Hornbeam is used against feelings of exhaustion and tiredness that come before an effort has been made.
The person in this state feels that he or she is too tired to cope with the demands of the day. It's easier to stay in bed or put off making a start - but if an effort can be made to get started the weariness will fade, a sign that unlike the Olive state this is a mental rather than a physical weariness.
Dr Bach's description - For those who feel that they have not sufficient strength, mentally or physically, to carry the burden of life placed upon them; the affairs of every day seem too much for them to accomplish, though they generally succeed in fulfilling their task. For those who believe that some part, of mind or body, needs to be strengthened before they can easily fulfil their work.
