AQUILARIA
aka Agaru (Sanskrit), Agarwood, Aloewood, Eaglewood, Gaharu (Malaysian), Kaha gaharu
(Aquilaria malaccensis syn A. agallocha)
imageImage
Also: A. sinensis (China) and A. crassna(Cambodia)

A tropical to semi-tropical tree which is valued in Asia as a decorative, fine-grained wood, and for its fragrance which resembles sandalwood. It has a long history of use in Chinese, Ayurvedic, and Unani traditional medicines. Also used are the Chinese A. sinensis which is a substitute for A. malaccensis and A. crassna which is from Cambodia. The name of the species is derived from the Latin "aquila" meaning eagle.
The fragrant wood only develops when the tree is dying (thought to result from a fungal infection). Dark, hard fragrant lumps develop, embedded in the normal wood. The demand has endangered the species as perfectly healthy trees are cut down.

CONTAINS: Benzylacetone, p-methoxybenzylacetone, terpene alcohol.

PROPAGATION: Fresh ripe seed sown at 66-77 F. Seeds are short-lived. Germination is in 15-30 days. Young trees are planted out when growth is between 24-32 inches and in a shady site.
NEEDS: Well-drained humusy soil in part shade with good humidity. Minimum temps should be 59-64 F.
HARVEST: Heartwood and bark are taken from trees at least 50 years old or those in the process of dying. These are then dried for decoctions or distilled for their resin.
PART USED: Bark, wood, resin.

A. sinensis [chen xiang] is a tree of SE China which is replacing A. malaccensis in traditional Chinese medicine. Harvesters wound the trees to induce secretion of resins which are collected regularly. The wounds heal and the wood around the old wounds is cut off for use. This in turn causes the formation of new wounds and the secretion of more resin, so the process is ongoing. Old and dying trees are cut down and the heartwood harvested for medicinal use. The resinous stem has been used for abdominal pain, abcess, chest pains, weakness in the elderly, high blood pressure, liver, shortness of breath, nausea, chills, gas, pain, weak knees. The resinous wood and the resin are considered tonic for the kidneys, and have been used to expel gas, to treat male disorders, shortness of breath, nausea, general pains, weak knees, chills, chest and abdominal pain, and asthma.
