According to Dr. Bach, the Flower Essences work by:
"raising the vibrations of the individual and opening the channels necessary for the reception of the Spiritual Self; to flood ones nature with the particular virtue needed and to wash out the fault which is causing the harm. They cure, not by attacking the disease, but by flooding the (subtle) body with the beautiful vibrations of one’s Higher Nature, in the process of which, disease melts away as snow in the sunshine. There is no true healing unless there is a change in outlook, peace of mind and inner happiness"
