Bach flowers are usually intended as final preparations deriving from the infusion, in water and alcohol, of specific flowers .

Bach’s flower remedies, based on flower therapy, are based on the thesis according to which at the base of a disease there is an energetic disorder, manifested by the appearance of symptoms.

Each physical disorder corresponds to a psychological or emotional disorder. The flower intervenes in curing moods and reactions to events, in the belief that the mind affects the natural well-being of the body.

Each flower or essence would correspond to a specific psychological state of the patient, expressed by several symptoms. There are 38 essences that are divided into healers , aids and assistants . To these is added the Rescue Remedy , Bach remedy n.39, with temporary stabilizing purposes in cases of psycho-emotional emergency. 

Edward Bach formulated the flower cure theory in stark contrast to the academic environment. Graduated in Medicine in 1912, he soon approached homeopathy and the conception according to which disease is the mirror of the patient’s personality. On this basis, he formulated his own theory, the components of which clearly draw inspiration from homeopathy , Ayurvedic medicine , Chinese herbal medicine, pranotherapy and reflexology .
