Virtues of Sandalwood Extend Through Time

By Sandra O'Ryan

Overview

Sandalwood is one of the oldest aromatic materials, being acknowledged in ancient biblical and in Indian text as well as used in religious ceremonies throughout the ages. Botanically known as a small evergreen in the genus Santalum and family Santalaceae, this modest-sized tree (up to 10 meters) provides a great deal of commerce for India and to some extent Australia and is now being examined by the medical industry for its medicinal properties. There are several species of Santalum, but only a few are used commercially, most notably Santalum album (India) and Santalum spicatum (Australia). Other tress from such places as Polynesia and Fuji are in small numbers and in great decline. Oddly, other plants such as the Bead Tree or Candlewood are known as sandalwood but are not botanically parallel. Sometimes, non-related plants such as Red Sandalwood are used as fillers for the more expensive, genuine sandalwood.

Sandalwood from the Mysore region (known as "sandalwood city") of southern India is generally considered to be of the highest quality sandalwood available, providing great commerce for this region of India. Of the traditional areas in Southeast Asia where sandalwood is found, India has been the front runner in creating plantations in which to continually harvest Sandalwood (The Australian Government has also set up reserves as well). Trade and harvest of Indian sandalwood is under strict regulation and the trees themselves are under government protection; only the government of India is permitted to own the trees. To produce commercially valuable sandalwood with high levels of fragrance oils, harvested Santalum trees are recommended to be at least 40 years of age, but 80 or above are preferred. However, trees at 30 years of age are still harvested but considered of inferior quality.

In order to retain valuable wood and oil found in the larger roots, trees are felled by uprooting, not cutting the truck. Unfortunately, many trees are illegally cut down and smuggled out of the country. In the last five years alone, the price of sandalwood oil has skyrocketed. This is mainly due to increased demand from the aromatherapy and cosmetic industry. The oil is revered by the perfume industry as being an excellent base and fixative for other high grade perfumes. The industry finds that sandalwood oil can blend well with other perfumes and when used as a base does not impart its own fragrance, thus making it a very popular ingredient for hundreds of perfume products.

Such value is found not only in its iconic-making wood, medicinal oil and fragrance but also in it religious and ceremonial value. In the Buddhist tradition, sandalwood incense is a popular offering to the Buddha and its scent is believed to have transformative qualities while in meditation. Chinese and Japanese religions also use sandalwood incense in their worship and various ceremonies. One of the oldest religions, Zoroastrianism (thought to be originally from Iran), burns the sandalwood in their sacred fire temples.

Sandalwood Used to Fight Anti-microbial Bacteria

Opposition to antibiotic use in food agriculture has been gaining momentum. In years past, it was known that severe illness-causing microbes such as Salmonella and E. coli could be contracted through eating contaminated meat. Now, it is proposed that contraction of bacteria, in this case antibiotic resistant bacteria, can possibly be transferred through ingestion, handling of industrial animal manure, as well as through drinking manure-contaminated ground water. With these scenarios coming to the surface, scientists and government officials alike are in alarm and strongly suggesting the decrease if not absolute elimination of non-therapeutic uses of antibiotics in the meat industry. Recent media has brought attention to the proposed link between the steep increase of antibiotic-resistant microbes with use and perhaps misuse of antibiotics in agriculture. Modern industrial agriculture raises animals in tight often inhumane quarters which results in animals being much more susceptible to sickness and disease, thus the administration of antibiotics is very common. Because bacteria and other microbes can easily mutate (in as little as 20 minutes), it is no wonder that great concern is now mounting.

Concern for antibiotic-resistant microbes is worldwide. A need to find alternatives to conventional antibiotic treatment is rising. Essential oils have been gaining attention by research scientists for their antimicrobial properties. A collaborative study of researchers in Austria and Germany (Flavor and Fragrance Journal 2006 May/Jun; 21(3): 465-468) found that santalols of sandalwood (the main chemical components of sandalwood) in medium and/or high concentrations showed significant antimicrobial potential against the yeast Candida albicans, the Gram-positive bacterium Staphylococcus aureus, and the Gram-negative bacteria Escherichia coli, Pseudomonas aeruginosa and Klebsiella pneumoniae.

Uses Beyond Bacterial

The Australian and Indian Santalum species, found to be similar in chemical composition, are known by aromatherapists to have such therapeutic properties as anti-inflammatory, antiphlogistic (reduces fever), antiseptic (as mentioned above), antispasmodic (relieves muscle spasms), astringent, carminative (relieves flatulence), demulcent (reduces irritation), diuretic (soft and soothing to skin), emollient, expectorant, as a sedative and general tonic. Their principle chemical constituents are alpha-santalol and beta-santalol. According to a study conducted by the Department of Pharmaceutical Sciences and South Dakota University (Anticancer Research 2007 Jul-Aug; 27(4B): 2185-8) application of the chemical compound alpha-santalol prevents UVB-induced skin tumor development in mice. Sandalwood is also thought to help alleviate the symptoms of depression as reported by the University of Maryland Medical Center (www.umm.edu).

Summing It Up

Since ancient times humankind has relied upon plants for their nutrition, their health and for other therapeutic uses that enrich their way of being. Today is no different. It is evident that in modern times, conventional overuse of antibiotics and pesticides has resulted in harm to humankind and the environment. As more information is brought to light about antimicrobial resistant bacteria and other harmful microorganisms, medical scientists will be diligently searching for alternative solutions. The science studies published thus far indicate that research into alternative treatments, including the use of sandalwood essential oil, to remedy this problem is increasing. It is hopeful that sandalwood and other essential oils will be incorporated into medical healthcare and perhaps awaken the larger populous about the importance of living simply and in partnership with the earth. - 14130
