Just like Walnut with its slight chance of a reaction for people with nut allergens, there is a very small chance for people to have some irritant issues with the Exotic woods. Plenty of domestic woods can cause similar irritant issues.
Wood workers are exposed to the woods in the form of sawdust, which is exponentially more than using a cutting board.
These woods are more porous than some of the domestic woods like Maple and therefore require more care. Use the board conditioner frequently to keep the board as water resistant as possible.
The board conditioner also helps prevent the wood from becoming dry and preventing splinters. This is needed for all woods but primarily Wenge which can be really sharp if the board is not maintained.
