Sandelhout 
Sandeltræ Sandalwood is a tree that can get up to 9 m high. It is used in Asia for building temples and making furniture, and of course for incense. Essential oil is distilled from the wood of the tree as well. The older the tree, the better the oil; a minimum of 30 years is normally required. The oil is obtained by water or steam distillation. It has a dark yellow colour and is very thick.
The best essential oil comes from Mysore. It is distilled from the roots and the heartwood. It is a sweet, warm, harmonizing oil, very good in perfumes and skin products.
The heartwood sold for incense is yellowish in colour, and has a characteristic fragrant odour.
Red Sandalwood is an entirely different species, Pterocarpus santalus or sometimes referred to as Santalum rubrum, although it is not related to S. album. It is often called Red Sanderswood. It does not have the scent of the white sandalwood. It is used solely for colouring purposes. In a recipe, you cannot substitute Red Sandalwood for White Sandalwood. The Red Sandalwood can, however, be used as a neutral base in incense recipes.
As to White Sandalwood's magical properties, Beyerl states: "It carries the virtue of success with it", and Druehyld also recommends it when embarking on new projects. Cunningham says it has "very high spiritual vibrations". The correspondances differ a lot; again, you better trust your own feeling rather than copying from a book.
Sandalwood oil blends well with:
