Their aroma is very unique and cannot be replaced. At present, the cedar wood resources are dwindling; a serious influence had taken place in the flavor and fragrance industry. Study found that essential oil is very rich in fir wood waste; cedar wood oil can be replaced completely with the fir oil to be used in perfume industry according to the aroma and chemical composition. The fir oil was extracted from fir root and its processing residue by the steam distilling and retorting methods.
