes the excretion of your body, speeds up your metabolism, and allows you to excrete moisture from your body.
Moreover, many people like to make fakes, saying that foot stickers are useless, which is completely deceiving consumers, because if you pour some water on the foot stickers, the foot stickers will turn black. That's true. Although the black feet are not toxins, no one says that those black things are toxins. Those who say so are just false propaganda. Foot patch is not a panacea, it just promotes your metabolism and allows you to get rid of moisture yourself, not a high-tech product.
Therefore, for this thing, faith is the spirit, and unbelief is invalid. Call it a fake. Some people do think that sleep has improved after using it, but others think it is useless. So buy it if you think it's useful, and don't use it if you think it's useless. This influence varies from person to person. I can't say it's useless at all, but it's useful. It's also an old Beijing foot sticker. The actual effects of different manufacturers are also different.
