What is cedar wood?
Cedar, from the genus Cedrus, is an evergreen conifer within the Pinaceae family, originating from the mountainous regions of the Mediterranean, including the Atlas and Himalayas, but it can also be found in North America. In the Himalayas, cedars thrive at altitudes between 1,500 and 4,000 meters, while in the Mediterranean, they are found at elevations of 1,200 to 2,200 meters.
Cedars grow at a moderate rate of about 25 inches annually and hold significant economic and cultural value. Among the various cedar species, the Eastern red cedar (Juniperus virginiana) and the Western red cedar (Thuja plicata) are particularly valued.
The Eastern red cedar is characterized by its reddish-brown heartwood and paler yellow sapwood, with a mildly resinous fragrance. The Western red cedar, on the other hand, typically displays a reddish to pinkish brown hue in its heartwood with yellowish sapwood and emits a stronger, more distinctly cedar aroma. Both species feature a straight grain pattern, although the texture of the Western red cedar is generally coarser.
Cedar wood properties
Cedar wood has been utilized in a plethora of ways throughout history, ranging from its mention as a type of incense in the Bible, known as the cedar of Lebanon, to contemporary applications like linings for cedar chests, pencil and paper production, fence posts, shingles, and shakes.

Cedar wood as a cutting board material
Cedar wood, with its distinct properties, might seem like an attractive option for crafting cutting boards due to several beneficial attributes. However, there are significant drawbacks that need consideration before choosing it for such a purpose. Here’s a detailed look at the pros and cons of using cedar wood as a cutting board material:
Pros
- Antimicrobial Properties: Cedar wood naturally possesses antibacterial and antifungal qualities, which can help inhibit the growth of bacteria, making it a hygienic choice.
- Aesthetic Appeal: The unique reddish-brown heartwood and lighter sapwood of cedar offer a visually appealing contrast that isn’t typically found in other woods used for cutting boards.
- Resistance to Rot: Due to its inherent resistance to decay, cedar is well-suited for environments exposed to moisture, which is a common condition for cutting boards.
Cons
- Softness: Cedar wood is softer than ideal cutting board materials, with a Janka hardness rating of only 350 lbf for Western red cedar and 900 lbf for Eastern red cedar. These values fall short of the optimal range (900 to 1500 lbf) for cutting board woods, which includes hardwoods like maple and walnut. This softness results in a surface that is easily marked by knives, leading to dents and scratches that are not only unsightly but also make cleaning more challenging.
- Brittleness: Cedar’s lower hardness and strength increase its likelihood of splitting or cracking, particularly under frequent use or accidental impacts.
- Toxic Oils: The natural oils in cedar, which are toxic to insects and used as a moth repellent, could potentially leach into food placed on the cutting board. These oils contain compounds like thujic acid and pinene, which, in higher concentrations, could pose health risks, such as respiratory issues or skin irritation.
- Tannin Stains: Cedar wood contains tannins that can bond with proteins and carbohydrates to create tan-coloured stains, which might also stain your hands during use. This can be an inconvenience when using the wood for kitchen applications.
- Lingering Odor: While cedar’s aroma is often considered pleasant, it can be overpowering in a kitchen setting. The scent might permeate food items, altering their taste and potentially detracting from the culinary experience.
The Dilemma of Cedar as Cutting Boards
Indeed, cedar wood’s natural resistance to decay and rot might initially suggest it as an excellent candidate for cutting boards. However, the situation is nuanced and reveals why it might not be the best choice for this purpose.
While cedar’s rot-resistant qualities are beneficial, its classification as a softwood reveals a critical drawback for cutting board use—it lacks durability. The soft nature of cedar means it is prone to damage from everyday kitchen use, especially from cutting and chopping. This results in the wood surface developing grooves and cuts more quickly than hardwoods.
These imperfections in the wood are not just aesthetic concerns. They can become harbours for bacteria and other contaminants, potentially leading to foodborne illnesses. Once these grooves form, they can be difficult to thoroughly clean and sanitise, making the board less safe over time.
In contrast, hardwoods like maple, walnut, and bamboo offer greater durability, which means they do not easily succumb to knife marks. Their denser and harder surfaces make them less likely to develop deep cuts that can harbor harmful bacteria. For these reasons, hardwoods are generally preferred for cutting boards in both residential and professional kitchens. They provide a balance of durability and safety, ensuring a longer-lasting, more hygienic surface for food preparation.
How to Make Cedar Food-Safe
If you’re set on using cedar for a cutting board due to its aesthetic appeal or other qualities, there are steps you can take to mitigate some of its drawbacks. Properly sealing the wood is crucial to making it more suitable and safer for use as a cutting board.
Steps to Properly Seal Cedar for Cutting Board Use:
- Choose the Right Sealant: Select a food-safe sealant that is specifically designed for use on cutting boards. These sealants should provide a durable, hard finish that resists knife cuts. Options include food-grade mineral oil, beeswax, or a combination of both. Avoid common furniture finishes and cooking oils, as these can become rancid or are not durable enough for cutting board use.
- Prepare the Wood: Before applying any sealant, ensure the cedar surface is smooth and clean. Sand the wood with fine-grit sandpaper to remove any rough patches or previous finishes that might interfere with the sealing process. Wipe down the surface with a damp cloth to remove any dust.
- Apply the Sealant: Apply the chosen sealant according to the manufacturer’s instructions. For mineral oil, apply a generous amount to the surface of the wood and use a clean cloth to spread it evenly. Allow the oil to soak into the wood for several hours or overnight. For beeswax, you might need to melt the wax and mix it with the oil before application.
- Buff the Surface: Once the oil has soaked in, wipe off any excess with a clean cloth. If using a beeswax mixture, buff the surface to a smooth finish. This step helps to create a barrier that moisture and bacteria cannot easily penetrate.
- Maintain Regularly: Regular maintenance is key to keeping a cedar cutting board safe and functional. Reapply the sealant every few months or more frequently if the board sees heavy use. Always clean the board thoroughly after use and dry it completely to prevent water damage.
- Monitor for Damage: Regularly inspect the cutting board for deep cuts, grooves, or any other damage. If significant damage occurs, it may be necessary to re-sand the surface and reapply the sealant to maintain its protective layer.
Why Cedar Cutting Boards Are Toxic to Humans?
Toxicity and Aromatic Oils
Cedar wood contains aromatic oils and compounds such as thujone, which are naturally toxic to insects. While these oils help the tree crown survive by repelling pests, they can be problematic when the wood is used for cutting boards. The continuous contact with food can lead to these compounds leaching into food, potentially causing digestive issues like vomiting and nausea, as well as respiratory problems such as a runny nose and asthma.
Softness and Durability
Cedar is a softwood with relatively low stiffness, strength, and hardness compared to hardwoods like maple, commonly used for cutting boards. Here are some numerical values to illustrate cedar’s softness:
