Extended data
China has a very long history of using natural spices. In the birthplace of the four ancient civilizations, the earliest time of using spices can be traced back to 3000 to 5000 years ago.
In ancient times, incense was used to burn sacrifices in the activities of worshipping the ancestral temple and the gods of heaven and earth.
During the Qin and Han dynasties, it became common to smoke incense and wear incense in the court. "Han Guan Yi" stipulates that "Shang Shulang holds the orchid with fragrance, and drives away the Dan", and "contains the smell of chicken tongue, and plays things under it", similar to white-collar workers spraying perfume before going to work, and the whole palace is full of fragrant clouds.
During the Wei, Jin, Southern and Northern Dynasties, the spread of Buddhism and Taoism made incense more common among aristocrats, and literati began to write poems about incense. At this time, a number of incense prescriptions for treating diseases appeared. By the Southern Song Dynasty, spices gradually entered ordinary people's homes, and the incense formulas and incense shapes became more abundant.
