Loved this by Cathy Skipper:

Aromatic plant molecules are an important element in a Bio-Psycho-Social-Environmental-Spiritual approach to healing. They can be allies in deep personal transformation by reawakening the senses and reconnecting humans to the consciousness of the ecosystem they are merely a part of. If we allow ourselves to see our entire ecosystem as one system in which all the different participants, i.e. plants, animals and humans are in constant, mostly unconscious communication, then volatile aromatic molecules found in plants can be viewed analogous to neurotransmitters or neuro-hormones in this network that is larger than any individual or species. Aromatics reawaken the senses and awareness. They truly are the ‘molecules of connectedness.’
