Gua sha has various advantages. As seen by Gua sha's instant effect on coughing and wheezing, it relieves spasms and pain and stimulates proper circulation to the muscles, tissues, and organs. Gua sha has demonstrated its ability to generate a four-fold increase in microcirculation of surface tissue, as well as reduce inflammation and boost the immune system, according to research. Gua sha increases the activity of heme-oxygenase-1 (HO-1) in the body, which helps to reduce inflammation in internal organs in conditions like asthma, hepatitis, and liver illness.
Gua sha is a traditional Asian medical treatment that has been practiced for centuries. Gua is a Chinese word that means "to rub" or "to press." Sha is a phrase that describes blood congestion in surface tissue in regions where the patient may experience stiffness and pain; it is also the name for the small red dots that are generated when Gua sha is applied, known as 'petechiae'. The little red specks fade into a reddish patch after a few minutes. After treatment, the sha vanishes in two to three days. The hue of sha and the rate at which it fades can reveal health information about a patient’s condition. Pain relief lasts even after the sha is completely gone.
