Gua sha – great traditional Chinese technique – is applied to chronic soft tissue pain with emphasis on restoring normal circulatory function, boosting energy and immune system, improving flexibility, for example in case on the frozen shoulder, extending range of motion and increasing strength.
“Gua” means scraping and “sha” means sand. Sand refers to irregular texture that one palpates as sha rise to the surface. Sha is visible after the treatment and appears as petechiae (small red dots resembling a rash resulting from capillary hemorrhages).
Petechiae appears in tissues where adhesions and scar tissues have accumulated from repeated trauma. From the Easter perspective, abnormal conditions result from blockage of toxins (acidic environment resulting from impaired circulation) that block the flow of chi (the life energy) through the body. Petechiae might be very light (indicates deficiency of blood), red (acute condition which did not penetrate deep into the body yet), purple (indicates blood stagnation), dark brown (dryness in the body and deficiency of fluids).
