Citrus x limon, also known as Citrus limonum and commonly known as Lemon, is a small evergreen tree that is a member of the Rutaceae botanical family.  The origins of the lemon seem to be shrouded in mystery.  Some sources suggest that it is thought to be a cross between a lime and a citron, though they do not necessarily agree on the specific species.  Others think that it is a hybrid of something else.  There are even those that believe it is not a separate species, but a descendant of another citrus.  To confuse things further, there does not seem to be a consensus on the definite place of origin.  Regardless of its origins, it is a popular citrus fruit that is known for its use in the food and flavor industry. 
 
Lemon essential oil has a fresh, lemony aroma that blends well with other citrus, fir, and wood oils.  It is commonly blended with other oils like Ginger and Peppermint for an invigorating aroma for long car rides.  Try diffusing with Lime, Douglas Fir, and Tea Tree for a clean, invigorating aroma to freshen the air.  Also, consider adding to a diffuser alone, or with oils such as Bergamot, Manderine, Wild Orange, and Lime, to create a cheery and uplifting environment.
 
Usage ideas:
Add a few drops of essential oils to a diffuser, cotton round, or a tissue.
Dilute to 1% in your choice of carrier oils to make a face serum or body oil.  Apply a small amount to damp skin after washing to help seal in moisture. 
Mix a few drops with an unscented liquid soap or bubble bath and add to the tub when filling. 
For convenience on the go…
Properly dilute with your choice of carrier oils in a roller bottle.
Add up to a total of 15 drops of essential oils to a personal aromatic inhaler (aroma stick).
