A method of promoting blood circulation and reducing inflammation, gua sha involves rubbing the skin with a flat tool to facilitate pain relief. When a muscle gets contracted, it receives less fresh blood and oxygen. This contraction and diminished nourishment often lead to what we perceive as pain. With gua sha, we can bring fresh blood and oxygen to the tissues, inviting the muscle to release, and pain and tension to diminish. Gua sha is used to improve local blood circulation, tissue and joint mobilization, and range of motion. Gua Sha also helps in breaking up tight fibrotic myofascial bands and scar tissue, facilitating tissue repair, and reducing pain.
