Essential Oil Allergic Reaction: Symptoms, Treatments, and Prevention
Essential oils are currently the “cool kids” of the wellness scene, touted for health benefits ranging from relieving anxiety, fighting infections, easing headaches, and more.But if used improperly, essential oils can cause allergic reactions, among other adverse effects.Read on to learn how to spot symptoms of an allergic reaction to essential oils and tips for safely using this alternative treatment.These complex substances aren’t regulated by the Food and Drug Administration, and some of their health benefits are overstated.Allergic reactions range from mild to life-threatening, and they result in symptoms that usually affect your nose, lungs, throat, skin, stomach, sinuses, or ears.In addition to itchy, red rash, both types of contact dermatitis share other symptoms: dry, cracked, or scaly skin.welts that can vary in size and often repeatedly appear and fade Phototoxic reactions Some essential oils are photosensitive or phototoxic, which means that they can cause a serious reaction if you apply them topically and then expose your skin to the sun’s UV rays.Citrus essential oils, including lemon, lime, orange, and bergamot, are known to cause photosensitive reactions.blistering If you choose to use a photosensitive essential oil, avoid exposing your skin to UV rays for at least 12 hours.burning If you suspect that you’re having an allergic reaction to an essential oil, stop using it immediately.If you applied the oil topically, thoroughly wash the affected skin with gentle soap and cool water.If you accidentally swallowed an oil, immediately call the Poison Control hotline at 800-222-1222 and follow these precautions: Don’t try to induce vomiting.Keep the essential oil bottle on hand to help the emergency response team assess the situation.Although nearly 100 varieties of essential oil are commonly used, there isn’t a large body of comprehensive research on their potential for causing allergic reactions.Here are the steps for performing a patch test: Wash your forearm with mild, unscented soap, and pat the area dry.If you notice any rash, irritation, or discomfort during the 24 hours, remove the bandage and wash your skin thoroughly with gentle soap and water.However, a successful patch test doesn’t mean that you won’t develop an allergy or experience a reaction after future use.All essential oils degrade over time, but storing them in a cool place away from direct light can help slow down the process.If you notice that an oil has changed color, smell, or texture, it’s best to throw it away and buy a fresh bottle.We just don’t know for sure what is safe, so check with your healthcare provider and talk with a certified aromatherapist if you’re pregnant or breastfeeding. .

Safety Assessment of Rosmarinus officinalis (Rosemary)-Derived
The VCRP data obtained from the FDA in 2014,26 and data received in response to a survey of the maximum reported use concentration by category conducted by the Personal Care Products Council (Council)27,28 in 2013, indicating that 9 of the 10 ingredients included in this safety assessment are currently used in cosmetic formulations (Table 8).However, R officinalis (rosemary) leaf extract is reported to be used at up to 10% in body and hand products and 3% in eye shadow formulations and bath soaps and detergents.All of the ingredients named in this safety assessment are listed in the European Union inventory of cosmetic ingredients.33 Noncosmetic Rosmarinus officinalis L. is GRAS as a spice and as a natural seasoning and flavoring when the intended use is for human consumption (21CFR182.10) and for animal drugs, feed, and related products (21CFR582.10).It is also GRAS as an essential oil, oleoresin (solvent free), and natural extractive (including distillates) for human consumption (21CFR182.20) and for animal drugs, feed, and related products (21CFR582.20).According to The Official Journal of the European Union, extracts of rosemary contain several antioxidant compounds, and although the European Food Safety Authority (EFSA) was not able to establish an acceptable daily intake due to insufficient toxicological data, the EFSA considered the margin of safety was high enough to conclude that dietary exposure was not a concern.34 Extracts of rosemary are allowed in various food products at amounts of 30 to 1,000 mg/kg, expressed as the sum of carnosol and carnosic acid.Doses as high as 14.1 g/kg bw rosmarinus officinalis (rosemary) leaf extract were tested (5 days by gavage), and some studies were performed for up to 3 months (dietary) with doses of up to 400 mg/kg bw/d.8 Increases in absolute and relative liver-to-body weights were observed in many of the studies, independent of the extraction method; these changes were shown to be reversible, and no other signs of toxicity were observed.Oral administration of rosmarinus officinalis (rosemary) leaf oil with carbon tetrachloride, but not without, resulted in an increase in liver weights.41 Table 10.Anti-Inflammatory Effects Rosmarinus Officinalis (Rosemary) Leaf Extract Rosmarinus officinalis (rosemary) leaf extract has been shown to inhibit formaldehyde-induced plantar edema and 12-tetradecanoylphorbol-13-acetate (TPA)-induced and arachidonic acid-induced ear edema.43,44 In the formaldehyde-induced plantar edema study, groups of 6 male Balb/C mice were given an injection of 20 µL of 3% formaldehyde into the subplantar region of both hind paws.43 After 2 hours, one hind paw was treated with 10 µL of 12 mg/mL of an