Generally speaking, the higher the oil content of agarwood, the rarer it is, and it can generally sink, because agarwood can sink when the oil content exceeds 1/4. It is generally believed that semi-heavy agarwood can only be regarded as Daphne family. There is such a record about agarwood in Compendium of Materia Medica: "The wooden heart sinks when it is placed in water, so it is named submerged, also known as submerged. Half-sinking is stack fragrance, but not sinking is yellow ripe fragrance. Volunteers in South Vietnam call it honey fragrance, which means that it is as angry as honey spleen. The name of Brahma is Agaluxiang. " The best variety of agarwood is Qinan, which is a fine product in Xiangdao culture. In ancient times, it was used by the royal family as a royal article for blessing, Buddhism and indoor incense. Because of its softness, Runnan is usually made into crumbs for incense. Runnan of the first grade is usually semi-submerged and semi-floating, but it will also sink, but the number is small. When you open the bottle containing Qin 'an, you can immediately smell a cool and slightly pungent aroma. Put it in an incense burner and light it indoors. At first, the fragrance was very strong, and then it spread. If there is, it will pervade the whole house for a long time. This smell makes people feel calm. Besides Qin 'an, Hainan agarwood is the highest price on the market. You can learn all about agarwood directly through Xiang Supreme.
