Quercus robur Keywords: Exhausted but struggles on Oak people are normally brave, strong and reliable; they need Oak when their inner strength wanes and fatigue takes over. They keep going, whatever happens, ignoring their tiredness. Driven by a strong sense of duty, they are helpful to others, conscientious and reliable. They are patient, sometimes plodding, and will not allow themselves to relax if there is work to be done; instead they struggle on obstinately when over-tired (see also Rock Water and Vervain).
