Dr Bach provided very precise instructions on the making of the 38 flower essences. If these original instructions are followed to the letter, then any essence can legally be considered a Bach flower essence.
However, every plant and every individual is unique which means that no two brands are likely to produce identical flower essences.
This is why Healingherbs Bach flower essences are only made by Julian Barnard. Julian sources the flowers from carefully selected locations for every essence making. This ensures that there is total consistency in the quality of Healingherbs Bach flower essences.
Dr Bach also clearly stated that the essences should be preserved in brandy. So the organic French brandy which we use is compliant with the original directions. Other preservatives like glycerin are not as per original directions.