ethanol extract of R officinalis (rosemary) leaves topically, as an injection, or both.The TPA-induced ear edema study was conducted in groups of 10 male Balb/c mice.43 The effect of pretreatment with 10 to 1,000 µg/cm2 of an ethanol extract of R officinalis (rosemary) leaves at 30 minutes prior to induction of inflammation with 25 ng/cm2 TPA was evaluated.In a TPA-induced mouse ear edema study conducted in groups of 6 to 10 female CD-1 mice, a single dose of 20 µL acetone, 0.5 nmol TPA, or TPA and 0.04, 0.12, or 0.36 mg of a methanol extract of R officinalis (rosemary) leaves in 20 µL acetone was applied to one ear of each mouse.44 The mice were killed after 5 hours, and rosmarinus officinalis (rosemary) leaf extract inhibited TPA-induced inflammation by 17%, 75%, and 92%, respectively.In the arachidonic acid-induced mouse ear edema study, 0.02, 0.09, and 0.45 mg of a methanol extract of R officinalis (rosemary) leaves in 20 µL acetone was applied to groups of 10 female CD-1 mice at 30 minutes prior to treatment with 0.3 mg arachidonic acid in 20 µL acetone.44 The mice were killed after 1 hour.However, the high-dose group exhibited statistically significantly reduced absolute weights and organ to body weight ratios of testes and male accessory sex organs, diameters of seminiferous tubules and Leydig cell nuclei, height of epithelia of the epididymes and seminal vesicles, germinal and interstitial cell counts, levels of sex hormones, and sperm density and motility when compared to the controls.Effects on Estrogenic Activity Nonhuman Rosmarinus Officinalis (Rosemary) Leaf Extract Groups of seven or eight 6-week-old ovariectomized CD-1 mice were fed either a diet containing 2% of a methanol extract of R officinalis (rosemary) leaves or the basal diet.49 After 3 weeks, the animals were given an intraperitoneal injection of 0, 45, or 100 ng/mouse estradiol or estrone in 50 µL corn oil, once daily for 3 days.In in vivo studies in mice and rats, oils that were extracted by hydrodistillation induced statistically significant increases in chromosomal aberrations without gaps in a chromosomal aberration assay at 2,000 mg/kg bw, increases in micronucleated polychromatic erythrocytes (MNPCEs) in several micronucleus tests at 1,000 and 2,000 mg/kg bw, and increases in DNA damage in a comet assay at ≥300 mg/kg bw14,41; however, no genotoxic effects were seen in mice in a micronucleus test at 1,500 mg/kg bw/d with leaves extracted with absolute ethanol.41 A hydroalcoholic extract of rosemary was not genotoxic in a chromosomal aberration assay or a micronucleus test in rats.53 A mixture containing 19% R officinalis (rosemary) leaves, 71.5% St John’s wort, and 9.5% spirulina induced in mice statistically significant increases in MNPCEs at 760 and 1,520 mg/kg bw/d in a micronucleus test; in frequency of aneuploidy, percent polyploidy, and total percent aberrations with 760 and 1,520 mg/kg bw/d in a chromosomal aberration assay; and in frequency of banana-shaped, swollen acrosome, and triangular head sperm abnormalities and percent total spermatozoa abnormalities at 1,520 mg/kg bw/d in a spermatozoa abnormality assay.54 Table 11.Genotoxicity Studies View larger version Rosmarinus officinalis (rosemary) leaf extract was shown to have antimutagenic potential, in vitro, in an Ames test with Salmonella typhimurium and in Comet assays in a human hepatoma cell line.51 In vivo, in micronucleus assays, rosmarinus officinalis (rosemary) leaf extract did not decrease the number of MNPCEs induced in mice by a genotoxic agent.41.Carcinogenicity Effects on Tumor Promotion Topical application of methanol and double distilled water extracts of R officinalis (rosemary) leaves statistically significantly decreased skin tumors in mice; in these studies, 7,12-dimethylbenz[a]anthracene (DMBA) or benzo[a]pyrene (B(a)P) was used for initiation and TPA44 or croton oil55,56 was used for promotion (Table 12).Dietary administration of 1.0% R officinalis (rosemary) leaf extract decreased the incidence of palpable mammary tumors in rats caused by DMBA.57 Table 12.Most of the ingredients included in this review are extracts, essential oils, powders, or waters derived from a defined part of the R officinalis (rosemary) plant.However, rosmarinus officinalis (rosemary) leaf extract has higher concentrations of use reported, specifically, use at up to 10% in body and hand products and 3% in eye shadow formulations and bath soaps and detergents.Rosmarinus officinalis L. is composed of an array of constituents, primarily phenolic acids, flavonoids, monoterpenes, diterpenes, diterpenoids, and triterpenes.The principal antioxidative components of rosmarinus officinalis (rosemary) leaf extract are the phenolic diterpenes carnosol and carnosic acid.The actual amount of constituents present varies according to the stage of development, variety of plant, season harvested, origin of the leaves, and extraction method.A number of oral repeated-dose toxicity studies were performed in mice and in rats with R officinalis (rosemary) leaves extracted in a various solvents.Oral administration of rosmarinus officinalis (rosemary) leaf oil with carbon tetrachloride, but not without, resulted in an increase in liver weights.A high dose (500 mg/kg/d) of rosmarinus officinalis (rosemary) leave extract was a reproductive toxicant in a dietary study in male rats.In a study in gravid female Wistar rats, no statistically significant changes were observed after oral dosing with 26 mg/d of a 30% aq rosmarinus officinalis (rosemary) flower/leaf/stem