  • It has been reported that BEO has both antibacterial and antifungal activity against Campylobacter jejuni, Escherichia coli, Listeria monocytogenes, Bacillus cereus, and Staphylococcus aureus and dermatophytes, respectively (Karaca et al., 2007).

  • The in vitro activity of BEO against Candida species suggests BEO’s potential role in the topical treatment of Candida infections (Romano et al., 2005).

  • BEO is also active against dermatophytes in vitro (Sanguinetti et al., 2007).

  • Chitosan-based films containing BEO at 0.5, 1, 2, and 3% w/w showed a significant dose-dependent inhibitory effect on the growth of Penicillium italicum (Sánchez-González et al., 2010).

  • The in vitro effectiveness of the oil and vapors of bergamot and its components against common foodborne pathogens has been also investigated, and linalool was revealed to be the most effective anti-bacterial component (Fisher and Phillips, 2006).

  • Bergamot essential oil has also been found to inhibit the survival and proliferation of neuroblastoma cells, (Celia et al., 2013) through the activation of multiple pathways leading to both necrotic and apoptotic cell death (Ursino et al., 2010). Moreover, Russo et al. (2013) showed that association of limonene and linalyl acetate, but not the exposure to the single compounds, caused significant cytotoxicity, suggesting for a major role of the combined action of these monoterpenes in cancer cell death induced by BEO.

  • Bergamottine significantly decreased the electrocardiographic changes that are typical of coronary arterial spasms and the occurrence of experimental cardiac arrhythmias provoked by pitressin in guinea pigs. These results indicate that bergamottine possesses potential antianginal and antiarrhythmic properties (Occhiuto and Circosta, 1996)

  • Four studies evaluated the effects of different essential oil combinations, with BEO being a constituent of the mixture associated with lavender (Lavandula angustifolia), cedarwood (Cedrus atlantica), ylang ylang (Cananga odorata) or frankincense (Boswellia carteri)

  • Early research shows that taking a product containing bergamot extract and other ingredients for 6 months slightly reduces joint pain in people with joint pain caused by drugs called aromatase inhibitors.

  • Research shows that taking bergamot extract by mouth for 8 weeks may improve mental control and self-regulation in people with schizophrenia.

  • Bergamot’s ability to help us find balance comes in part from its ability to regulate the sympathetic and parasympathetic nervous systems. . When these systems are overburdened or overworked, they no longer work in harmonious partnership. Bergamot helps those systems to regain their balance.

Constituents

  • It is composed of both a volatile (93–96% of total)  mainly represented by monoterpene and sesquiterpene hydrocarbons, and their oxygenated derivatives, along with aliphatic aldehydes, alcohols, and esters. They include monoterpene limonene (25–53%) and high quantities of oxygenated compounds, such as linalool (2–20%), linalyl acetate (15–40%), γ-terpinene, and β-pinene 

  • The non-volatile fraction (4–7% of total) contains pigments, waxes, coumarins, and psoralens (such as 5-methoxypsoralen, also known as bergapten or 5-MOP, contained in about 0.2%), as well as bergamottine [5-geranyloxypsoralen]).

  • Due to the well-known 5-MOP-induced photo-toxicity, a furocoumarins-free essential oil has been prepared for perfumery and cosmetic uses. The vacuum distillation of bergamot peels provides a high-quality BEO totally devoid of 5-MOP that is chemically comparable to that of the cold-pressed oil.

  • Unlike sweet oranges, bergamot oranges are sour and not eaten fresh, despite the fact that the fruit is a good source of vitamin C, potassium, vitamins B1, B2, and A.

​

Energetics/ Organoleptics

  • SMELL: Sweet, light citrus scent with floral notes.  Delicately spicy/ zesty.

  • TASTE: Bitter and lemony (inedible)

  • COLOR: Greenish-yellow

  • FEEL: Thin

  • NOTE: Top note

  • ENERGETICS: Brightening, positive, lifting

  • ELEMENTS: wood and fire

  • CHAKRA:  Bergamot resonates with the fourth chakra, opening the heart and allowing love to radiate.

  • PLANETS / DIETIES: Mercury/ Persephone

  • MERIDIANS: According to TCM its energy is circulating and neutral to warming with and affinity for the liver, spleen, stomach, and heart meridians.

  • It works to reduce constraint in the liver, which is the organ and meridian that helps to maintain smooth and even flow of energy through the body and mind.

  • By helping to regulate the Qi and harmonize the Shen, Bergamot balances the body’s energies much like an adaptogenic herb.

  • Bergamot is cheering for us, helping to instill confidence in every ounce of our being. Bergamot helps to clear out from our cells the "old" energy, helps us transform ourselves, recreate ourselves and regenerate.

