Women can take salvia powder during their menstrual period. Salvia powder has the function of activating the blood, so women with low menstrual flow or short menstrual cycle can be regulated by taking salvia powder. However, it is not recommended for women with heavy menstrual flow, as this may lead to increased vaginal bleeding and prolonged periods. It is recommended that women should not take any medication during their periods, as many medications may affect their menstrual cycle. Women should pay attention to keeping warm and not getting cold during their periods. They should change their sanitary napkins regularly. As the discharge of menstrual blood will cause dampness in the pubic area, it will easily breed bacteria.
