The effects of flower essences were first discovered in 1934 by an English homeopathic physician and bacteriologist, Edward Bach. Since then, hundreds of new essences with properties similar to the original 38 Bach flowers have been discovered. Flower essences are highly effective and safe to use. The effects of flower essences include changes in attitude, renewed motivation, enhanced personal growth, and expression. However, they cannot substitute for a true change of heart and attitude, which occurs by personal choice and belief.
