Essential Oil of Bergamot

Latin Name Citrus aurantium (L.) var. bergamia or Citrus bergamia (Risso)

Family Rutaceae

Pronunciation bûr´gumot

Essential Oil Monographs

Common Names Bergamot, bergamot orange, bergamota, bergamotier, bergamoto, bergamotte, bergamotto bigarade orange, and oleum bergamotte Do not confuse bergamot C. aurantium var. bergamia essential oil with the essential oils derived from bitter orange Citrus aurantium (L.) (also called petitgrain) or sweet orange C. sinensis. Also, do not confuse it with the herb called wild bergamot Monarda spp., a tall perennial with a spiked floret of red or purple flowers. This herb is also known by the name bergamot, but it does not yield an essential oil.

Sources Bergamot C. aurantium var. bergamia oil is obtained from the peel of the fruit, or from the whole fruit. It is grown near the Mediterranean, including Southern Italy, Sicily, and Spain. It is also grown and produced in Brazil.

History The oil of the bergamot C. aurantium var. bergamia has a long history of use as an essential ingredient in potpourri, body powders, and perfumes. Christopher Columbus originally discovered it in the Canary Islands. By the 16th century, it was popular throughout Europe and has been mentioned in a number of old herbal texts. In Italian folk tradition, it is a remedy for fever and infection.

Parts Used Bergamot C. aurantium var. bergamia oil is obtained from the peel of the inedible fruit by a method known as expression. Bitter orange oil C. aurantium (or petitgrain) is obtained from the leaf and twigs. Though it is not very common, it is sometimes used to adulterate neroli essential oil distilled from the flowers of C. aurantium var. amara.

Cultivation Citrus trees thrive in a warm climate and require well-drained, well-aerated, and moderately fertile soil. Bergamot trees are grafted on stubs of bitter orange. The fruit of this variety is inedible and is about the size of a big orange, but it is lemon shaped. The tree 8 Master the Basics of Aromatherapy and the Poewr of Smell ÂŠ 2020 American College of Healthcare Sciences. All duplication prohibited.

is easily damaged by frost. It bears fruit when it is approximately six to seven years old. If it is grown in hot, dry summers, the ester content is increased and higher quality oil is produced. (An ester is a chemical constituent of essential oils that helps to produce a potent aroma.)

Harvesting & Production The fruit is allowed to dry and harden before processing. It is then placed in a trough, which is lined with sharp projections long enough to pierce the oil glands in the outer portion of the peel. A fine spray of water washes the oil from the mashed peel while the juice is removed by rotating it at a very high speed. This same process is repeated with the peel only. The oil is separated using a separatory funnel or an industrial application using a similar technology.

Characteristics Open your sample of bergamot C. aurantium var. bergamia. See if you can identify the following. Note your own experience of the aroma, color, and feel in your notebook. Aroma •Spicy citrus aroma Color •Greenish-yellow Feel •Thin and with a slight oily sensation when you rub it between your fingers. Perfume blotter test •It leaves a slight yellowish stain on the perfume blotter.

Essential Oil Monographs

Active Constituents Bergamot C. aurantium var. bergamia oil contains: •

•

• •

•

Up to 50% limonene (approximately): A common terpene found in many oils, including: Citrus, peppermint M. ×piperita, caraway Carum carvi (L.), pine P. sylvestris, cardamom Eletteria cardamomum (L.), coriander C. sativum, and juniper J. communis. Terpenes are anti-inflammatory, antiseptic, antiviral, and bactericidal. Up to 40% linalyl acetate (approximately): An ester and anti-inflammatory, and a main constituent of lavender oil. The percentage of the ester linalyl acetate determines the quality of the oil. Esters are antifungal, antimicrobial, and sedative. Up to 20% linalool (approximately): A monoterpenol with antibacterial, antifungal, vasoconstrictive, and toning properties. Bergaptene (you may also see it spelled as bergapten): A terpene that is a skin irritant. Terpenes are anti-inflammatory, antiseptic, antiviral, and bactericidal. Bergamot is also available with the color and bergaptene removed. (Bergaptene is the constituent that causes skin photosensitivity.) Though it is not necessary to remove the color to remove the bergaptene, many cosmetic manufacturers do not like the green tinge the oil imparts to preparations. Much of bergamot oil available is bergaptene-free because of this potential irritation. If you see it listed as Bergamot BF or Bergamot FCC, it is bergaptene-free. For holistic aromatherapy purposes, it is preferable to have the bergaptene and color present, but use caution with topical application. A range of constituents in smaller quantities.

Storage As we have learned limonene, linalool, and linalyl acetate are prehaptens. Once they are exposed to air/oxygen the prehapten is activated and forms sensitizing compounds in the essential oils. This is why it is so important to store all essential oils containing these constituents in a cool and oxygen free environment. Storage is very important for bergamot as citrus oils can oxidize quickly and spoil. Store in the refrigerator in a dark, airtight glass bottle.

