Pterocarpus santalinus

Timber

The wood has historically been valued in China, particularly during the Qing dynasty periods, and is referred to in Chinese as zitan (紫檀) and spelt tzu-t'an by earlier western authors such as Gustav Ecke, who introduced classical Chinese hardwood furniture to the west.^[6] An exquisite chair made of red sandalwood can be seen today in China's Forbidden City in Beijing, inside the Hall of Supreme Harmony, and once used by the emperors of the Qing dynasty.

Due to its slow growth and rarity, furniture made from zitan is difficult to find and can be expensive.^[7] It has been one of the most prized woods for millennia.

In India red sandalwood is one main and lucrative market for smugglers, as a high price is paid for this wood in China. Since the exporting of sandalwood is illegal in India, the underground market is growing and there are a number of arrests every year of those trying to smuggle this wood to China.^{[citation needed]}

The other form of zitan is from the species Dalbergia louvelii, Dalbergia maritima, and Dalbergia normandii, all similar species named in trade as bois de rose or violet rosewood which when cut are bright crimson purple changing to dark purple again. It has a fragrant scent when worked.^[6]

Shamisen

Red sandalwood has been used for making the bridge and also the neck of the Japanese musical instrument shamisen.^[8] The heartwood is preferred for this purpose.^{[citation needed]}

Medicinal values

Pterocarpus santalinus is used in traditional herbal medicine as an antipyretic, anti-inflammatory, anthelmintic, tonic, hemorrhage, dysentery, aphrodisiac, anti-hyperglycaemic and diaphoretic.^[9][10]

Grading of red sandalwood

Red sandalwood grown on the shale subsoils, at altitudes around 750 metres (2,460 ft), and in semi-arid climatic conditions gives a distinctive wavy grain margin. Lumber pieces with the wavy grain margin are graded as "A" grade. Red sandalwood with wavy grain margins sells at higher prices than the standard wood.^{[citation needed]}
