 "http://www.agarwood.org.vn, has studied the formation of resin in Aquilaria and Gyrinops trees and found a method to produce the resin in plantation grown young trees. This technique consists of wounding trees in a specific manner and applying treatments to accelerate the natural defense responses of the tree. The technique allows a sustainable yield of resin to be produced in relatively young trees." \\ "http://www.agarwood.org.vn, has studied the formation of resin in Aquilaria and Gyrinops trees and found a method to produce the resin in plantation grown young trees.

-"The Japanese are great connoisseurs of incenses and consider jinkoh, asthey name agarwood, to be the best. It is the centerpiece in the Koh-do ceremony... The chemical composition of the agarwood scent depends not only on the Aquilaria species, but also on wether the essential oil or the incense smoke is being considered... there is no doubt that the characteristic agarwood note is based on a highly complex accord of many constituents. The sesquiterpene ketones dihydrokaranone and [[http://www.leffingwell.com/chirality/karanone.htm|karanone]] contribute very appealing oriental notes, while even the methoxy ketone 4-(4-methoxyphenyl)butan-2-one is important, with its very soft fruity-floral note, especially to the quality of the incense smoke... an experiment run under the conditions very close to those found in Koh-do ceremony illustrate well the importance of all these sesquiterpenes for the deep noble woody notes. In my opinion, rotundone... is also very important to this part of the agarwood scent." \\+"The Japanese are great connoisseurs of incenses and consider jinkoh, asthey name agarwood, to be the best.

 SPME/GC-MS and Z-score techniques have been applied to analyze the volatile components of high quality samples of agarwood oil from Malaysia. 10-Epi-γ-eudesmol, aromadendrane, β-agarofuran, α-agarofuran and γ-eudesmol were highlighted as significant for high quality agarwood oil and may be used in classifying it. \\ SPME/GC-MS and Z-score techniques have been applied to analyze the volatile components of high quality samples of agarwood oil from Malaysia. 10-Epi-γ-eudesmol, aromadendrane, β-agarofuran, α-agarofuran and γ-eudesmol were highlighted as significant for high quality agarwood oil and may be used in classifying it. \\

 +"...the question of the identity of the key odorants of agarwood is still unresolved, because the chemical complexity and the variability of this material together prevent any “simple” answer. An extensive survey on commercial agarwood essential oil samples of different origins reveals an impressive diversity in their olfactory character, even if their chemical composition is often roughly similar. This situation is possibly due to the participation of poorly characterized trace constituents in the subtle harmony of the agarwood odor. In addition, many odorant components described in early studies are not detected in conventional agarwood essential oils but occasionally reappear in some atypical samples. A consideration of the odor of burned agarwood adds another layer of complexity to this question, as a similar variability exists also in the smell of the smoke obtained from different agarwood samples." \\

The present study indicates that agarwood oil significantly reduced the skin thickness, ear weight, oxidative stress and pro-inflammatory cytokines production in TPA-induced mouse ear inflammation model and contributed towards validation of its traditional use to treat inflammation related ailments." \\ "Traditionally, the bark, root and heartwood are used for their medicinal properties as a folk medicine for hundreds of years.
