Oak... ...is the remedy for strong, steady people who never give up under adversity. Instead they plod on with determination, and never consider resting until they are past the point of exhaustion. Because they are so steady they often have many people relying on them, and their sense of duty is strong, so that they can feel frustrated and unhappy if illness or exhaustion get in the way of discharging duties. So much is positive about the Oak person, but the negative side is the stubborn refusal to rest or sit back when the need for rest is obvious to all around.
The remedy is used to help the Oak remain strong in adversity and not crack under the strain, while at the same time a different wisdom is learned, so that the person in this state can learn when not to strive.
Dr Bach's description - For those who are struggling and fighting strongly to get well, or in connection with the affairs of their daily life. They will go on trying one thing after another, though their case may seem hopeless. They will fight on. They are discontented with themselves if illness interferes with their duties or helping others. They are brave people, fighting against great difficulties, without loss of hope or effort.
