Foot stickers often contain Zhu Gui, loquat leaves, peppers, tourmaline and so on. Judging from these components, it may play a role in promoting human blood circulation. In addition, because the product contains pepper, it will stimulate the soles of the feet to sweat, and this brown sticky substance will appear after the sweat contacts the foot patch. Not only that, but some people have done related experiments: pouring some water on the foot pad will also cause brown sticky substances on the foot pad, so those "black oils" are not oil and toxins sucked out at all.
There is no way to expand information and lose weight by detoxifying with foot stickers.
It is very unlikely that human oils and toxins will be excreted from the soles of the feet and the skin of the body through drugs. "Human fat can only be discharged by burning into energy or liposuction, and it is impossible to directly suck it out of the skin through drugs." Li Facheng, a plastic surgeon, explained that it takes about two hours to excrete about one kilogram of fat, and the smallest fat particles can't be excreted through the skin. The sucked fat is yellow, not black. Therefore, it is impossible to expect to suck oil by sticking a foot patch.
"Normal acupoint application can stimulate human acupoints and improve blood circulation. It has only a health care function, absolutely no detoxification effect, and there is no saying that toxins are directly excreted through acupoints. " Ding Deguang, chief physician of the Department of Acupuncture and Moxibustion of Hubei Provincial Hospital of Traditional Chinese Medicine, said that Chinese medicine has the method of applying Yongquan point on the sole of the foot. Applying different drugs to Yongquan point on the sole of foot can play the role of warming channels, dispelling cold and inducing fire to return to yuan, mainly treating deficiency-cold diseases, and also has a certain effect on promoting sleep and relieving fatigue, but it has never been heard of detoxification through the sole of foot.
"Therefore, the foot patch can't have the effect of detoxification."
