Gua Sha is a scraping method done with a rounded edge instrument like a ceramic soup spoon and massage oil. It feels like a deep tissue massage and is used to improve circulation, relieve tension and pain in muscles, break up scar tissues and adhesions in muscles and fascia, improve breathing and treat body aches associate with common cold and flu. This technique is commonly performed on the neck and shoulders but can be used anywhere on the body to relieve tension. It can produce temporary markings on the skin (petechiae), which typically go away in 3-5 days.
