agaru:


Morphology:

A large evergreen tree about 21 m in height and 1.5-2.4 m in girth with somewhat straight and fluted stem; leaves linear- lanceolate to ovate- oblong, 5-9 cm long, silky glossy and faintly parallel nerved; flowers small, greenish on very slender pilose petioles in shortly peduncled umbels, on younger branchlets,perianth about 5 mm long, slightly hairy outside, stapens alternate the perianth, filaments red at the apex, ovary tawny- tomentose; fruits slightly compressed, yellowish tomentose casules. Commercially used fragrant- resinous agar wood is formed in the interior of the old tree. The tree contains plenty of oleoresin and has irregular dark patches. The wood burns with a bright flame givingoff a pleasant smell.



Histology:

Aromatics originating from the resin infused infected wood of the Aquilaria and Gyrinops genera have distinct and valued fragrances. Resin formation occurs as a response to internal injury and/or infections in the stems of the agarwood tree. The incenses and perfumes that are prodused from agarwood have been valued for centuries and used by many cultures for spiritual,opulent, and aphrodisiac purposes. Agarwood is highly revered in the seminal texts of Hinduism, Christianity,Buddhism, and Islam. As early as 1400 B.C.E. agarwood  was described as a fragrant product in Sanskrit texts, and in 65 B.C.E, Dioscorides detailed several medical applications for agarwood.
