Hazards

Most reports say that no member of this genus contains any toxins and that all have more or less edible leaves. However, one report says that if very large quantities are eaten they can cause photosensitivity [70]. If plants are grown with artificial fertilizers they may concentrate harmful amounts of nitrates in their leaves. [PFAF]
