Hi,
As the comments below point out, the compound you are looking for is
old fashioned "smelling salts," spirits of ammonia, Ammonium
carbonate, (NH3)2CO3·H2O.
It is commonly mixed with a perfume - often eucalyptus oil. Although a
1905 recipe calls for a solution of oil of nutmegs, oil of lemon and
dilute alcohol.

The standard method of administration is inhalant amoules. These are
small vials covered with a cloth. This remedy is standard in a well
stocked first aid kit. Break the vial and pass it in front of the
swooner or the sleeping person and the reaction is immediate.
Smelling salts work as a stimulant. "The ammonia fumes from the salts
irritate the membranes of the nose and lungs, which triggers a reflex
causing the muscles that control breathing to work faster."

http://www.bartleby.com/65/am/ammonia.html provides the The Columbia
Encyclopedia definition and some interesting facts about the history
of the compound. "Because ammonia was formerly obtained by destructive
distillation of horns and hooves of animals, its water solution was
called spirits of hartshorn."
http://www.inchem.org/documents/jecfa/jecmono/v17je02.htm has along
list of animal tests that give an overview of the side effects,
stating that it's pretty bland unless you really take a extreme
amount. The 1905 herbalist cited above has some pretty drastic side
effects including paralysis and coma. Another medical source from 1902
warns,"prolonged inhalation inducing violent inflammation and oedema
of the glottis."

Taking the normal amount available in an amoule, doesn't seem to
produce any adverse side effects.
The "Household Cyclopedia of General Information" published in 1881
uses "aromatic spirits of ammonia" in combination with other drugs to
treat epidemic cholera.

Another useful bit of trivia is that it can be used as a cure for the
hiccups!
"Mix two teaspoonsful of baking soda, two teaspoonsful of aromatic
spirits of ammonia with four ounces of peppermint water. Dose: one
tablespoonful; repeat if necessary." Ummm, yum!

Camphor is the main ingedient in Tiger Balm. Curiously, the brain
registers the scent of camphor pretty much the same as ammonia when
there is only a small amount of molecules present.

The stimulant properties of this type of molecule cause a physical
reaction that make you breathe faster and your heart beat faster.
That's what wakes you up. So, basically anything that has strong
stimulant properties when inhaled will cause you to wake up.
Personally, I'll stick with that pot of coffee sending out it's
molecules in the morning. It may not be as effective as smelling
salts, but it's much more pleasant!
