What's wrong with that? I often use a millstone myself. I usually walk in high heels, and the soles of my feet are easy to grow cocoons. And especially when the weather is dry in winter, the skin will be cracked and wrinkled, and thick cocoons will grow on the heels. As a girl, she still cherishes the maintenance of her hands and feet, and removing calluses with a grindstone is the most commonly used method.

When I find that the cocoons on my feet are getting thicker, I will boil a large pot of hot water, then pour some white vinegar, soak my feet (in order to soften the cocoons better), put the grindstone in, and consciously rub the grindstone with my feet. After soaking for about half an hour, you take your feet out of the water, and then return them with a millstone. Rub them carefully where there are residual cocoons. Finally, dry the water on your feet and apply body lotion. If the calluses are too thick to be cleaned at one time, put on cotton socks and soak them for several days in a row, which can be well eradicated. But not too often, not too hard, if you don't pay attention, you will easily wear out and thin your skin, just once a week 1-2 times.

And personally, I think it's healthy to do so. Everyone knows that there are many acupoints on the soles of the feet, which are related to our internal organs. The use of millstones can also play the role of massaging acupoints and achieve the purpose of health preservation. Especially in the heel, it is easy to grow cocoons, with male gonad acupoints and female thymus and pelvic cavity. It is very comfortable to grind often. Moreover, the use of millstones can also promote the acceleration of blood circulation, improve the phenomenon of cold hands and feet of women, and improve our body's immunity.
