Agarwood

Agarwood

Aqualaria crassna (Thymelaeaceae)

Characteristics

There are 17 species in the genus Aquilaria, large evergreen trees, and nine are known to produce agar wood. Aquilaria crassna is one source of agar wood, a resinous heartwood, used for perfume and incense. The resin is produced by the tree as an immune reaction in response to infection by mould. Prior to infection, the heartwood is odorless, relatively light and pale colored. As the infection progresses, the tree produces the dark aromatic resin, called agar (not to be confused with the edible, algae-derived agar), which results in a very dense, dark, resin-embedded heartwood.

Distribution

Native to Southeast Asia and New Guinea. Cultivated in plantations in some tropical regions.

Natural Medical Properties

Agar wood is an astringent, stimulant, tonic herb that relieves spasms, especially of the digestive and respiratory systems, and lowers fevers.

In Western, Chinese and Indian medicines the incense is used against cancer, especially of the thyroid gland. In China it is applied as a sedative against abdominal complaints, asthma, colic and diarrhoea, and as an aphrodisiac and carminative.

The grated wood enters into various preparations used especially during and after childbirth, and to treat rheumatism, smallpox and abdominal pains. Decoctions of the wood are said to have anti-microbial properties, e.g. Against Mycobacterium tuberculosis and Shigella flexneri.

Did you know?

First grade agarwood is one of the most expensive natural raw materials in the world, with prices for superior pure material as high as US$ 100’000 per kg. The current global market for agarwood is growing rapidly.

Indian Sandalwood

Indian Sandalwood

Santalum album (Santalaceae)

Characteristics

Evergreen tree, 4-9 m tall. Up to one hundred years old. It parasitizes the roots of other tree species with a haustorium adaptation on its own roots, but without major detriment to its host. Bark reddish to brown (to black), smooth in young trees, becoming cracked with a red reveal. Heartwood pale green to white (“album”). Leaves thin, opposite, ovate, glabrous. Fruit is produced after three years, viable seeds after five. Seeds are distributed by birds.

The plant is widely cultivated because of its valuable wood. Indian Sandalwood (Santalum album) is the primary source of sandalwood and the derived oil. The woods are heavy, fine-grained and unlike many other aromatic woods, they retain their fragrance for decades. Indian Sandalwood still commands high prices for its essential oil, but due to lack of sizeable trees it is no longer used for fine woodworking as before.

Distribution

Native to southern India and Southeast Asia. Now cultivated in India, Sri Lanka, Indonesia, Malaysia, Philippines, Australia and some parts of Oceania.

Natural Medical  Properties

Sandalwood contains 3 – 6% essential oils (predominantly the sesquiterpenols alpha- and beta-santalol), resin and tannins.

It is an aromatic, bittersweet, astringent herb that cools the body, calms the mind, relieves spasms and improves digestion.

It has diuretic, analgesic, antiseptic, expectorant and stimulant effects.

The wood or essential oil is taken internally in the treatment of genito-urinary disorders, fever, sunstroke, digestive problems and abdominal pain.

A paste of the wood is used externally to treat skin complaints.

Sandalwood oil is little used in modern herbalism, its main application is in aromatherapy.

Did you know?

The high value of the species has caused its past exploitation to the point where the wild population is vulnerable to extinction.
