Aquilaria sinensis

Background

Kuichenxiang ¿ø³ÁÏã Chinese Name (pinyin): Chenxiang

Chinese Name  :

Common Name  :Eagle Wood

Specific Name  : Lignum aquilariae resinatum

Scientific Name:
Collection  : The drug is collected all the year round, remove from the part without resin and dried in the shade.

Description  : Irregularly lamp shaped, flaky or helmeted sometimes in shreds. Externally lumpy with scars of knife cutting and showing a few holes and streaks formed by black brown resin alternating with yellowish white wood. Surface of holes and depressions mostly rotten wood like. Texture compact, fracture splintery, odour aromatic and taste bitter.

Identification  : 1.Transverse section: Rays 1 - 2 rows of cells, filled with brown resin. Vessels round polygonal, 42 - 128µm in diameter, some containing brown resin. Wood fibres polygonal, 20 - 45µm in diameter with slightly thickened and lignified walls. Interxylary phloem compressed long elliptical or belt shaped often intersecting with rays and the cells thin and nonlignified walls containing brown resin. A few fibres scattered some parenchymatous cells containing prisms of calcium oxalate.2.Microsublime the ethanol-soluble extractives obtained under Extractives, a yellowish brown oily substance with a strongly aromatic odour is produced. To the oily substance add 1 drop of hydrochloric acid, a small quantity of vanillin and 1 - 2 drops of ethanol, a cherry red colour is gradually produced which deepens on standing.Extractives: Carry out the hot extraction as described under the determination of ethanol soluble extractives (Appendix X A) not less than 15.0%.

Processing  : Remove the white rotten wood, split to small pieces or pulverized to fine powder before use.

Action  : To promote the flow of qi and relieve pain, to arrest vomiting by warming the stomach, and to relieve asthma.

Indication  :

Precautions  :

Dosage  : 1.5 to 4.5 g, to be added when the decoction is nearly done.

Storage  : Preserve in a well closed container, stored in a cool and dry place.
