Brief introduction:
Bergamot is a small citrus tree cultivated primarily in southern Italy, particularly the Calabria region. The fruit resembles a small orange but is generally too sour and bitter to be eaten fresh. Its aromatic peel yields the highly prized bergamot essential oil, famous as the characteristic flavoring of Earl Grey tea and widely used in perfumery, aromatherapy, and herbal medicine.
Traditional uses:
-
Digestive support
-
Mood enhancement
-
Relief of nervous tension
-
Fragrant tonic
-
Aromatic baths
-
Appetite stimulation
-
Air purification
The oil has traditionally been valued more for its aroma than for internal medicinal use.
Historical use:
Bergamot cultivation became established in Italy during the seventeenth and eighteenth centuries. The essential oil rapidly gained popularity in European perfumery and later became famous through its use in Earl Grey tea. Traditional Italian folk medicine employed bergamot preparations for digestive complaints, fevers, and emotional distress.

Clinical studies suggest bergamot aromatherapy may help reduce anxiety and stress in some individuals.
-
Laboratory research demonstrates antimicrobial activity against various bacteria and fungi.
-
Studies indicate potential effects on mood, relaxation, and emotional well-being.

Apothecary Records Note:
Bergamot is best known as the signature flavor of Earl Grey tea, but its greatest medicinal importance lies in its essential oil. Care should be taken not to confuse Bergamot (Citrus × bergamia) with Monarda didyma or related Monarda species, which are sometimes called "bergamot" in North American herbalism. Although they share a similar fragrance, they are entirely different plants with distinct medicinal properties.