Therapeutic Uses Bergamot C. aurantium var. bergamia essential oil may provide support for: Abdominal cramping, abscesses, acne, anger, anxiety, bad breath, boils, sinus and head congestion, cramps, cystitis, depression, emotional imbalances, fear, frustration, halitosis, herpes 10 Master the Basics of Aromatherapy and the Poewr of Smell © 2020 American College of Healthcare Sciences.

(mouth), indigestion, infection, inflammation, insect bites, insect repellent, loss of appetite, mouth infections, oily skin, scabies, shingles, skin infections, slow circulation, sore throat, stings, ulcers (skin), varicose veins, and wounds. Bergamot C. aurantium var. bergamia is useful for several skin issues (such as abscesses, acne, and shingles) because of its analgesic1 and vulnerary actions. Bergamot C. aurantium var. bergamia is also an insecticide (it can be used to destroy insects) and an insect repellent (which can help to prevent future insect bites). Mix five drops of essential oil with one ounce of base oil and apply. For herpes, blend bergamot C. aurantium var. bergamia with eucalyptus E. globulus and geranium P. graveolens for optimal effect. For herpes of the mouth, apply with a cotton ball directly. Gargle with two drops in one-half cup of warm water for a sore throat. Bergamot C. aurantium var. bergamia essential oilâ&#x20AC;&#x2122;s astringent action makes it useful for oily skin and varicose veins. Use a cold compress (see the Formulas section) or add two drops to a warm bath. It is also stimulating and rubefacient, increasing circulation and bringing increased blood flow to the skin. These therapeutic actions make it helpful for slow circulation. Add five drops to one ounce of base oil and apply. Further, bergamot C. aurantium var. bergamia has an antidepressant action. Note that this action is historical and anecdotal, and has not been proven in large studies. However, a recent study with 58 hospice patients was able to demonstrate bergamot C. aurantium var. bergamia essential oilâ&#x20AC;&#x2122;s antidepressant and analgesic actions. The hospice patients were given hand massages once a day for one week with an essential oil blend in 1.5% dilution with sweet almond oil. The essential oil blend consisted of bergamot C. aurantium var. bergamia, frankincense Boswellia carterii (Birdw.), and lavender L. angustifolia essential oils in equal ratios. All patients receiving the aromatherapy hand massage reported less pain and depression.2 For depression, bergamot C. aurantium var. bergamia can also be blended with rose attar R. damascena and sandalwood S. album. Add three drops to a full bath.

Bergamot C. aurantium var. bergamia is considered one of the most effective oils for mental, emotional, and psychological problems. A study with 36 female high school students showed inhaling bergamot C. aurantium var. bergamia essential oil daily helped with stress management when compared to inhaling a non-scented vegetable oil.3 Another study with schoolteachers also showed daily inhalation of bergamot C. aurantium var. bergamia essential oil helped with lowering anxiety.4 Researchers even demonstrated in an animal study with mice that bergamot C. aurantium var. bergamia essential oilâ&#x20AC;&#x2122;s anxiety relieving properties can be as strong as diazepam (valium).5 However, in this animal study, mice received injections of bergamot C. aurantium var. bergamia essential oil and this does not mimic standard aromatherapy protocols of inhalation or topical application. Add two drops bergamot C. aurantium var. bergamia essential oil to a safe diluent and mix into a warm bath or mix five drops with one ounce of base oil and apply. Bergamot C. aurantium var. bergamia is antibacterial (destroys or suppresses the growth or reproduction of bacteria) and antiseptic (prevents, resists, and counteracts decay).6 It can be dispersed in air, greatly reducing the presence of micro-organisms and is antiinflammatory (capable of counteracting or suppressing inflammation). All of these actions make it very helpful for use with infections. It is also useful for colds, flu, and coughs because of its expectorant action (encourages the discharge of mucus from bronchiopulmonary passages). For sinus and head congestion, use one to two drops on a tissue and inhale. Bergamot C. aurantium var. bergamia is useful for indigestion due to its digestive (aids in the digestion of food), carminative (stimulates intestinal peristalsis, relieves and promotes the expulsion of gas from the gastrointestinal tract), and antispasmodic (relieves nervous irritability and reduces or prevents excessive involuntary muscular contractions and spasms) actions. For indigestion, gas, or abdominal cramping, add one drop to one teaspoon of base oil and massage the stomach area clockwise. Bergamot C. aurantium var. bergamia essential oilâ&#x20AC;&#x2122;s aperitive (stimulates the appetite) action makes it helpful for loss of appetite. Try adding two drops to a warm bath.

In addition, bergamot C. aurantium var. bergamia essential oil’s deodorant action, along with its antibacterial action, make it helpful for halitosis, or bad breath. Put one drop in one-half glass of warm water. Stir rapidly, and then use to rinse the mouth.

