Gua sha cannot cure a cold, but it helps with recovery from a cold. This is because gua sha can reduce internal heat, promote blood circulation, remove blood stasis, and improve the body's metabolism. To cure a cold, it is still necessary to use cold medicines or anti-inflammatory drugs to achieve a healing effect. During treatment, it is also important to drink more water, urinate frequently, and engage in physical exercise to effectively promote sweating, which can improve the situation. After catching a cold, it is advisable to rest and avoid excessive fatigue. The diet should be light and easy to digest, avoiding stimulating and cold food. (Medication should be used under the guidance of a professional doctor.)
