Qi is superior to blood, and liver qi stagnates, which will inevitably lead to blood stasis over time, so it will gradually become swollen, tingling and refusing to press under threat; The liver governs the storage of blood, which is the source of menstrual blood in women. Stagnation of liver blood accumulates in the sea of blood, which hinders the descending of menstrual blood. Bad menstrual blood can lead to amenorrhea and dysmenorrhea.
