Fads are always changing, and ideas that are always combating one another. Some ideas that are combative, although often used in conjunction with, aromatherapy are:
Music Therapy: Some people say that music therapy, though not as well established as aromatherapy, works better at soothing the psyche and can even have physiological effects. Often used for relaxation, music therapy can also be used to boost energy and productivity (in a work place).
Meditation: Some people say that meditation really helps to focus the mind, become more in tuned with yourself and to help relax, and help productivity.

Other possibilities include decorating according to Feng Shui beliefs or Vastu beliefs. Also recomended is to decorate according to color theory.