Household Uses Bergamot C. aurantium var. bergamia oil is added to Earl Grey tea, giving it its characteristic flavor. Hard candy is flavored with bergamot C. aurantium var. bergamia for its sweet and fruity, yet refreshing flavor. It is also used to fragrance tobaccos, especially pipe tobaccos and potpourri. In commercial foods, bergamot C. aurantium var. bergamia oil is widely used as a citrus flavoring agent, including up to 0.02% in gelatins and puddings. Bergamot C. aurantium var. bergamia oil that is bergaptene-free is used in cosmetics manufacturing (up to 3% in perfumes and 0.25% in creams and lotions), in soaps, and suntan oils. Other household and culinary uses include: •

• • • • •

Bathroom cleaner, room spray, or surface cleaner: Use two to three drops undiluted on a damp cleaning cloth to wipe surfaces; add five drops to two cups of white vinegar to make a surface cleaner; or make a paste with onehalf cup of baking soda (add enough water to form a paste, and then add eight drops of bergamot) and use to clean bathroom surfaces. Carpet cleaner: Add eight drops of oil to one-half cup baking soda. Sprinkle on carpet: Wait 10 minutes, then vacuum thoroughly. Clothes dryer: Add two drops to a small cloth and add to dryer. Washing machine: Add two to five drops with softener or in the final rinse. Refrigerator: Put one drop on a wet cloth, and then wipe down surfaces to deodorize your refrigerator. Dishwashing liquid: Because it is an antibacterial (also called a bactericide), bergamot is useful added to dishwashing liquid: Add eight drops to a bottle of dishwashing liquid and shake before use.

Essential Oil Monographs

Perfumery Bergamot C. aurantium var. bergamia is an important and classic perfume material. It gives a delicate top note, along with strength and body, to a fragrance blend. Unlike most citrus oils, it does have a certain fixative effect when used in high concentrations. It imparts a refreshing characteristic eau de cologne fragrance. The fresh citrus fragrance has an uplifting effect on the mind. Oils that blend well with bergamot include: Bergamot C. aurantium var. bergamia blends well with chamomile Roman C. nobile, coriander C. sativum, cypress C. sempervirens, geranium P. graveolens, jasmine J. grandiflorum, juniper J. communis, lavender L. angustifolia, lemon C. limonum, neroli C. aurantium var. amara, rose attar R. damascena, sandalwood S. album, and violet Viola odorata (L.).

Recommended Daily Use Topical application: Adults: Dilute 1 drop in 2 teaspoons (10ml) of carrier oil or another safe diluent. Use this diluted preparation over a 24-hour period in 3 to 4 topical applications, or use the complete amount for one full bath. The dilution ratio is 0.4% to avoid photosensitivity. Rectified, furanocoumarin free bergamot essential oil can be used at higher dilution rates without risk of photosensitivity. Note: These dilution ratios are based on the conversion of 30 drops of essential oil = 1ml. Inhalation: Adults: Inhaled via a diffuser. Note: When diffusing, don't exceed 30-minute intervals and diffuse in well-ventilated areas. If any adverse reactions occur, discontinue use and consult with a physician.

Cautions and Contraindications Bergamot C. aurantium var. bergamia oil has Generally Recognized as Safe status (GRAS) for use in foods in the U.S., and is on the Substances Added to Food List, which means it is likely safe when consumed orally in amounts commonly found in foods. 7 8 Care should be taken with topical application as it is photosensitizing; because of the bergaptene content it can cause abnormal skin pigmentation when skin is exposed to sunlight or sunbed, and it may even lead to malignant changes in the skin.9 10 This action is intensified if the bergamot C. aurantium var. bergamia is blended with alcohol. The quantity of bergamot essential oil in a finished product intended for topical use should be 0.4%. If you do use a product that contains bergamot essential oil and it is not bergaptene-free, wait for at least 12 hours before exposing skin to the sun or using a tanning bed.11 Note, the bergamot in your Essential Oil Kit includes bergaptene, so use care when applying externally. As a general rule the color of bergamot reveals if it is bergaptene free or not. Regular bergamot is yellow-green (olive), bergaptene-free is pale yellow, almost clear. Some authors recommend avoiding bergamot during pregnancy and nursing. However, Tisserand concludes that it can be used during pregnancy due to the low toxicity of limonene and linalool.12 He also states there is a suggestion that (+)- limonene crosses the placenta, and that it may have beneficial effects on fetal health, for example in smokers.13 ACHS recommends caution. While many things cross the placental barrier, if it is not essential to use bergamot essential oil during pregnancy why risk fetal health with a substance the effects of which are not truly known.

