Technology from our research is used to produce agarwood in plantations. We have set up an internet company to help the farmers in Vietnam sell their products and you can find agarwood for sale at: ScentedMountain.com
The agarwood chips and agarwood powder sold by Scented Mountain is pure "raw" agarwood right out of the tree so it would be as "food grade" as you can get.
