Sandarac

Sandarac

In mineralogy, sandarac, or sandarach, may refer to realgar or native arsenic disulfide, but is generally (a use found in Dioscorides) a resin obtained from the small coniferous tree "Tetraclinis articulata", native to the northwest of Africa, and especially characteristic of the Atlas mountains. The resin, which is procured as a natural exudation on the stems, and also obtained by making incisions in the bark of the trees, comes into commerce in the form of small round balls or elongated tears, transparent, and having a delicate yellow tinge. It is a little harder than mastic, for which it is sometimes substituted. It is also used as incense, and by the Arabs medicinally as a remedy for diarrhea. It has no medicinal advantages over many of the resins employed in modern therapeutics. A similar resin is produced in China from cypresses, and in southern Australia, under the name of pine gum, from "Callitris preissii".

Sandarac is also the common name of several types of tree:

* Tetraclinis
* Citronwood, used in building the roof of Cordoba cathedral