As with all essential oils, bergamot C. aurantium var. bergamia oil is likely unsafe when ingested by children in large amounts.14 Do not use at the same time as photosensitizing drugs, because the bergaptene content can compound photosensitizing effects and increase the risk of side effects.15 SAFETY TIP BERGAPTENE AND ANTIPLATELET ACTION Bergaptene also spelled as bergapten is a furocoumarin found in bergamot essential oil amongst others, that has demonstrated antiplatelet activity in research. 16 Any essential oil with more than 5% bergaptene should be used with extreme care and never orally where these conditions exist: anticoagulant drugs, surgery, childbirth, peptic ulcer, hemophilia or other bleeding disorders. Always check the safety precautions for each oil and follow the administration guidelines and dose and duration. Duration of exposure is as important as concentration. This is an important safety consideration throughout your studies. Always consider dose and duration whenever you use essential oils.

Essential Oil of Chamomile Roman

Figure 3: Chamomile Roman Chamaemelum nobile. Image by Dorene Petersen. ÂŠ 2005

Latin Name Chamaemelum nobile (L.) All. (formerly Anthemis nobilis (L.))

Family Asteraceae According to the British Pharmacopoeia, the cultivated double variety of C. nobile is the variety used for oil extraction. Do not confuse it with Blue or German chamomile Matricaria recutita (L.) or chamomile maroc Ormenis multicaulis Chamomile Roman and Blue chamomile can be easily distinguished in nature. Chamomile Roman is a perennial with scented foliage that smells extremely strong, somewhat like green Granny Smith apples. Blue chamomile is an annual and the foliage has no scent. Chamomile Roman has slightly hairy stems, while those of Blue chamomile are smooth. The flowers of Roman chamomile sit singly atop the stem, while those of Blue chamomile are on divided stems in a comb-like arrangement. Another distinct characteristic is the cone in the center of Blue chamomile which distinctly domes out, whereas chamomile Roman is flat. (Braun-Blanq. & Maire). Chamomile maroc should not technically be called chamomile. Botanically and chemically it is not related. It should not be considered a replacement for either C. nobile or M. recutita.

Essential Oil of Eucalyptus

Latin Name Eucalyptus globulus (Labill.) There are several species of eucalyptus used to produce essential oil. Some of the more common include: Eucalyptus australiana (R.T.Baker & H.G.Sm.), Eucalyptus leucoxylon (F. Muell.), Eucalyptus polybractea (R. T. Baker), and Eucalyptus sideroxylon (A. Cunn. ex Woolls). Eucalyptus citriodora (Hook.) and Eucalyptus smithii (R.T. Baker) are two additional species, which we will study in separate monographs. In this monograph, we focus on E. globulus.

Essential Oil Monographs

Pronunciation ˌyü-kə-ˈlip-təs24

Common Names Gum tree, blue gum, stringy bark, and fever tree

Sources Eucalyptus is a tree native to Australia and Tasmania, although it is now found on many continents. At present, about 25 eucalyptus species are used to produce oil. Eucalyptus globulus is produced in China, Brazil, Paraguay, Australia, South Africa, and Spain.

History Eucalyptus is a Greek word meaning “well covered,” which refers to the lid-like cover of the bud. In the late 19th century, eucalyptus was frequently planted in marshy areas. Its heavy water requirements made it extremely useful in preventing the malarial fever epidemics in swampy areas. The eucalyptus tree is one of the earliest used native medicines in Australia. Parts Used Eucalyptus E. globulus essential oil is extracted by steam distillation from the fresh or partly dried leaves and twigs.

Cultivation Eucalyptus is a large tree, with varied foliage and flowers. Some species have interesting ornamental bark. It is now planted worldwide in regions with a subtropical or Mediterranean climate. Eucalyptus is a rapid grower, often reaching heights of 300 feet. Eucalyptus globulus, the blue gum, is very sensitive to abrupt weather

changes and frost, but it adapts very well to dry soils. The red gum Eucalyptus rostrata (Schltdl.) resists both drought and flooding and withstands extreme heat, thriving in alkaline soil. Generally, eucalyptus grows well in a variety of soil types, but it does best in a rich loam.

Harvesting & Production Eucalyptus E. globulus oil is usually harvested by hand and the trees are kept shorter and coppiced. It is steam distilled from the fresh or partly dried leaves and young twigs. The age of the leaves does not affect the composition of the oil.

Characteristics Open your sample of eucalyptus. See if you can identify the following. Note your own experience of the aroma, color, and feel in your notebook. Aroma •Characteristic, aromatic, somewhat camphoraceous aroma, and somewhat bitter, astringent taste

Color •A colorless or pale-yellow liquid

Feel •Eucalyptus oil feels thin but slightly oily when rubbed between the fingers.

Perfume blotter test •It should evaporate quickly and leave no stain on the perfume blotter.

