Maybe I've done a little too much research on this topic (but c'mon what's the interwebz for if not random information trolling?) but apparently women like lavender, patchouli, and licorice. Jasmine is equally attractive to men and women, and men like the smell of pumpkin pie and...donuts. Like these scents are physically arousing to men. Yes, inside every man is a Homer Simpson just waiting to bust out. And jasmine and Lavender really do help people sleep more soundly though.
And Aeon, yikes, thanks for the info.
There's actually all sorts of effects common household chemicals and items have on us. Like the plastics in everyday items like phones, kitchen cabinets, and even bottles degauss toxic fumes, soy is supposedly linked to cancer and messed up estrogen levels in boys (this is hotly contested, btw), and showering too much washes away precious pheromenes people need to bond.
With a lot of aromatherapy, from my own trial and error days, it's really about getting the 'purest' (or safest) distillations of the scents and using the proper carriers. Some essential oils are really strong and aren't meant to be put straight on the skin and you can also get food grade essential oils.
And Geoff, now you're sounding like TBGO!
But if we're gonna go there, supposedly women's breasts do naturally hold a higher concentration of bonding pheromenes than the rest of the body, but maybe that's only in lactating or pregnant women?