  • From an Ayurvedic perspective, Bergamot is balancing to Vata energy and can help reduce Pitta while increasing Kapha energies. Its affinity is for the Heart Chakra. Here, Bergamot helps to balance the fire, or driving force, of the body, which warms and dries the system with the solidity, or Kapha, of the body. In doing so, Vata energy, which is associated with the Air element, is given freedom to move once again. Bergamot’s action is through the heart or chest, where we manage our emotions. Bergamot helps the Heart center to balance and regulate the connection between thinking and feeling in a way that supports the whole system. By bringing Pitta into balance, Bergamot offers the heart the energy to heal past and current traumas, heal old wounds, and find compassion and nurturing for ourselves and those around us. Bergamot helps us to clear the heavy, clouded emotional energies of excess Kapha so our Vata or mind can see more clearly and create new patterns of thought based on that new insight.

  • Spiritual References: A naturally bright oil, Bergamot has long been associated with prosperity and material successes, and is thus a natural ingredient in money charms and spells. Bergamot is also sometimes used in love magic, as well as in rites for honoring spring.

 

Contradictions

  • Bergamot essential oil is a widely used aromatic ingredient in cosmetics that may be applied on sun-exposed skin areas, although components such as bergapten, citropten, bergamotene, and other furocoumarins may cause phototoxic effects.

  • Primarily due to the presence of psoralens, BEO preparations may pose phototoxic, genotoxic and carcinogenic risks. However, a layer of oil on the skin has no sensitizing effect, if not rubbed in, and it has been showed as BEO alone does not irritate the skin.

  • Bergamot essential oil rich in 5-MOP has been used as sun tanning products for many years. In 1995, this use was banned and limited to the treatment of certain skin disorders. Toxic reactions can occur due to psoralen or UVA overdosing or due to accidental exposure to additional UVA, including sunlight exposure. 

  • Earl Gray tea is composed of black tea and BEO. a 44-year-old man drank up to 4 L of black tea every day for 25 years. When he changed his brand because of occasional gastric pain, he began to drink the same daily quantity of Earl Gray tea. One week after the change, he noticed repeated muscle cramps. After 5 weeks of drinking the tea, the muscle cramps continued. Occasionally, he observed fasciculations, distal paraesthesia, and feelings of pressure in his eyes that were associated with blurred vision. Neurological examination confirmed reduced visual acuity and fasciculations. After 5 months, suspecting a relation between his symptoms and his tea intake, he stopped drinking Earl Gray, going back to black tea. Within 1 week, the symptoms completely disappeared.

  • Children: Bergamot oil is POSSIBLY UNSAFE in children when taken by mouth in large amounts. There have been serious side effects, including convulsion and death, in children who have taken large amounts of bergamot oil.

  • Surgery: Bergamot might lower blood sugar. There is some concern that it might interfere with blood sugar control during surgery. Stop using bergamot at least 2 weeks before a scheduled surgery.

  • Information regarding safety and efficacy in pregnancy and lactation is lacking.

  • Limited clinical studies in hyperlipidemia suggest bergamot juice is safe and well tolerated, although heartburn has been reported.

Proper Use

Bergamot oil is cold-pressed from the peel while the fruit is green in color and nearly ripe.

​

To get quality citrus oil without losing antioxidant and other beneficial properties, cold press extraction is required. Since the oil is taken from the peel, it is also vital that the source is organic and pure. Cold press extraction or scarification, is obtained by compressing the rinds of the citrus without the use of heat—thus the term “cold”.

​

Store your citrus oils in the refrigerator and use within 12-18 months after opening.

​

Cognitive Dysfunction 

An open-label pilot study demonstrated the effectiveness of bergamot-derived polyphenolic fraction (500 mg twice daily for 8 weeks as adjunctive therapy), on cognitive dysfunction in patients being treated for schizophrenia.

​

Dyslipidemia

Effects of bergamot-derived polyphenolic fraction on dyslipidemia has been studied at dosages of 500 mg/day and 1,000 mg/day for treatment durations of 1 month or 6 months. In a study of patients with moderate hypercholesterolemia, a standardized bergamot-derived extract (Bergavit) was given at a fixed daily dose (150 mg of flavonoids) for 6 months.

​

Formulary

LIP TREATMENT

Coconut oil with a few drops of bergamot essential oil makes a wonderful chapped lip and cold sore treatment in the winter. Keep a small jar handy and apply liberally.

​

MOOD ELEVATOR

Pair Bergamot with others that enhance relaxation and provide clarity of perspective, like lavender or atlas cedar wood. 

