Aquilaria sinensis refers to wood containing resin in Aquilaria sinensis.

Strictly speaking, agarwood is a paste-like agglomerate formed by the oil produced by trees in the process of self-repair, which is infected by bacteria after being struck by lightning, bent by wind, moth-eaten or man-made destruction, and its wound is corroded and parasitized by fungi under the influence of hot and humid environment. This coagulated paste is agarwood, and the wood that produces the paste belongs to Daphne family.

Second, the use of agarwood

1, incense.

As a first-class agarwood, it can be used for incense. Generally speaking, the agarwood used for incense mat activities is first-class agarwood or chess incense, and the medium-high agarwood can be used for daily incense or fried with an electronic incense burner.

Classification method of agarwood:

1, press the origin

Generally speaking, the grade of agarwood is divided according to the origin, aroma and resin content. The aroma of agarwood from the same place of origin is often very different. Whether this phenomenon is related to microorganisms and environmental factors deserves further discussion.

2, according to the specific gravity

In Korea and Japan, agarwood with resin content over 25% can be used as medicine; It can be set above 15% in China. The specific gravity of agarwood logs is about 0.4, and the specific gravity varies greatly with the oil content in agarwood. The oil content can be determined by the change of the specific gravity of agarwood, which is generally divided into agarwood and non-agarwood.

The reason why people are submerged is because there is more oil (balsam) and the proportion has increased, so the price is much higher than that of people who are not submerged.

3. According to the oil content

Aquilaria experts pointed out that agarwood has been divided into four grades since ancient times: the first-class agarwood has no white wood and is full of oil; The second grade agarwood has less white wood, and the oil content accounts for more than 70%; The third-grade agarwood and white wood are a little more, and the oil content accounts for more than 50%; There are more fourth-grade agarwood and white wood, and the oil content only accounts for more than 20%.

4. Divide by color

There are different opinions about the color classification of agarwood. Generally speaking, what is considered black and shiny is the top grade. According to Chen Rang's Overseas Yi Shuo, agarwood has five colors: one is green, the second is dark green, the third is golden yellow, the fourth is yellow, and the fifth is black. In general, it is considered that the color of agarwood resin is black, but in fact, black is rare in agarwood with high resin content.
