Gua sha (Chinese: 刮痧) or scraping, is a healing protocol that involves gently scraping to create transitory therapeutic petechiae called sha which represents extravasation of blood in a problem or pain area. Gua sha encourages circulation and releases unhealthy bodily matter from blood stasis within sore, tired, stiff or injured muscle areas to stimulate new oxygenated blood flow to the areas, thus promoting metabolic cell repair, regeneration, healing and recovery.
Gua sha involves repeated pressed strokes over lubricated skin with a smooth edged and blunt tool. We use a water buffalo horn or jade in our clinic.
Gua sha is most often used to relieve muscle and joint pain. Some examples include back pain, tendon strain, and carpal tunnel syndrome. Gua sha can also benefit the immune system and reduce inflammation. Sometimes, gua sha is used to treat a cold, fever, or problems with the lungs.
Gua sha is generally performed on a person’s back, buttocks, neck, arms, and legs. A gentle version of it is even used on the face as a facial rejuvenation. Your technician may apply mild pressure, and gradually increase intensity to determine how much force you can handle.
What does the color of the “sha” indicate?
Gua sha leaves bruises marks on the skin called “sha” (or “sand” in Chinese).Those “sha” are sometimes known as microtrauma. they create a response in the body that may help to break up scar tissue.
The color of the sha is both diagnostic and prognostic, as it conveys the following meaning:
- Light colored sha= blood deficiency or qi deficiency
- Fresh, red sha= recently contracted condition
- Purple or black sha= long-term blood stasis (slow flow of blood)
- Brown sha= blood may be dry (indicating a lack of oxygen and poor blood quality)
- Dark red sha= may indicate heat in blood (due to inflammation, fever, or agitation)
After gua sha guidelines
In the days following your gua sha treatment, please keep the following guidelines in mind:
- Until the appearance of your skin returns to normal, avoid exposing the treated area to drafts, direct sunlight, or extremes of temperature.
- In cool or windy weather, wear a scarf to cover the treated area. Wear a shirt to cover the treated area at night.
- Drink plenty of water in the three days following treatment.
Although the treated area often feels dramatically less painful and more flexible, be aware that the area is vulnerable to re-injury if it is overtaxed by vigorous activity in the days following treatment.
