About Indian Sandalwood Oil

Indian sandalwood (Santalum album) is one of the most revered plants known for over two millennia for its medicinal, cosmetic, and religious significance. Main qualities of Indian sandalwood are attributed to the essential oil found only in the heartwood of the tree. This essential oil is comprised of over 125 components; however, its two main sesquiterpene alcohols, namely alpha and beta santalol, render the unique sweet, lactonic woody aroma of Indian sandalwood with multi-faceted benefits.

Indian sandalwood grows in several different climatic and topographical locations based on the availability of host trees.

Australia has pioneered cultivation of Indian sandalwood as a commercial agroforestry crop. Sustainable Indian sandalwood plantations were established over 20 years ago, with now over 5.5 million Indian sandalwood trees growing across 12,000 hectares of land in northern tropical Australia.

First written information about sandalwood appears in Yasaka Nirukta a 500BCE Sanskrit literature on Hinduism. Thereafter, Indian sandalwood was mentioned in religious and romantic literature until the present day. By the 300 BCE, Indian sandalwood was recorded as a good to be taxed by the state as recorded on the Arthashashathra , the Indian treatise of economics and administration. Sandalwood was introduced to China during the Tang dynasty, since then it has played an important role in Chinese culture, making it among the most valuable imports to the empire. Medicinal properties of Indian sandalwood appeared in every treatise and Materia Medica in Ayurveda and Traditional Chinese Medicine. Legendary references of sandalwood use by Queen Cleopatra has been mentioned, however, Queen Elizabeth II and Queen Marie Antoinette have reported tohave used sandalwood in perfumery and beauty regime.

As the demand and the value of sandalwood increased Sultan of Mysore Kingdom has declared Sandalwood as the Royal tree in 1796. Widespread poaching of the valuable heartwood in the wild for over decades has led Indian sandalwood to reach extinction and listed on IUCN red list.


The Science of Indian Sandalwood Oil

Indian sandalwood oil is composed of over 125 constituents, from which two main sesquiterpene alcohols alpha and beta santalols make the around 80% of the composition and give the unique sandalwood aroma. Although beta santalol is half the volume component of its alpha isomer, it has a higher odour threshold and produces the warm, woody, sweet and lactonic notes of sandalwood.

While the base characteristics of sandalwood aroma come from the two main components, it is the minor components which give the subtle nuances unique to natural Indian sandalwood. Some of these constituents are synthesised by the tree parallel to santalols, but others are products of processing and distillation. It was identified that human nasal epithelium and skin keratinocytes have a specific odour receptor known as 2AT4, which is triggered by the santalol molecules to trigger the brain to recognise aroma as well as act on human skin and hair follicles.

Indian sandalwood oil has been identified for its remarkable antioxidant and anti-inflammatory properties on skin both in-vitro and clinical studies. Psychopharmacological studies have found that the Indian sandalwood oil is to decouple the brain’s central and autonomic nervous system activities to produce attentiveness while calming the body. There are several in-vitro studies conducted on anticancer and anticholinesterase activities of Indian sandalwood oil, which can benefit the human health immensely.

Chemistry and bioactivities of sandalwood has been extensively studied, yet there are many unknown properties of this mysterious tree to be uncovered.