Essential Oil Monographs

Active Constituents Eucalyptus E. globulus oil contains approximately: •

• •

66-84% 1,8 cineole, also known as eucalyptol. Eucalyptol is called cajuputol when it is found in cajuput, but essentially, eucalyptol, 1,8 cineole, and cajuputol are the same constituents. 1,8 cineole is an oxide and has anti-inflammatory, mucolytic, antispasmodic, and expectorant properties including 4-15% alphapinene, 1-3% limonene, 1-3% cymene, phellandrene, and terpinene. Common monoterpene characteristics are analgesic, bactericidal, expectorant, and stimulant. The sesquiterpene caryophyllene also has been found in eucalyptus. Sesquiterpenes are analgesic, anti-allergic, anti-inflammatory, antiseptic, hypotensive, and spasmolytic. A range of constituents in smaller quantities.

Eucalyptus E. globulus oil is frequently rectified, which means that the minor active constituents (such as the sesquiterpenes, alcohols, and phenols) are removed by redistillation since they may have irritant properties. If you see eucalyptus E. globulus oil described as 80/85 NF, it means the eucalyptol content is between 80-85%, the standard set by the U.S. National Formulary. It is usually standardized with either synthetic or naturally derived eucalyptol. Eucalyptus E. globulus oil is difficult to reproduce synthetically, as it contains more than 250 chemical constituents.

Storage As with all essential oils, it should be stored at cool temperatures and in well-filled containers protected from light.

Therapeutic Uses Eucalyptus E. globulus essential oil may provide support for: Abscesses, blisters, boils, bronchitis, bruises, burns, Candida, catarrh, chicken pox, chills, colds, cough, cuts, cystitis, fever, flu, headache, infection, influenza, insect bites, laryngitis, measles migraine, mucus, muscle stiffness, rheumatism, sinus congestion, sinus infection, sinusitis, skin infection, skin ulcers, sore throat, sprain, viral infection, and wounds. Eucalyptus E. globulus is a very effective analgesic with an immediate pain relief and soothing action.

For influenza, coughs and colds in adults and children over ten years of age, put one teaspoon of eucalyptus oil in a pan full of water; leave on a very low heat on a stove top in an adjacent room so the vapors waft into the bedroom. For adults vaporize for one to two hours and for children over ten reduce the time to 30 minutes. A vaporizer or diffuser that cycles on and off will work in the same fashion. This creates vapors that are high in the antiseptic essential oil. The volatile molecules disperse throughout the room and help break up the mucus, as well as reduce the coughing. Note: prolonged inhalation is not advisable for children under ten years of age.32 Duration of exposure is as important as concentration. This is an important safety consideration throughout your studies always consider dose and duration whenever you use essential oils. Eucalyptus E. globulus is a febrifuge, which reduces fever. This action is important for use with chills, fever, influenza, and pneumonia. Use a vaporizer, diffuser, or hot water diffusing method as outlined above.

Household Uses Eucalyptus E. globulus oil is an effective antiseptic to use around the home. Its many uses include: • • • • • • • •

Dishcloth disinfectant: Soak cloths in a bowl with one drop of eucalyptus. Cleaner: Dissolve the sticky remnants of tape on furniture, floors, and appliances. It can, however, lift the varnish and finish from wooden furniture, so use with care. Sanitizer: Fumigate rooms or use to sterilize toilet and bathing areas. Floor cleaner: Add three teaspoons to a bucket of boiling water when scrubbing floors. Spot and stain remover. Toilet deodorizer: Place two drops in inner cardboard roll of toilet roll. Light a bulb ring in the bathroom with two drops of eucalyptus. Shoe deodorizer: Impregnate blotting paper and leave in sports shoes overnight.

Because of the high eucalyptol (1,8 cineole) content eucalyptus E. globulus essential oil should not be applied full strength to the face, eyes, or nose. It should not be applied to the face or nose of infants or children under 10 years of age.40 Dose and duration of use are vital issues to consider when an oil has a high eucalyptol (1,8-cineole) content. While there is no scientific evidence it is a generally accepted practice not use at the same time as homeopathic remedies, as it may limit their effectiveness. It is also contraindicated if there is a history or diagnosis of asthma, chronic obstructive pulmonary disease, hypersensitive clients41, or gastrointestinal inflammation, and liver and bile duct complaints.42 Note according to Tisserand this is not necessary but he goes on to say “that some essential oils may present a risk to some classes of hypertensive patient, in certain dose/route combinations, and there may be a theoretical argument for exercising caution in certain cases of hypertension and hypotension. However, until we know more about where the risks lie, there is no case for contraindication of any essential oils.” 43 ACHS recommends to always err on the side caution and avoid in cases of chronic hypertension particularly when someone is on antihypertensive medication. It can cause stinging on the skin if applied undiluted. Eucalyptol can irritate both the skin and mucous membranes. The maximum dilution in a finished product should be 20% and the German Commission E Monograph for eucalyptus oil recommends 5–20% for dermal applications.44 However more recently the International Fragrance Association (IFRA) and Scientific Committee on Consumer Safety classify eucalyptus as a skin sensitizer with a code R43.

