Really? Woodlore websites says: Composition Aromatic cedar is made up of white and red sections of wood. The white section is referred to as sapwood. The red wood is called heartwood, as it contains the aromatic oils. Woodlore products include at least 75% heartwood for the greatest aromatic benefit. After one year, a light sanding with a medium sandpaper restores the aromatic properties. Benefits Cedar shoe trees, hangers, blocks and shapes play a vital role in protecting fine shoes and clothing. Aromatic cedar helps to repel moths and other insects. Because we don't coat our cedar with varnishes or lacquers, our all-natural shoe trees absorb moisture from footwear. Aromatic cedar also deodorizes with a forest-fresh scent.
