Rosemary

"Its (Rosemary's) scent can protect the brain from free radicals, which can cause dementia." Prevention Magazine March 2012 page 134

Scent can be powerful in its effects on the body and memory.  A scent can take a person back to a memory very quickly.  I remember the first time as an adult I smelled udder balm (which Dwane used on his chapped hands), I was taken instantly to the memories and setting of my father's dairy barn.  Similarly, scents can help us sleep (lavender), improve our mood (rose), and help protect us from dementia.  As caregivers for someone with dementia, we need to be vigilant to not let this disease take us along with it.  Growing rosemary indoors is one easy preventative.
