Is it possible to choose Dr. Bach Flower Remedies according to their positive potential?

This has not been seen to be effective.

The positive potentials of the Flowers are ideal aspects of the divine nature of humanity.

This is a collective unity and contains all the potentials in an undifferentiated state. The negative behavior patterns are distortions that have become separated from the whole and can therefore be observed, described, and diagnosed precisely in their separate expressions.
