In ancient times, there were no laundry products such as soap, washing powder, etc. The ancients tried their best to use natural resources to invent some pure natural laundry products without added ingredients. These laundry products really "don't hurt your clothes and don't hurt your skin"! If the clothes of the ancients were dirty, there were three types of things that could be used to wash clothes - natural alkali, soap horn, and pancreas.
Natural alkali is alkaline soil, which, after drying and dehydration, will produce a layer of white sandy natural alkali on the surface. The ancients collected soil alkali on the surface, swept away a layer, and in the near future will regenerate a layer, and can continue to collect. Every year in spring and autumn is a good time to collect soil alkali, and alkaline soil is edible, belonging to the real "food grade" and "pollution-free" environmental protection washing powder.
As for the soap horn, it is the fruit of the saponaria tree. In ancient times, the laundry function of soap horn became almost the default function of the whole country. The soap horn is mashed to extract pancreatic soap to make soap. It is worth mentioning that saponaria is not absolutely safe and harmless. If a person mistakenly takes two or two soap horn decoctions, he can be poisoned to death. However, the taste of soap horn is easy to discern, so no one should eat it for no reason.
Pancreas is a washing product invented by the ancients, composed of grass and wood ash and pig pancreas. In modern times, pancreas is synonymous with "soap", and in ancient times, pancreas also added scented herbs, and the fragrance was refreshing. Therefore, pancreas are mostly loved by the majority of female friends, and the clothes washed with pancreas are not only clean, but also emit a fragrance. In addition, the fragrance of pancreas made in different stores will vary, and the price will vary.
It can be seen that although the frequency of washing clothes by the ancients was not high, they were never sloppy! The ancient way of washing clothes and the washing products are "diverse", which reflects the wisdom and refinement of the ancient people!
