Amid the noisy coverage of high-cost health care and high-tech medicine, one inexpensive, low-tech therapy has received scant attention — horticultural therapy. This approach has proven an effective adjunct therapy for a broad range of conditions.

This is no revolutionary therapy. In Ancient Greece, the first healing places were gardens surrounded by rows of sleeping rooms where the sick would rest after tending to the plants and bathing in nearby streams. Set on farms, these early wellness gardens gave patients fresh vegetables and afforded them slow physical movements among colorful flowers.
Later, these became spa-gardens where advanced healers such as Hippocrates, the western world’s first doctor, extended care further with fresh medicinal herbs and even dream interpretation. He also insisted that the aristocracies in the local towns and cities allow rooms for both rich and poor — a paradise on Earth. No wonder gardens were the first hospitals.
In the U.S., Benjamin Rush, the country’s first surgeon general and a pioneer in the treatment of mental illness, was convinced that gardening speeded the recovery of asylum patients. Currently, there are more than 500 healing gardens at U.S. health facilities, and the number — you might say — will only grow.
Gardens represent a fresh horizon. The garden awakens the senses: visual, tactile, olfactory, kinesthetic. In tending a plant, a person is engaged with daylight, fresh air, water, earth, the seasons, the rising and setting of the sun — reconnected to the natural world.
Plants are egalitarian partners, providing a sense of purpose, self-reliance and accomplishment. As one tends the plant, the plant responds. Every bit of love is reflected in the plant’s health, beauty and productivity.
If this sounds touchy-feely, well, it most wonderfully is. But the fuzzy feelings inspired by horticulture are bolstered by a growing body of scientific research. The researchers’ findings substantiate green therapy’s extraordinary health benefits.
Thanks to biofeedback measurements, researchers know that, within minutes of stepping into a garden, a person experiences positive changes in stress level, heart rate, blood pressure and body temperature. Working with plants over time enhances mood, improves coordination and reduces pain awareness.

How can you explain these extraordinary results? Richard Mattson, professor of Horticultural Therapy at Kansas State, cites three factors:
* Over a few hundred million years, man co-evolved with plants developing a dynamic mutual relationship.
* Nurturing is an activity ingrained in who we are. The will and ability to bring a plant (or child) to life, nurture it into growth, and help it survive is an indispensable human endowment. In nurturing, we ourselves are nurtured.
* Plants radiate what Mattson terms a “halo effect.” The stored energy within the plant — the union of sunlight, air, and minerals — is felt and absorbed by humans. Just as we absorb the stored energy of plants we eat, we absorb energy when interacting with them.
Skeptics may scoff at such notions of plant energy and demand the data. But I feel sure that most home gardeners and patients engaged in plant therapy have first-hand knowledge of this “halo effect” — the glow when you grow.
