Safety Overview
1.Aguru — Plant Snapshot
Aquilaria agallocha, commonly known as Aguru or Agarwood, is a distinguished member of the Thymelaeaceae family, renowned for its highly aromatic and resinous heartwood. This medium-sized evergreen tree typically grows to heights of 15-30 meters (50-100 feet), characterized by a slender, often irregular trunk and smooth, light-grey bark that progressively darkens with age. Its leaves are alternate, simple, glossy green, and typically elliptic-oblong in shape, offering a lush canopy. Small, subtly greenish-yellow flowers emerge in axillary umbels, eventually developing into woody capsules, each housing a single seed.
Native to the biodiverse rainforests of Southeast Asia, its natural habitat spans northeastern India, Bhutan, Laos, Vietnam, Thailand, and extends into parts of China and Malaysia. The extraordinary value of Aguru stems from the formation of agarwood, a dense, dark, and fragrant resinous wood. This occurs as a defense mechanism when the tree is subjected to attack by specific fungi, most notably Phialophora parasitica. The fungal infection triggers a complex biochemical response, leading the tree to produce a dark, aromatic oleoresin that impregnates the wood, drastically altering its color, density, and imparting its characteristic complex fragrance.
Historically, agarwood has been revered for millennia, with mentions in ancient texts like the Vedas and the Bible, underscoring its profound cultural, religious, and medicinal significance across diverse traditions. Its exquisite aromatic qualities have made it indispensable in perfumery, incense production, and various traditional medical systems, often playing a central role in spiritual rituals. The escalating demand for this precious resin has unfortunately led to the overharvesting of wild populations, rendering Aquilaria agallocha an endangered species and making conservation efforts paramount.
