Lemon
I like this therapy roll on.  The smell is great and despite not having any lemon oil it smells like lemon to me (Grapefruit and lime bergamot are the citrus scents in this plus a fir and peppermint).  I tried it out when I had a slight migraine and it didn't help but it also didn't make it worse.  I don't think it was designed for headaches so I'm going to give it a go on a non headache day and see if it helps with mood and alertness.  I like the smell a lot and expect it will help somewhat with mood improvement.
