When i was working on a project in Tunisia, i saw lots of the locals walking around in the morning with little sprigs of rosemary (which grows everywhere there) and taking sniffs of it as they commuted. When I asked about it, they mentioned it was like a morning coffee, they felt it woke them up, and "got their brain firing". I gave it a go, and (n=1) it definitely felt like a pick me up. I grow rosemary in my garden now, and every morning as I am getting ready for work I will grab a bit and smell away.
