Fragrance from the Forest

Have you ever spent time outside in nature and discovered that the scent of nature brought back a memory?

Plant fragrances play a significant, yet often subtle, role in our appreciation of the outdoors. While roots and bark emit some aromas, most fragrance is found in plant flowers and leaves (e.g. eucalypts) and might be released into the atmosphere on hot days or with heavy rain (Elliot 1996).

It is not so much for its beauty that the forest makes a claim upon men’s hearts, as for that subtle something, that quality of air that emanation from old trees, that so wonderfully changes and renews a weary spirit.” ~ Robert Louis Stevenson

Our weary spirit caused, in part by “techno-stress” and urbanization, has led to a society which is stressed and disconnected from the soothing effects of nature (Miyazaki et al. 2014) also known as Vitamin N (Louv 2016). Nature reconnection practices, which encourage improved lifestyle choices and better mental health in urbanized societies, include, but are not limited to, forest therapy, wilderness therapy and outdoor meditation (Liebeck 2016) and address the mental, physical, emotional, social, spiritual and environmental factors of human wellbeing (Pierce 2010).

Forest Therapy, under the umbrella of nature or ecotherapy has existed in Japan since the Forest Agency of Japan promoted Shinrin-yoku (“forest bathing” or “luxuriating in the forest atmosphere”) as a practice for healthy living and part of a “forest therapy” program (Ikei 2014).

Forests often deliver large amounts of olfactory-provoking chemicals, identified as phytoncides. Phytoncides are secondary metabolites produced by plants (such as cypress) and are closely related to essential oils (Li et al. 2006) which are likely to have a number of functions in plants including defense, helping with pollination, protection, allelopathy and antitranspirant activity.

A guided Forest Therapy walk is likely to include natural aromatherapy and the inhalation of phytoncides. Inhalation of phytoncides consisting of tree antimicrobial volatile organic compounds such as α-pinene (which is found in eucalypts) and limonene (Li et al. 2006 and Halter 2018) can contribute to decreased stress, balance mental outlook (Selhub & Logan 2012) and improve immunity (Li et al. 2006).

When next you are outdoors bathe in the fragrance of the trees and in addition, follow these 10 nature-inspired practices to de-stress.

The fragrance with which one is feasted in the woods is, like music, derived from a thousand untraceable sources…the whole air vibrates with myriad voices blended that we cannot analyze. So also we breathe the fragrant violets, the rosiny pine and spicy fir, the rich invigorating aroma of plushy bogs in which a thousand herbs are soaked …” ~ John Muir
