The egg white is covered with gauze. When the egg is hot, use it to gently push the baby's forehead and temples. After a while, the silver coins will turn black. Wipe the blackened silver coins with firewood ash or cloth, and then repeat the above actions.
Interpretation by Chinese medicine experts: This method is actually one of the external treatment methods of Chinese medicine. Now there are professional scraping devices on the market, which is not as troublesome as before. Wrapping silver coins with egg white only plays a buffering role, and the blackening of silver coins does not indicate the severity of the disease or the effectiveness of treatment. Because silver coins will oxidize when exposed to air, they will naturally turn black. It is recommended that younger infants do not use this method, because children's skin is delicate and easily damaged.
