Crosshairs: Yes, I undersood your post to be humorous. It just got me thinking, which is probably a bad idea on a Friday. No oil is going to make anyone feel like doing something positive, that's for sure. Just look at what hash oil and opium do to people.
I wasn't saying aromas have no effect - Of course they do, like any chemical you expose your body to repeatedly: Habituation, aversion, possibly allergic reactions, etc. They just don't have the MAGICAL effects attributed to them by the quacks who promote "aromatherapy".
I have a particular distaste for patchoulli oil. That and the music of Al Stewart remind me of a b1tch who was my girlfriend for a couple of years back in the '70s. I also remember the perfume worn by a cranky mean old bat of a 6th grade teacher I had in Alamogordo, NM. It's that "old lady" smell. And that HORRIBLE strawberry stuff some girls wore in about 1968. Now that was enough to put anyone off of any kind of food.
Smells carry too much baggage. I don't know how animals like dogs can stand it. Supposedly stuff that turns our stomachs is usually just another smell to a dog.
