The ancients were good at making use of natural things. As the saying goes, "Heaven and man are one, and Taoism is natural", they complied with nature, worked at sunrise and rested at sunset, and paid attention to when to do and eat.
For example, every summer, the ancients would bathe in wormwood decoction to repel mosquitoes and moisturize the skin, so as to keep the whole body cool and clean.
This method has been passed down to this day, but for busy modern people, it is not realistic to bathe in decoction, so today I recommend a hand-made wormwood soap for everyone.
Hand-made wormwood soap saves people the trouble of picking and boiling, just gently knead the essential oil with warm water, then apply it to the skin and wash it with clear water.
