Stripping the bark from old trees

The process of "extracting aromatic wood oil from the bark of old tree roots" refers to a traditional method of extracting fragrance components and essential oils from plant roots. Plants of the Lauraceae family (such as cinnamon and camphor trees) in particular contain strong aromatic components in the bark of their roots, and extraction has been practiced since ancient times. 1. Main plants from which aromatic oil is extracted Cinnamon: An evergreen tree of the Lauraceae family, the fragrance known as "nikki" is extracted from the bark of its roots. Camphor tree: The entire tree is fragrant, but "camphor oil" distilled from the roots and trunks of old trees is very famous. Ceylon cinnamon: An essential oil mainly composed of cinnamaldehyde is extracted from the bark and roots. 2. Extraction process Harvesting: The roots of fully grown old trees are dug up. Bark removal: The bark (root bark) on the surface of the roots is removed. This is where the most aromatic compounds are accumulated. Crushing and drying: To increase extraction efficiency, the removed bark is finely crushed and dried. Distillation (steam distillation): Steam is passed through the finely crushed raw material, and the volatile aromatic compounds are cooled to extract the oil (essential oil). Generally, it is classified as a type of "wood oil" or "essential oil" extracted from the wood and bark of trees.
