1. Introduction to Agarwood Essential Oil
Agarwood Essential Oil, commonly known as Oud Oil or Agar Oil, is one of the rarest, most luxurious, and highly valued natural essential oils in the world. It is extracted from the resin-rich heartwood of the Aquilaria malaccensis tree. This tree is primarily found in tropical regions such as northeastern India (especially Assam and Meghalaya), Bangladesh, Malaysia, Indonesia, Thailand, Vietnam, and Cambodia.
Under normal conditions, the wood of the Aquilaria tree is pale in color and has little to no fragrance. However, when the tree becomes naturally infected by fungi or other microorganisms, it produces a dark aromatic resin as a defense mechanism. This resin-infused wood is known as Agarwood or Oud. The precious essential oil is then obtained from this resinous wood through steam distillation.
Agarwood Essential Oil is known for its rich, deep, woody, smoky, earthy, slightly sweet, and long-lasting aroma. Due to its rarity, exceptional quality, and high market value, it is often referred to as “Liquid Gold.” For centuries, it has been widely used in perfumery, religious ceremonies, Ayurveda, Unani medicine, aromatherapy, and meditation practices.
