They are members of the same family as walnuts (Juglandaceae), although that doesn’t necessarily mean that they have the same chemical properties.

Think about the Solanaceae family. Edible plants like tomatoes, eggplants, peppers, and potatoes, and the highly toxic deadly nightshade, are all in the same family.

And there is a reason to be technical.
Focus on the quinone in that name. Quinone is a highly reactive compound that can be dangerous in the presence of oxygen.
So dangerous, in fact, that small amounts can kill a person.
