Many people don't understand what agarwood is. If you want to distinguish between true and false agarwood, you must first understand what is agarwood.

Aquilaria spp, Chinese name is Thymelaceae, Aquilaria genus. The plants of the genus Aquilaria have been widely distributed. They have been distributed in Egypt, India, Vietnam, Myanmar, Indonesia, Taiwan and Hong Kong, and Hainan, China. However, due to the climate, the current Aquilaria plants are only distributed in Southeast Asia. There are some low-grade varieties of live agarwood grown in Guangdong, China.

Agarwood is also divided into three major stages. It is called “Agarwood Stage”, “Activated Agarwood Stage” and “Death and Agarwood Stage”. (Please note that these three names are the definitions of the names of the stages, and some people who are unclear are interpreted as the varieties of agarwood. This is not true. These two titles are the basic definition of the stage of agarwood, not the variety. The following is a description of the stages of these three agarwoods. Everyone must look slowly. Those who have not figured out the names of these three stages are simply not qualified to talk about the true and false of Aquilaria.

In a broad sense, the things in the above three stages are agarwood, and some people only narrowly believe that the dead agarwood is agarwood. This is a factional battle. The three stages of things are classified as agarwood, because the relationship between these three things is like a person's life, people have "children", "youth", "strong" and "old age", four stages. To deny that the first two stages are not agarwood is like denying that children and young people are not human beings and only the elderly are human beings.

1. The plants of the genus Aquilaria in the genus Rutaceae are invaded by fungi when they are alive due to the damage of the trees themselves. Under the action of the bacteria, the starch in the parenchyma cells of the trees produces a series of changes. Form a balm. After years of deposition, it has been fragrant. At this stage, the appearance of the agarwood tree still maintains the appearance of the tree, so this stage is called the “ Agarwood Stage” . The natural state of the agarwood tree is unscented, and the unfamiliar person can't recognize it, so there is a story about someone who uses the agarwood tree as a common tree to burn charcoal.

2. The stage after the fall of the agarwood tree is called live agarwood , and the lodging of the trees is divided into natural lodging and artificial felling. As the secretion of agarwood tree balm is more and more, the original loose material becomes hard, and the growth stage attracts the fungus to parasitize the heartwood, which leads to symbiotic changes, the color of the tree heart changes, and the hardness is also gradually increased. At this time, the tissue of the nutrient is transported. Blocked and let the growth stop, the trunk fell because it could not support the weight, which is called "natural lodging." The artificial lodging refers to the generations of agarwood sellers who bury the agarwood and bury it, leaving the book to the future generations as a legacy, telling the children and grandchildren where there is a scent of scent, it will take several generations to dig up. These have just fallen, and the time has been called "live agarwood" for more than ten years. Because live agarwood is not decomposed by fungi for a long time, it is generally similar to the bark of a living tree or the wooden block of a tree. The basic characteristics are similar to those of a living tree. The basic description is the broken pieces of the tree. This stage is called the “live agarwood stage”. Generally, this live agarwood is used to make Buddha's fragrance, because the live agarwood is naturally fragrant and needs to be burned to volatilize its own fragrance. Therefore, when people distinguish between true and false live agarwood, people will light a little to smell their own taste. This process of identifying live agarwood must be operated by professionals, because the key to distinguishing live aloes is the taste after burning, only the smell The people who sink the fragrance can distinguish true and false from the taste. Those non-professionals who have never heard of agarwood do not advise them to do this, because after burning, it is only a waste of aloes, and I don’t know if this taste can't be distinguished.

3. If live agarwood is placed on the ground without harvesting, the agarwood trees have sunk into the earth for hundreds of years, and are decomposed by the fungus of the soil. The fungus has turned the wood that cannot withstand corrosion, leaving the immortal Wood is the "dead and agarwood". Because it is a fungus decomposition, the dead agarwood has different shapes, and the appearance is different from the living tree! Therefore, after the death of agarwood, the agarwood light can not be determined from what kind of tree was originally evolved. It can only be distinguished by taste. Or use scientific instruments to analyze their cells. Please note here that the similar varieties of agarwood lines are basically the same, so the same lines of dead agarwood may have evolved from different tree species, so the same lines have different flavors. The grain is unable to finally determine the tree species. There are only two methods for determining the tree species. One is the smell of people who are familiar with the various flavors of the tree species. The other is to analyze the cells with an instrument. The same structure of cells is the same kind of agarwood. The basic appearance is that the dead agarwood has basically no characteristics of the living tree, just the part of the hard wood that contains the oil. Dead agarwood is not directly taken from a kind of wood like sandalwood, nor is it directly taken from a resin like dipterocarp, but a dense solid agglomerate mixed with gum, resin, volatile oil, wood, etc. ingredient. In the natural state, the dead agarwood can evaporate the spirit of elegance and elegance. Therefore, the identification of dead agarwood does not need to be burned, because the natural state is its original taste, and some of the dead agarwood after burning is not good. The identification of dead agarwood is not a method of identification of live agarwood. It is still necessary to distinguish between dead and agarwood by taste. At present, there is no fake in the world that can completely simulate the taste of agarwood and can only be similar. The appearance can be imitated.
