Scraping Therapy is used to release the body of blood stagnation. Blood stagnation is considered to be the cause of many diseases in TCM (Traditional Chinese Medicine). To visualize this, you may want to compare the water from a running stream versus the water in a still stagnant pond. The stagnant pond will be full of gunk, green moss and other growths while the running stream will have clear water. Our entire blood circulation is very similar to this. When the blood is not flowing properly, it starts to become stagnant and creates an environment more suitable for disease.
This is why Scraping is such a useful technique. It can quickly release blockages in your body caused by stagnant blood. This is because it mimics sweating and promotes body fluid circulation which helps to normalize cellular metabolic processes and release toxic waste from your deep cellular tissues. It also increases blood and qi circulation to help oxidize your cells as well as nourish them.
