It is best for women not to scrape when they are having their period. This is because it can easily lead to an increase in the amount of blood in a woman’s period, or a prolongation of her period, mainly because Gua Sha has a certain effect of activating blood and removing blood stasis. If you have a menstrual disorder, you can do gua sha before you get your period, because gua sha can expand the body’s capillaries, unclog the sweat pores, increase the speed of blood circulation, and also relieve the soreness of the waist muscles, allowing the women’s muscles to relax, thus relieving the women’s fatigue and promoting the onset of menstruation. The actual fact is that you will not be able to get a good deal on your own.
