Archetypal Essences do not work on the emotional level but on the unconscious level.
They are not prescribed according to a patient’s emotional needs but to the needs of his weak archetype within. If a client is anxious, a Bach Flower therapist might prescribe  Mimulus to assist him to find access to his inner courage.  In Archetypal Flower Essence therapy, we look for a basic weakness of an archetype that causes the symptom of ‘anxiety’.
Such archetypes can be found in nature, too, and when we take the essence of the plant of the archetypal mother we strengthen the mother within ourselves. This is the idea behind the archetypal essences.
