Dr. Edward Bach's story has been told many times, so I'll just give a brief synopsis. He was an English doctor (M.B., B.S., M.R.C.S., L.R.C.P., D.P.H.) who became disillusioned with traditional medicines, so he left his lucrative practice to find another way of healing. During the 1930's he discovered that the dew drops of certain plants had an effect on certain emotions.
He believed that all dis-ease began in the mind, and by healing the emotion that caused the dis-ease, you would also heal the illness itself by removing the cause.
From all accounts, he certainly was a remarkable, humble man, who would have endured much suffering in order to find all the remedies. This would have meant going through all the state of minds in order to find the cure.
"Treat the patient, not the dis-ease." - Dr. Edward Bach.
