Bergamot essential oil is derived from the bergamot orange, a fruit endemic to the Calabria region of Italy. You may already be familiar with its citrusy flavor--it is most notably used in Earl Grey tea! However, this isn't the only place that bergamot can be found. In fact, bergamot is probably already a part of your everyday life. It is a common ingredient in perfumes, food and drink, and even medicinal products.
