In forty years of medical practice, I have found only two types of
non- pharmaceutical “therapy” to be vitally important for patients
with chronic neurological diseases: music and gardens.
I cannot say exactly how nature exerts its calming and organizing
effects on our brains, but I have seen in my patients the restorative
and healing powers of nature and gardens, even for those who are
deeply disabled neurologically. In many cases, gardens and nature
are more powerful than any medication . . . The effects of nature’s
qualities on health are not only spiritual and emotional but physical
and neurological. I have no doubt that they reflect deep changes in
the brain’s physiology, and perhaps even its structure.