​

The aroma of Bergamot is lovely and complex and can easily stand on its own but it is also nice blended with other essential oils like clary sage, frankincense or ylang ylang, lavender, orange blossom, jasmine, cypress, geranium, lemon, chamomile, juniper, coriander, sandalwood, oak moss, patchouli, benzoin and violet leaf.

​

DIGESTIVE AID

Bergamot essential oil aids digestion and can relieve symptoms of colic and gas when massaged into the abdomen.

​

For Abdominal Cramps

  • 
9 drops Bergamot (Citrus bergamia)

  • 3 drops Lavender (Lavandula angustifolia

  • 4 drops Roman Chamomile (Chamaemelum nobile)

  • 2 drops Cypress  (Cupressus sempervirens)

​

Blend into 1 oz of unscented carrier oil and massage a tablespoon gently into the belly. Use clockwise circular motions.

​

MOUTHWASH

Bergamot essential oil can even be used as a mouthwash, thanks to its antimicrobial action and ability to fight bad breath.

​

NATURAL DEODORANT & AIR FRESHENER

Add a few drops of Bergamot oil to your air freshening spray, and to your deodorant, liquid soap, or laundry detergent. It smells great, removes bad odors, and stops the spread of germs and viruses.

​

Use the oil in massage blends, aroma diffusers, and baths. Along with neroli and lavender it is one of the principal ingredients in the classic Eau-de-Cologne.

​

in Europe it is used as a flavoring in cookies, custards, marmalades, syrups, and cocktails. It is also mixed with mayonnaise or pesto and served as a condiment with fish or meat entrees.

​

Cultivation

  • Bergamot is a small tree that grows up to 16 feet, with fruit that looks similar to small, pear shaped oranges.

  • The seed is best sown in containers as soon as it is ripe, after thoroughly rinsing it. Germination usually takes place within 2 - 3 weeks at 13°c. Seedlings are liable to damp off so they must be watered with care and kept well ventilated.

  • The seed is usually polyembryonic, two or more seedlings arise from each seed and they are genetically identical to the parent but they do not usually carry any virus that might be present in the parent plant.

  • When large enough to handle, prick the seedlings out into individual pots and grow them on until they are 10cm or more tall before planting out into their permanent positions.

  • Cuttings of half-ripe wood, July/August in a frame. This species grows easily from cuttings.

  • Layering in October.

History

  • Citrus bergamia is defined as a hybrid between a sour orange (C. aurantium L.) and lemon (C. limon L. Burm. f.) or a mutation of the latter. Others consider it a hybrid between a sour orange and lime (C. aurantifolia)

  • The word bergamot is etymologically derived from the Italian word "bergamotto",ultimately of Turkish origin: bey armudu or bey armut meaning "prince's pear" or "prince of pears")

  • It can be pronounced with a hard “t” or silent “t” (bear-guh-moh).

  • It is an endemic plant of the Calabria region (Italy)

  • Alternatively, it may originate from Antilles, Greece, and the Canary Islands, from where Christopher Columbus imported it. The name “bergamot” seems to be derived from Berga, the Spanish city from which the plant was transported in Calabria (south of Italy) later. C. bergamia trees are cultivated almost exclusively along the southern coast of the Calabria region (more than 90% of the world production of bergamot comes from this region)

  • Citrus bergamia is a small tree that blossoms during the winter. The juice tastes less sour than lemon, but more bitter than grapefruit.

  • The highly acid fruit juice is sometimes used as a vinegar or lime juice substitute.

  • Bergamot fruit is mainly used for its essential oils (bergamot essential oil: BEO) that are obtained by rasping and cold pressing the fruit peel.

  • BEO is widely used in perfume, cosmetics, food, and confectionery industries for its intense fragrance and freshness.

  • Bergamot juice, obtained from the endocarp after essential oils extraction, has long time been considered just a secondary and discarded product of the essential oil industry due to its bitter taste. Recently, it gained attention because of its hypolipemic and hypoglycaemic activity (Mollace et al., 2011), as well as its anti-inflammatory (Impellizzeri et al., 2014) and anti-cancer properties (Delle Monache et al., 2013; Navarra et al., 2014).

  • Bergamot essential oil is one of the main basic constituents for the manufacture of perfumes, due to its ability to fix the aromatic bouquet of aromas and harmonize all of the essences, enhancing the fragrance.

  • BEO is also used by the pharmaceutical industry, both to absorb the unpleasant smells of medicinal products and for its antiseptic and antibacterial properties.

  • BEO is also used in the food and confectionery industries as a flavoring.

  • In Italian folk medicine, it has been used primarily for fever and parasitic diseases, in addition to mouth, skin, respiratory and urinary tract infections, gonococcal infections, leucorrhoea, vaginal pruritus, tonsillitis, and sore throats (Pendino, 1998)
