Incense ash wrapped in cloth, ancient women and modern women have menstruation! As for what ancient women used to make sanitary napkins after menstruation? This is very simple. The ancients knew for a long time that cotton was used to weave cloth. According to textual research, the history of ancient cotton cultivation has been more than 5000 years. More than 30 years ago, in some remote rural areas of China, many women were still using multi-layer cloth to make sanitary napkins. This is a reusable sanitary napkin, which can be used next time after washing and drying. In rural areas, toilet paper is also used to make sanitary napkins. The so-called toilet paper is actually made of straw, which is harder than cloth, but has greater water absorption than cloth, and is a disposable product.
