Gua Sha is a traditional healing technique that has been used in Chinese medicine for centuries. During treatment, a practitioner uses a smooth-edged tool to gently stroke or scrape the skin over specific areas of the body. Traditionally, Gua Sha tools were made from materials such as horn, stone, or jade, while modern tools may be made from a variety of smooth materials.

In traditional Chinese medicine, Gua Sha is used to promote the movement of Qi and Blood and address areas of stagnation. From a modern perspective, the technique creates controlled stimulation of the skin and superficial tissues and may temporarily increase local circulation.

Gua Sha is commonly used to help relieve muscle tension, tightness, stiffness, and discomfort. Treatment is often performed on areas such as the neck, shoulders, and back. Patients may experience a firm scraping or massage-like sensation during treatment, but the pressure can be adjusted according to individual comfort.

After Gua Sha, temporary redness or small red or purple marks, traditionally called “sha,” may appear on the treated area. The amount of discoloration varies from person to person and does not necessarily indicate the severity of a health condition. These marks are a temporary response to the treatment and typically fade gradually over several days.
