Introduction
In general, whether the red marks left after gua sha indicate that the body is detoxifying should be determined based on specific symptoms and individual reactions. Avoid friction or irritation before the marks fade, and do not rinse the area with excessively hot water. Maintain a light diet, drink plenty of warm water, and wear loose clothing to reduce pressure. If the marks persist for more than one week or signs of infection appear, seek medical attention promptly.
Generally, whether the red marks left after gua sha (scraping therapy) indicate that the body is detoxifying should be determined based on specific manifestations and individual reactions. The detailed analysis is as follows:
If the marks appear light red or pink, are evenly distributed, and are not accompanied by significant pain or swelling, and if the person feels physically relaxed and experiences relief from fatigue after gua sha, these red marks can be regarded as signs of improved circulation. They indirectly support the elimination of metabolic waste and can be understood as a positive response related to bodily regulation. Such marks typically fade naturally within a few days and require no special treatment.
If the marks are dark purple, bluish-purple, accompanied by obvious stabbing pain, skin damage, or blistering, and if dizziness, weakness, or other discomfort occurs after gua sha, these marks do not indicate detoxification. Instead, they result from excessive scraping pressure causing severe rupture of subcutaneous capillaries, which may even lead to skin tissue damage.
Prior to the fading of the marks, avoid friction or irritation; do not wash the area with excessively hot water. Maintain a light diet, drink plenty of warm water, and wear loose clothing to reduce pressure. If the marks persist for more than one week or signs of infection develop, seek medical attention promptly.
