Essences are made for the purpose of correcting out-of-balance mental and emotional states. Each bottle of essence (unless otherwise stated) holds a 50/50% combination of Scottish organic spring water containing the subtle signature of the gem/flower it has been exposed to, and French brandy - that acts as a fixative and preservative. The healing powers of flower essences was rediscovered by Dr. Edward Bach in the 1930s. His work was based on Paracelsus' 16th century development of the doctrine of signatures.
Paracelsus' belief was that "Nature marks each growth... according to its curative benefit."
To make a flower essence, flower heads are immersed in spring water, and placed in sunshine for up to three hours. The subtle signature of what makes those particular flowers different from another flower species is then said to be held within the water molecules. The action of the sun's heat upon the water causes the hydrogen and oxygen bonds within it to temporarily separate. The flowers are then removed from the water and alcohol is added as a preservative and to fix the plant's subtle vibration within the water. A few drops of this mother essence are added to a 15ml bottle of water with alcohol to make a stock essence for sale to customers.
More recently, Dr. Masaru Emoto has demonstrated, through photographing ice crystals, that water carries the vibrations of anything that is put in contact with it, from flowers, gems and essential oils, to sounds and the surrounding environment.
