HISTORY OF SANDALWOOD ESSENTIAL OIL

Sandalwood is a luxurious essential oil with an exquisitely soft, sweet, and woody scent that is characteristic of Oriental perfumes and incense. Sandalwood oil comes from the heartwood of trees in the Santalum genus. It is one of the most expensive oils in the world on account of the trees’ extremely slow growth, taking decades to mature before they can be harvested for oil production.

There are approximately 30 species of sandalwood trees that occur throughout Asia, Australia, and the Pacific region but only a few are widely used for essential oil. East Indian Sandalwood from the Santalum album tree is the source of the classical essential oil, which is still considered the best quality. However, due to aggressive overharvesting, this species is now endangered and produces a limited supply of oil. Efforts are underway to increase sustainable cultivation of East Indian Sandalwood. NDA sources its Indian Sandalwood only from licensed producers who purchase the raw material through auctions conducted by the Government of India under strict sustainability controls. As the supply of this oil is likely to remain limited for some time, a popular alternative is an Australian Sandalwood from the Santalum spicatum tree, which is aromatically similar and also easier to sustainably produce.

The use of Sandalwood has been documented back 4000 years, originating in India and spreading through ancient Egypt, Greece, and Rome. Applications for this material were versatile, spanning the aesthetic, the practical, and the spiritual. Ancient Arabs used pulverized Sandalwood to make incense and solid perfumes while in China, Tibet, and Nepal, this thick and hardy wood was used to build sculptures in temples and monasteries. East Indian Sandalwood oil has further been used as an ingredient in traditional Ayurvedic and Chinese medicines for centuries, as part of treatments for the common cold, muscle and digestive problems, infections, inflammation, and to address mental health.

There is a longstanding association between Sandalwood and divinity; the Ancients were fond of building temples and other sacred structures with it, Egyptians used it in embalming and religious rituals, and Indian Muslims burned it as incense to elevate the souls of the recently deceased. Sandalwood still plays a prominent role in Indian spiritual rituals, as it is considered a meditation aid and is often burned on altars as a means of divine communication. In Buddhist practices, it is considered one of three integral incenses, along with Agarwood and Clove.

Today, Sandalwood remains one of the most commercially valuable trees, although its applications have been drastically reduced due to overharvesting and it is now mainly used to produce oil. Inimitably rich and creamy, Sandalwood’s essence is so highly valued and costly that it is often referred to as “liquid gold”, appearing frequently in high-end perfumes and cosmetics. It is further one of the most prized aromatherapy oils, renowned for its superb fragrance and reputed benefits.

SANDALWOOD CULTIVATION & EXTRACTION

Sandalwood trees are elegant evergreens with slender branches, shiny leathery leaves, small pink-purple-colored flowers, and smooth grey-brown bark. While the Santalum genus encompasses over one hundred species of trees and shrubs around the world, most varieties are native to India, Hawaii or Australia. While shrubs can grow up to 3 meters (10 feet) tall, trees can reach a height of approximately 8-12 meters (26-39 feet) when mature and can live up to 100 years.

Sandalwoods are hardy trees, preferring full sun but capable of growing in partial shade and thriving in poor, dry clay or sandy soils. They are also tolerant of high winds, drought, salt spray, and extreme heat. Young Sandalwood trees are parasitic, extending specialized roots into nearby host trees to siphon nutrients for roughly the first 7 years. Trees produce fruit after about 3 years, at which time birds spread their seeds in the wild. For the propagation of plantation-grown trees, seeds are dried and stored for a period of two months, during which time they are dormant, before being sown to produce the next generation of Sandalwoods. Seeds may be treated with an acidic solution prior to sowing to facilitate germination.

Essential oil does not appear in growing trees until they are roughly 30 years old, and their circumference has exceeded 50 cm. Oil first develops in the roots and spreads gradually throughout the tree. The quality of the oil depends on the age of the tree, and It can take up to 60 years before a tree is considered ready for harvest. The most prized (and most expensive!) oil comes from trees that have been allowed to mature for at least 60 years.

Harvest is a delicate process; the trees cannot simply be chopped down because the oil is spread throughout the roots, branches, and trunk. Rather, trees are carefully uprooted, typically in the rainy season when their oil content is at its richest. Once trees have been uprooted, loggers expose them to white ants, which eat the sapwood and bark, leaving behind the oil-rich heartwood. This is light yellow to reddish-brown in color, fine-grained, heavy, and hard. Sandalwood retains its aromatic character for many years, accounting for its historically luxurious status as a building material.

Once collected, the heartwood is turned into a coarse powder to optimize its quality for extraction. Both the powdered heartwood and the roots undergo steam distillation to produce the pale yellow to gold colored Sandalwood Essential Oil (appropriately nicknamed “liquid gold”). The most highly regarded Sandalwood oil is produced in this fashion from the Mysore district of India’s Karnataka region; this is the variety of oil that is used by most famous fashion houses for their fine fragrance lines.