Do not use eucalyptus E. globulus oil undiluted on wounds or skin inflammation. Do not apply full strength to the face, eyes, or nose. Even diluted it should never be applied to the face or nose of infants or children under 10 years of age. For children over the age of ten it can be applied diluted topically (not hear the face or nose) for a limit of two to three days. It must be kept out of reach of children, as should all essential oils, and never given orally to children and with extreme care in adults.

Sources Lavandula officinalis is grown commercially for essential oil production in France, Bulgaria, Moldova, and Ukraine. The small bottles of lavender found in most aromatherapy stores may be steam distilled from either lavender L. officinalis, spike lavender L. latifolia, or lavandin L. ×intermedia. It is important to understand and recognize the differences between them as they all may be named just by the common name. True Lavender Lavandula angustifolia (Mill.)

This is a dwarf shrub yielding a relatively small yield of oil distinguished from other lavender oils by being entirely free of camphor. Its natural habitat is restricted to a small area above a 3,281-foot (1,000 meters) altitude in the southern French Alps. Lavender L. angustifolia is the true lavender that grows wild at altitudes of 2,296 to 3,609 feet (700 to 1,100 meters) in southern France. It produces the finest essential oil, with high ester content and a sweeter aroma. The wild lavender L. angustifolia has a smaller blossom cluster than commercially grown lavender L. angustifolia. Lavandula angustifolia is often referred to in France as female lavender. It is also grown commercially and is the more usual source of the L. angustifolia you can purchase. The wild harvested L. angustifolia is very rare and only a few distillers are producing it. You will recognize L. angustifolia by its Figure 8: High altitude wild lavender Lavandula sweeter aroma. angustifolia in Provence, France. ACHS Summer Study Abroad. Image by Dorene Petersen. © 2001

Spike Lavender Lavandula latifolia (Medik.)

This is a strong-growing shrub giving a fairly large yield of oil. You will recognize L. latifolia by the strong aroma of camphor. It occurs naturally at lower altitudes around the northern Mediterranean shore, particularly Spain and Italy. It is also grown in England, the United States, Japan, and Tasmania. Spike lavender L. latifolia oil is quite harsh and is used mainly for scenting soaps and laundry detergents. It is often referred to in France as male lavender. Lavandin Hybrid Lavandula ×intermedia (Emeric ex Loisel.) At medium altitudes in the south of France, the “male” spike lavender and the “female” true lavender intermingle and give rise to a very wide range of hybrids. As commonly occurs with this type of crop, the hybrid is sterile but stronger growing than either parent. It provides very large yields of oil that is high in camphor. France produces more than 1,000 tons of this plant a year. There are several clones of the lavandin L. intermedia that are popular, including grosso, super, and abrialis. All of these produce oils with varying components, some closer to “true” lavender L. angustifolia than others. You study lavandin in a separate monograph. 40 Master the Basics of Aromatherapy and the Poewr of Smell © 2020 American College of Healthcare Sciences. All duplication prohibited.

History The botanical name Lavandula comes from the Latin lavare meaning “to wash.” The use of lavender L. angustifolia as a strewing and bathing herb by the Romans is well documented. It was one of the ingredients of the Four Thieves vinegar famous in the Middle Ages. During this time, Europeans used dried lavender L. angustifolia flowers under their pillows to ward off evil spirits. It was used extensively for medicinal purposes up until the 18th century in Britain.

Parts Used The oil is distilled from the flower stalks and flowers. Higher-quality oil is distilled from just the flowers, which are stripped from the stalks before distillation.

Cultivation The plant can be grown from seed, which is referred to as population lavender L. angustifolia, and is said to give the highest-quality essential oil. It is usually propagated by cuttings or divisions. Growth can be slow and the plants do not produce any considerable quantity of flowers for about three years. It grows best in a light soil (sand or gravel) in a dry, open, sunny position. It needs good drainage, particularly in winter. It grows in soils where few plants can survive and is said to produce the best-quality oil when the soil is very poor.

Harvesting & Production The flowering crops are harvested when in full bloom and during the hottest time of the day. For best results, the flowers are steam distilled with no previous drying or fermentation. Fresh lavender L. angustifolia gives a greater yield of oil with a higher ester content. Some distillers prefer to let the cut and bundled flowers and stalks dry for up to three to four days in the field before distillation to reduce the water content (hence lowering the cost of production.) Note there is also an absolute available from L. angustifolia. However, it apparently causes more skin reactions than steam distilled lavender. (See Cautions and Contraindications below.) 41 Master the Basics of Aromatherapy and the Poewr of Smell © 2020 American College of Healthcare Sciences. All duplication prohibited.

Characteristics Open your sample of lavender L. angustifolia. See if you can identify the following. Note your own experience of the aroma, color, and feel in your notebook.

Aroma •Fresh. High altitude lavender has a sweeter note.

Color •The color can range from colorless to pale-yellow or yellowish-green.

