The progress of human beings can be seen in the way menstruation is handled. In primitive societies, women used hay leaves to wipe menstruation, and they didn't know much about this physiological phenomenon at that time. Entering the slave society, mankind began to move towards civilization, and women began to make underwear from cloth to cover their shame and rinse their blood with clean water.
With the advent of feudal society, people abandoned primitive objects in favor of silk fabrics. Until today, menstrual treatment has derived more advanced and convenient products such as sanitary napkins and sanitary napkins.
Of course, at the time of menstruation, it was difficult for ancient people to understand this physical phenomenon, and some people even thought that it was inconceivable that women could survive bleeding every month. As a result, menstrual blood is regarded as a filth and even as a descendant of the devil.
The ancient Roman scholar Pliny the Elder wrote in his book that women's menstrual blood can rust steel, wilt crops, and die plants, which is undoubtedly a biased horror. However, with the progress of science and the development of human civilization, we have a deeper and more correct understanding of menstruation. Menstruation, a unique physiological phenomenon of women, not only shows women's fertility, but also becomes an important symbol to measure the progress of human civilization.
