The agarwood or eaglewood of commerce is derived from the fungus- infected tree through wounds caused by the species of Aspergillus, Fusarium, Penicillium, and also by some of Fungi Imperfecti. Agarwood on distillation yields an essential oil, known as Agar Oil.The essential oil yields a number of agarofurans, sesquiterpene alcohols and spirosesquiterpene alcohols.The stemwood yields sesquiterpe- noids—gmelofuran and agarol; also a coumarinolignan—aquillochin.(Agar is a different drug—extract of a seaweed, Gelidium Amansii, used as a mild laxative.)
Dosage: Heartwood—1-3 g powder. (API Vol. IV.)... aquilaria agallocha
