by Robert A. Blanchette and Henry Heuveling van Beek
A method of producing purified agarwood resin comprising:
(a) producing agarwood by a method comprising forming an artificial wound into the xylem in an Aquilaria or Gonystylus tree, and providing a means for aerating the wound, wherein the means for aerating is a perforated tube or pipe, and
(b) purifying the resin from the agarwood.
“Agarwood is a highly prized incense that is extremely rare. It has at least a 3000-year history in the Middle East, China and Japan. There are also references to agarwood in the literature of India and France, and even in the Old Testament of the Bible. Agarwood remains today the world’s most expensive incense. The value of agarwood shipped out of Singapore alone each year has been estimated to exceed $1.2 billion.”
“The resin is used by Traditional Chinese, Unanai, Ayuravedic, and Tibetan physicians. Used medicinally, agarwood is a remedy for nervous disorders such as neurosis, obsessive behavior, and exhaustion. Agarwood is highly psychoactive and is used in spiritual rituals. Many religious groups prize it as a meditation incense, to calm the mind and spirit. In Ayuravedic medicine it is used to treat a wide range of mental illness and to drive evil spirits away. In Japan, it is considered by many to be sacred, and is used to anoint the dead. In Buddhism, it serves as a major ingredient in many incense mixtures, and it is considered to be one of the three integral incenses, together with sandalwood and cloves.”

This invention is mainly about the making of wounds on the Aquilaria’s trunk in order to stimulate the process of Aquilaria resin formation. The wounds in this invention include details of wounds made on the Aquilaria’s trunk with the specifications of shape, location, size, beveling, gouging, making holes, and the method of leading the stimulant to Aquilaria through the wounds. The details are shown in this invention.
The methods begin with the selection of Aquilaria trees, which have a diameter of about 50 centimeters. Then make a square shaped wound on the trunk with the size and position as specified in the details of the invention. The rims will be gouged as the small channel. Inside the square, make many holes deep into the heartwood. These holes will stimulate Aquilaria to release resin and it is easier to use the stimulant to merge the wounds. In proper time, the resin can be collected and used for further benefits.

The present invention relates to a novel process for extracting oil, waxes and resins from Agarwood (Aquilaria Agallocha synonimus with Aquilaria malaccansis) by super critical fluid extraction method using CO2 as a solvent comprising pumping liquid carbon dioxide by means of a high pressure pump through the super heater to achieve carbon dioxide super critical state, at critical temperature and pressure, filling an extractor with pulverized agarwood, passing the carbon dioxide in super critical state through the extractor, passing the said extract along with the super critical carbon-dioxide through a separator maintained at desired temperature and pressure to remove the carbon-dioxide, removing the solute from carbon dioxide, recycling the said carbondioxide in the system.
