Answer
The berries or seeds of *Ceanothus americanus* are specifically noted as not being considered edible.
While many parts of the *Ceanothus americanus* plant offer utility—leaves for beverages, roots for medicine, and flowers for soap—it is explicitly stated that consumption must be limited to certain preparations. It is critical to note that the berries or seeds produced by the plant are explicitly excluded from edible uses.
