A special blend of pure food grade mineral oil and natural bees wax make Emmet's Elixer the best moisturizer for your wooden boards and bowls. Both ingredients penetrate the wood to eliminate the natural expansion and contraction that occurs in wood products that often results in splitting. The addition of natural lemon and rosemary oil enables the wood to fight bacteria, giving you an additional level of protection. Emmet's Elixer is the only wood treatment to bear the NSF emblem, the highest standard that attests to product safety.
