of stamps produced by Australia Post. It is well known as an exotic food in foreign markets, sales that greatly exceed the consumption in its own country. The fruit also has free radical-scavenging ability. The fruit has been made commercially available, the distinctive flavour is used as an additive, particularly as a uniquely Australian product. This has usually been sourced from wild trees, sometimes by Aboriginal corporations, although the viability of commercial orchards is also being trialled. Many Aboriginal peoples are known to have used the fruit, but mainly they gathered the nuts. The undigested nut can be easily gathered from emu droppings. The kernel has been identified, analysed, and monitored, as a "wild-harvested Australian indigenous food", by Food Standards Australia New Zealand. The product is found to be very high in fats, over half by weight. Medicinal use The fruit, containing vitamin C, and the kernel of the nut, containing complex oils, were used by the peoples in whose countries the species occurred. Antibacterial qualities are present in the wood of this, and all the Santalum species, especially in the roots. A known application of the extract was to heal ailments of the skin. The commercial production of cogenor S. spicatum is more advanced than this species, although research is being undertaken into the marketing of these medicinal substances. Fuel The seed is very high in flammable oils, like a candlenut, so it is able to be burnt as an illuminant. The wood is also oily, useful for starting a fire as a friction stick. Timber The hard, oily, timber is used for furniture and cabinet making by regional craftsmen, but it is not used extensively. It is a durable material, but lacks the aromatic qualities of other sandalwoods. The hard and wrinkled nuts have been used ornamentally, for necklaces and shirt buttons, and were used as marbles on chinese checkers' boards. History The oil of sandalwoods, primarily Santalum album, was described and investigated by pharmacologists. The more widely known Australian sandalwood, S. spicatum, was extensively harvested and exported, leaving S. acuminatum as the more common Santalum in many regions. The established use of the fruit, by Aboriginal peoples, was acknowledged by the early settlers of the colonies; this product was made into jam and chutney. The fruit is frequently mentioned in natural histories and botanical works, such as Flowers and plants of Western Australia, and traded as a
