Actually, burning incense is not a patent of China people. In history, there are records of using spices in Egypt, Persia and Greece. Throughout the history of more than 3,000 years, the development of the whole incense culture has also greatly changed the practical function of incense, from the use of religious sacrifices to the embodiment of social values and personal tastes to the application in life, using incense to enhance the living situation, incense clothes and quilts, and purify the environment. The use of incense has moved from high above to daily life. India has to be singled out here. As the birthplace of Buddhism, it is also a world-famous country of spices. The history of Indian perfume industry can only be described in ancient times. At first, sandalwood was used for offering sacrifices and burning incense in a simple sense. Later, it was made into various types of incense with colorful spices, which not only had a strong smell, but also had their own functions. It can be said that India occupies a pivotal position in the history of incense development.
Now the production technology of incense is gradually improving. In modern times, chemical flavors appeared and gradually replaced natural flavors as the main raw materials for fragrance making. Due to the development of chemical industry, synthetic spices (namely chemical flavors) appeared in Europe in the second half of the19th century. These chemical flavors can not only roughly simulate the taste of most spices, but also have easy access to raw materials (such as oil and coal tar) and extremely low cost, so it is easy to produce very rich fragrance. Therefore, it quickly replaced natural perfume and became the main perfuming agent in modern industrial production and perfume industry.
