The principal & mechanism of far infrared thermal scraping therapy
Scraping (Gua Sha) is an East Asian healing technique which provides rapid pain relief for a variety of conditions whether acute or chronic.
Traditionally it has also been used to treat disorders such as the common cold, bronchitis and asthma.
In the scraping treatment, special oil is applied on a particular area of the skin where the therapist starts "scraping" the area with a "far infrared scraper".
Very soon the places where disorders are hidden, red bruise liked spots appear IN the skin (not ON the skin) comparable to hemorrhage.
Because the scraping is on the oily skin the patient will hardly feel pain - neither during nor after the treatment - the skin will not be damaged, and the red spots will fully disappear within 5 to 10 days. However, in some case, it takes longer to fade due to personal poor blood circulation.
