Why Is Silverware or Egg Rubbing Therapy Used for Body Aches and Fatigue Caused by Weather Changes?

Gua Sha (Scraping Therapy) is a traditional folk remedy used to alleviate symptoms such as colds, headaches, nasal congestion, and neck stiffness. This method stimulates the bladder meridian system, helping to regulate energy flow (Qi), improve blood circulation, and enhance overall body function.

The use of silver in this therapy has a scientific basis. When the body is fatigued, the level of sulfur-containing compounds increases, reacting with silver to form blackened silver sulfide (Ag₂S). The degree of blackening on the silver reflects the level of physical fatigue. Additionally, silver has antibacterial properties, which explains its historical and modern use in food storage and utensils.

Using egg whites in this therapy helps close the pores that have expanded due to friction, preventing harmful external factors from entering the body.

However, it is important to note that Gua Sha is a folk remedy and should not replace modern medical treatments. If symptoms persist or worsen, consulting a doctor is advised.
