Deodorization, also known as deodorization, deodorization, chicken bone fragrance, wisteria fragrance (not related to the plant wisteria). It is a resinous wood of Dalbergia in Leguminosae. When Dalbergia odorifera is infected by environmental factors (latitude, soil, climate, topography) or external forces (wind, rain, thunder, electricity, insects, ants, birds, etc.). ), in order to protect themselves and prevent the deterioration of health, this tree will start calluses, secrete oil juice of various elements, and then combine with accumulated nutrients to form solid condensate of oil, and finally heal. The longer the time, the higher the density of the oil. After being separated from Bai Shu, it has different volumes and forms different oily substances. "Also known as chicken bone, it has the same name as Aquilaria sinensis."
Mainly distributed in Hainan Province, China. Hainan is rich in Dalbergia odorifera. In Ming Dynasty, Li Shizhen mentioned in Compendium of Materia Medica: "Chicken bone fragrance is odorless" originated in Hainan. Xiangpu quoted Zhou Nanji and also mentioned its origin: "Hainan's mountains are born." Hainan Li people call it La.
Diu (the best spice) is also called Hualigong. Miao people also recorded "Yazhou Records" and "Pear, purple, similar to Dalbergia odorifera" in local ancient books in Hainan. "Gezhi" records that "rosewood is produced in Hainan and Guangdong, and its purple color is similar to Dalbergia odorifera, but it also has fragrance". Hainan Miao people call it agarwood, green agarwood, green fragrant tree and Dalbergia odorifera.
