Natural 'Camphor/Eucalyptus' Smell As well as the anti-bacterial benefits of using Camphor Laurel as a food preparation surface is its natural 'camphor' smell. A little like eucalyptus, this natural smell WILL NOT PENETRATE OR CONTAMINATE YOUR FOOD but will help from keeping the board going 'rancid' after years of use. Once the smell diminishes from the board, a light sanding and a coat of grape-seed oil will restore the smell and luster to the board.
