Home Herbal Monograph Deodar, Himalayan Cedar, True Cedar
History

This was an important tree species in north India for domestic and also for commercial appliances. Its wood was as good as sal and teak. Oil was distilled from the waste wood and from woodcarvings in earlier periods, which was useful in relieving pains and rheumatic complaints. Oil was useful for skin complaints including mange in horses in ancient times. In a 20 per cent concentration made in castor oil, it produced 100 per cent curative effect against sarcoptic mange in buffalo-calves. It was also used effectively against sarcoptic mange in dog, sheep, goat and camel.

It is found throughout the western Himalayas from Afghanistan to Garhwal, at elevations ranging from 1,200 m to 3,000 m above the sea level. It is most common from 1,800 m to 2,600 m. In India deodar forests are common from Kashmir to Garhwal and form the bulk of the vegetation in these regions.
