A tea made from the seeds is used in the treatment of asthma and bronchitis and is applied externally to wounds[222]. The pods are sedative and are thought to have cardioactive properties[222]. Distilled water made from the pods, mixed with eyebright (Euphrasia officinalis) and rue (Ruta graveolens) is a valuable eye lotion in the treatment of trachoma and conjunctivitis[7].

So, I would guess that the beans are not edible as such.
