Ananda has added a very in-depth discussion of the 12-7-19 method of Bach flower essence classification. The article begins with a look at how flower essence therapy works, and follows with defining the 12-7-19 method of classification developed by Dr. Edward Bach. Finally, the 'Twelve Healers' are examined; it is these flower essences that Dr. Bach indicated for the primary personality types he had defined. Part II and III of the article will examine the 7 Helpers and the Second 19, with brief descriptions of each essence. Enjoy!
