Plant of the week with Alexander McCowan

One of the oldest perfumes known to man

Sandalwood (Santalum album) is a tree of the Santalaceae family, growing to about 18m in well drained soil in forests in south west Asia. It is a slow-growing semi-parasitic evergreen tree with oval-shaped opposed leaves on slender, drooping stems terminating in pale yellow to purple flowers producing pea-size fruit that contains one seed. The bark is of a grey leathery consistency and holds two per cent of the oil. All parts of the tree yield an essential oil which has a very sweet balsamic aroma that has an excellent tenacity.

Sandalwood is one of the oldest perfumes; it has been known for at least 4,000 years, traces of it have been found in Egyptian tombs and it is recorded as a medicament in ancient Sanskrit tablets. The oil contains santalols, sesquiterpenes, santalone and borneol. In Chinese medicine, the oil is used to treat stomach cramps, gonorrhoea, choleraic difficulties, eczema and asthma. In the Ayurvedic tradition it is applied for urinary and respiratory infections and for chronic diarrhea.

Sandalwood has long been recognised in the west as antidepressant, antiseptic, astringent, aphrodisiac, bactericidal, carminative, fungicidal, insecticidal, cicatrisant, sedative and tonic. Aromatherapists have applied the oil to give relief in cases of acne, dry chapped skin, bronchitis, laryngitis, cystitis, depression, insomnia, nervous tension and stress.

The plant is a favoured building material in Hindu temples and is commonly used to manufacture ornamental boxes and to fuel funeral pyres throughout southern India.

Recent research indicates that sandalwood oil is effective against staphylococcus aureus, which is now becoming a scourge in many European hospitals. Some establishments are using a dilute solution of the oil to paint bed-frames and bedding material.

Sandalwood is extensively used as a component and fixative in soaps, detergents, cosmetics and perfumes, it is very popular in aftershaves. It is a major constituent in eastern religious incense, as well as prominently featuring in soft and alcoholic drinks.
