Gua sha stones are smooth, flat tools traditionally used in Chinese medicine for a practice called gua sha. They are typically made from materials like jade, rose quartz, or other types of stone. The stones are used to scrape the skin gently, promoting circulation and helping to relieve muscle tension. This technique is believed to enhance the flow of qi, or energy, in the body. Gua sha can be applied to various areas, including the face and body, and is often used as part of a holistic approach to wellness. Many people find it beneficial for relaxation and improving skin appearance.