Feel •It has a slick sensation when you rub it between your fingers. It absorbs quickly.

Perfume blotter test •It does not leave a stain on the perfume blotter.

Active Constituents Lavender L. angustifolia essential oil contains: •

• •

Up to approximately 40% linalyl acetate and 4.2% lavandulyl acetate esters. The constituents of different species differ in their content of the ester, linalyl acetate, due to altitude. If lavender is grown above 2,000 feet, the ester content is increased, producing oil that is more valuable. The esters impart important therapeutic qualities to the oil, making it an effective soothing, balancing oil with an antimicrobial action. Up to approximately 31.5% linalool, a monoterpenol with antibacterial, antifungal, vasoconstrictive, and toning properties Up to approximately 6.7% z-beta-ocimene 42 Master the Basics of Aromatherapy and the Poewr of Smell © 2020 American College of Healthcare Sciences. All duplication prohibited.

Essential Oil Monographs

â&#x20AC;˘ â&#x20AC;˘

Up to approximately 5.16% beta-caryophyllene, a sesquiterpene with antiinflammatory properties A range of constituents in smaller quantities (There will be some variation depending on the country of origin, which is of course true for all essential oils.)

As you can see in the chart below, lavender L. angustifolia and lavandin L. intermedia have quite different chemical constituent profiles. As we have learned previously, the constituent profile affects the therapeutic outcome of the oil. Lavandin L. intermedia contains both camphor and 1,8 cineole (lavender L. angustifolia usually contains none). The camphor and 1,8 cineole can be stimulating (not sedating), which is the expected outcome when using lavender L. angustifolia. This can lead to a disappointing essential oil therapy experience.

Storage As with all essential oils, it should be stored at cool temperatures and in well-filled containers protected from light.

Therapeutic Uses Lavender L. angustifolia essential oil may provide support for: Acne, anxiety, bruises, burns, cough, depression, headaches, herpes ulcers, infections, insomnia, insect bites and stings, menstrual pain, migraine, muscle spasms, nervous irritability, nervous indigestion, scalds, sores, sore throat, sprains, teething pain, and wounds. 43 Master the Basics of Aromatherapy and the Poewr of Smell ÂŠ 2020 American College of Healthcare Sciences.

Further, lavender L. angustifolia is an excellent nervine, helping to tone and heal the nerves. Lavender L. angustifolia essential oil’s nervine action can ease nervous indigestion, insomnia, and stress.52 Lavender L. angustifolia is also antidepressant, helping to ease feelings of depression.53 Use in a diffuser or add four drops mixed with a safe diluent in a full bath. Lavender L. angustifolia is also an excellent sedative, helping to calm and tranquilize the nerves, which helps to relieve anxiety.54 This action of relieving anxiety is also known as anxiolytic. Be sure to use true lavender L. angustifolia, and not lavandin L. intermedia, which contains a high proportion of camphor and is a stimulant! Use in a diffuser or use four drops mixed with a safe diluent in a full bath.

Household Uses Lavender L. angustifolia oil is used extensively to fragrance soaps and air fresheners, and it can be used around the home as a very effective deodorizer and air freshener: • • • • •

Lavender L. angustifolia pillows and sachets are wonderful in linen cupboards and chests of drawers and will keep away moths and other insects while imparting a fresh scent. For your closet, soak blotting strips in lavender and place on the shelves. To clean carpets, add one drop of lavender L. angustifolia oil to one tablespoon of borax. Sprinkle over the carpet, wait a few minutes, then vacuum. For a fresh scent for ironing, put four drops directly into the steamer of your iron with the water. Lavender L. angustifolia oil can be sprayed from an atomizer or left in a saucer to help keep away ants and insects, and to disinfect the air.

Perfumery Lavender L. angustifolia has a sweet, floral-herbaceous, refreshing aroma with a pleasant, balsamic-woody undertone. The fruity-sweet top note is short lived and the base note is not long lasting.

Essential Oil of Peppermint

Latin Name Mentha ×piperita (L.)

Family Lamiaceae

Pronunciation ˈpepə(r)ˌmɪnt59

Common Names Balm mint or brandy mint 59 Peppermint - pronunciation of peppermint by Macmillan Dictionary. Macmillandictionary.com. (2020). Retrieved 9 July 2020, from https://www.macmillandictionary.com/us/pronunciation/british/peppermint.

Essential Oil Monographs

Sources Peppermint M. ×piperita is cultivated in the United States, which is the largest producer. But Eastern Europe, Bulgaria, Italy, and Morocco also produce large enough quantities to report significant exports of peppermint oil.

