First, the black mucus on the mat is not a toxin.
Many people like to sleep with a foot pad before going to bed, and the next day they will see something black and sticky on the foot pad, which many people think is a toxin discharged from the body. This is not a toxin. These black sticky substances are exactly the chemical reactions that occur when bamboo vinegar is heated in foot stickers. Because there are many sweat glands on the soles of our feet, when sweat and hot air from the soles of our feet meet bamboo vinegar or wood vinegar, a black sticky substance will be formed.
Second, the foot patch has no health preserving function.
Many people were fooled by the propaganda of the merchants. In fact, the improvement of people's physique depends on normal diet and exercise. The medicines in the foot patch are all powdered, and many other ingredients are added, so the medicinal value of this powdered medicine itself is not high, and the absorption ability of the rough skin of the foot itself is not good, so the medicinal ingredients of the foot patch can only be absorbed by the body for a small part, which does not play a role in health preservation. We'd better take the method of soaking feet with drugs, causing vasodilation through hot air, and delivering drug components through blood is better.
The medicinal components of the foot patch are rarely not absorbed by the human body, and the stimulating effect of the foot patch on acupuncture points is limited, so it does not have the effect of health preservation. The method of keeping in good health also needs to start from our daily life and eating habits. Eat a light diet, don't stay up late, don't drink too much alcohol and tobacco, insist on proper exercise and keep a cheerful mood. This is the right way to keep in good health. Of course, it's not a bad thing to stick a foot patch, and it's ok to stick a psychological comfort patch.
