Female menstruation is a physiological manifestation caused by endometrial shedding, which is a normal menstrual blood outflow, not a toxin. The color of menstrual blood is black, or it is brown because it accumulates in the vagina and is discharged. Menstruation is neither toxic nor bloody, and there is no such thing as expelling toxin and discharging blood.

If there is a lot of menstrual bleeding, it is recommended to eat iron-rich foods such as pig liver and duck blood, which can supplement iron ions in the blood, or take some blood-enriching foods or drugs. The color of menstrual blood is black or brown because it is easy to accumulate in the vagina and then be discharged.

Women should take medicine to remove blood stasis during menstruation. They can take motherwort, safflower and other drugs directly with water, which also has the effect of removing blood, but it has no detoxification effect.

If there is more bleeding during menstruation, you can eat more iron-rich foods such as pig liver, duck blood and red dates to supplement iron ions in the blood.