History The name comes from the Greek myth of the nymph Minthe. Discovered by Persephone in the arms of her husband Pluto, Minthe metamorphosed into a “sweet smelling herb to be trampled underfoot.” Other writers connect mentha with the Latin word mente, meaning “thought.” Records of the uses and preparation of mint are found in the Ebers papyrus, the oldest surviving medical text. An ingredient in the sacred incense kyphi, it was used in ancient Egypt as a ritual perfume and was cultivated by the Egyptians. The hieroglyphics found in the temple of Edfu refer to this. The Greeks and Romans crowned themselves with peppermint at their feasts and it was used to flavor both sauces and wine. Its use was mentioned in the Icelandic Pharmacopoeias of the 13th century. However, it did not come into use in Western European Pharmacopoeias until about the middle of the 18th century. It was added to the London Pharmacopoeia in 1721.

Parts Used The oil is distilled from the leaves, flowers, and stems.

Peppermint M. ×piperita is a perennial that can be propagated by seed, cuttings, or rooted runners. Peppermint requires a rich, moist soil with good drainage. The soil pH should be neutral to slightly alkaline. It prefers full sun. Liberal use of compost is recommended and the quantity and nature of the fertilizer has a great effect on the characteristics of the oil.

Essential Oil Monographs

Harvesting & Production Moderate climatic stress increases the yield of the oil while reducing the amount of the herb. Environmental stress increases the sesquiterpene levels in the oil. The leaves and flowers are harvested just before maturity, when the essential oil content is greatest. In large commercial fields in the United States the plant is harvested directly into the retort, which is a large metal box on wheels. Steam is injected directly into this vessel once it is wheeled back into the distillery.

Characteristics Open your sample of peppermint M. ×piperita var. Black Mitcham. (This variety is grown in Washington State, USA). See if you can identify the following. Note your own experience of the aroma, color, and feel in your notebook.

Aroma •Fresh, strong, somewhat grassy, mint-like, reminiscent of candy canes Color •Clear to pale-yellow or pale-olive color Feel •It feels thin, but dry when rubbed between the fingers. Perfume blotter test •It does not leave a stain on the perfume blotter.

Peppermint M. ×piperita is a powerful essential oil for the gastrointestinal system. It can neutralize acid in the stomach and intestinal tract, and is an antispasmodic61 62, carminative63, and stomachic.64 In a randomized, double-blind clinical trial, the anti-emetic65 action of peppermint M. ×piperita essential oil was shown to help relieve the nausea and vomiting of chemotherapy patients in the first two hours following their treatments.66 The antibiotic action of peppermint M. ×piperita has also been shown to play a role in relieving irritable bowel syndrome and intestinal dysbiosis.67 Peppermint is also proving effective against multidrug-resistant bacteria.68 For irritable bowel syndrome69, spastic colon, gastritis, heartburn, indigestion, nausea, and vomiting use one drop of peppermint M. ×piperita essential oil in one-half glass of warm water, stir thoroughly, and sip slowly. You can also place one drop in honey or milk on a lactose tablet. Diffusing it will also provide benefits.

Peppermint M. ×piperita is rubefacient, stimulating capillary dilation causing skin redness when applied locally. It draws blood from deeper tissues and organs, and relieves congestion and inflammation. It is also a vasoconstrictor, causing constriction of blood vessels and a vasodilator, causing dilation of blood vessels. For bruises, rheumatism, and tennis elbow, apply as a compress. Peppermint M. ×piperita is an antispasmodic, relieving nervous irritability and reducing or preventing excessive involuntary muscular contractions and spasms. For dysmenorrhea71, alternate hot and cold compresses. The antispasmodic actions of peppermint M. ×piperita essential oil led researchers to study it for potential anti-seizure actions. An animal study found peppermint essential oil completely prevented induced seizures in mice. More research will have to be done to understand how this mechanism can be used safely for human applications.72

Household Uses Peppermint M. ×piperita is a well-known flavor. If you brush your teeth, chew gum, use mouthwash, or gargle you will know the cool flavor of peppermint. Peppermint flavoring is used extensively in many preparations. It is also a useful mosquito repellent and larvicidal73, and it is said that mice and rats dislike peppermint. An old method used to clear a building of rats was to block up their holes with rags soaked in peppermint M. ×piperita oil.

Essential Oil Monographs

than the recommended daily use, peppermint M. ×piperita oil has been known to cause allergic reactions in the mouth, neck, and throat. Anyone with a glucose-6-phosphate dehydrogenase (G6PD) deficiency should avoid peppermint oil via any administrative route as it may impact red blood cell activity. Glucose-6-phosphate dehydrogenase (G6PD) deficiency is a condition in which red blood cells break down when the body is exposed to certain drugs or the stress of infection. It is hereditary, so is passed down in families.75 76 Anyone with gastroesophageal reflux disease (GERD) should avoid peppermint essential oil orally (and potentially topically), as it may aggravate the condition.77 Topically for adults, use peppermint for a limited time only (i.e., no more than three consecutive weeks) and keep at a 1% dilution. Do not get it in your eyes. If you wipe your eye by mistake after handling peppermint M. ×piperita, flush copiously with cold water or milk. It will not cause permanent damage.
