Wood Toxicity and Allergen Chart

You will find below a chart of several varieties of wood species, accompanied by their reported properties and effects. You will note that the information on the chart was gathered from several sources When viewing the chart, please keep the following in mind:

If a wood is not listed on the chart, do not ensure it is fully safe to use.

If you don’t see a certain wood on the chart, it should not lead you to the conclusion that it is entirely safe to use. It just means that any adverse reactions have not been reported as of the printing o this chart. (It is possible that the wood is obscure or unknown.) It is helpful, if you have been positively diagnosed that you are indeed allergic to a certain species of wood, to take the time to research related species of woods There are many times that a wood in a certain genus will share similar allergy complexes with other related woods. This can result in cross reactions.

All types of wood dust that are inahaled are hazardous to your health.

Any type of wood dust can be extremely hazardous to your long term health. This chart merely pointsout the specific woods that will aggravate symptoms through an allergic reation, or a wood that is simply outright toxic. Keep in mind that ALL woods will produce a fine dust when they are worked. This dust will in turn damage your lungs and can create a series of other adverse health issues as well.

What types of wood are safe to use as cooking or dining ware?

In spite of the extensive list of woods that you see below, there are very few woods that are toxic in and of themselves. What the problem becomes is that the woods have the potential to cause allergic reactions in sensitive people. The risk is greatly reduced, but not completely eliminated, with the application of a food safe finish. In the end, keep in mind, that using any type of wood can be a calculated risk. The question boils down to this, “How much of a risk am I willing to take?”
