...is the remedy for strong, steady people who never give up under adversity. They plough on with determination, and never consider resting until they are past the point of exhaustion.
Oaks often have many people relying on them, and their sense of duty is strong. They may feel frustrated and unhappy if illness or exhaustion mean they are forced to do less than they wanted.
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. The remedy is used to help us remain strong in adversity, while at the same time we learn it is better sometimes to let go rather than crack under the strain.
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.
