Camphor and Camphor Oil— Camphor is formed in the oil cells distributed in all parts of the tree. These cells are filled with clear yellow oil from which camphor is slowly deposited. The oil progressively becomes colourless and volatile, and irregular light masses of camphor appear. Due to loss of resistance to permeability, the oil passes through the cell walls into other cavities in the tissues. Camphor can be distilled from all parts of the tree i.e., from chips of wood, stem, root, branches, twigs and leaves (even from fallen leaves).