extract during preimplantation or during organogenesis.In a dietary study in ovariectomized CD-1 mice, 2% of a methanol extract of R officinalis (rosemary) leaves inhibited the uterine response in a statistically significant manner.In vivo, in micronucleus assays, rosmarinus officinalis (rosemary) leaf extract did not decrease the number of MNPCEs induced by a genotoxic agent.Topical application of methanol and double distilled water extracts of rosmarinus officinalis (rosemary) leaves statistically significantly decreased skin tumors in mice; in these studies, DMBA or benzo[a]pyrene was used for initiation and TPA or croton oil was used for promotion.Dietary administration of 1.0% rosmarinus officinalis (rosemary) leaf extract decreased the incidence of palpable mammary tumors in rats caused by DMBA.In clinical testing, R officinalis (rosemary) leaves produced irritation (scores of +/−, +, or ++) in 44 of 234 patients with contact dermatitis or eczema.After further discussion, however, the Panel stated that because the deodorizing process is part of the preparation of food-grade rosmarinus officinalis (rosemary) extract, and because data are included in this safety assessment on some ingredients that were deodorized and no adverse effects were found, the Panel was not concerned with obtaining additional information on this process or the by-products that might form.The Panel stated that because the test participants were patients with eczematous skin, the report of irritation could not be interpreted for relevance to cosmetic use.Because these effects were observed only at very high concentrations, and because no statistically significant effects were reported in a study in rats dosed orally with 26 mg/d of a 30% aq extract of rosmarinus officinalis (rosemary) flower/leaf/stem extract, reproductive and developmental toxicity is not a concern with cosmetic use of R officinalis (rosemary)-derived ingredients, which are mostly used at very low concentrations.Furthermore, droplets/particles deposited in the nasopharyngeal or bronchial regions of the respiratory tract present no toxicological concerns based on the chemical and biological properties of these ingredients.A detailed discussion and summary of the Panel’s approach to evaluating incidental inhalation exposures to ingredients in cosmetic products is available at http://www.cir-safety.org/cir-findings.Unpublished sources cited in this report are available from the Executive Director, Cosmetic Ingredient Review, 1620 L Street, NW, Suite 1200, Washington, DC 20036, USA.All authors gave final approval and agree to be accountable for all aspects of work ensuring integrity and accuracy. .

Essential Oils for Skin Guide
And things get even more perplexing when you learn that the products that claim to be nice to your skin are filled with ingredients that are not, in fact, as gentle as they appear, but are actually incredibly irritating—like essential oils.Though they sound sweet and innocent, essential oils are highly concentrated essences that can cause skin damage and irritation.“With the rise of the natural skincare movement, more and more products are being formulated with essential oils, which are known irritants,” says dermatologist Joshua Zeichner, M.D., director of cosmetic and clinical research at Mount Sinai Hospital in New York City.“Tea tree oil, or TTO, has both antimicrobial and anti-inflammatory benefits, meaning it can calm inflammation in the skin and also reduce acne-causing bacteria,” says Dr. Zeichner.Luckily, products high in mint are usually easy to spot: They’ll often use words like “cooling,” “fresh,” “invigorating,” and “tingly,” which are basically code for “dermatologists hate this.” Still, double-check the ingredients list just to make sure you know what you’re slathering on.“We see a lot of citrus oils, like lemon and orange, in DIY skincare recipes, because they’re thought to brighten the skin and fade dark marks,” says Dr. Zeichner, “but in reality, they’re so acidic that they often just cause intense irritation, instead.” If your skin is especially prone to hyperpigmentation, that irritation can actually worsen or create even more darkness and scarring—i.e.Citrus oils (including orange, lime, lemon, grapefruit, and bergamot) have an extra special layer of risk to them: They can cause photoallergic reactions, meaning they react with the sun to cause phototoxic burns.Of course, your face cream with a bit of lemon or grapefruit oil at the bottom of the ingredients list isn’t necessarily going to lead to a blistering breakout.“It just means you have to be smart about patch-testing and recognizing adverse side effects, like itching, burning, or redness, so you can stop use immediately.” And if you do experience a reaction, immediately wash off the oil, slap on some 1 percent , and get yourself to a doctor’s office.The founder of Baie Botanique, Sophie Oliver, thinks adding the thorny flower to your routine might be better than receiving them.Try rubbing a couple of drops on your cuticles, take a nice big whiff, and get ready to have major heart eyes."It's known for its antibacterial, antimicrobial, and anti-inflammatory properties, that may make it useful for people with acne-prone, oily skin," says Blair Armstrong, Physicians Assistant in Dermatology and founder of GILDED."It's vitamin-rich, less irritating (which means it won't cause photosensitivity in sunlight), and has been shown to help regulate the amount of sebum produced by the skin," continues Armstrong.Blair Armstrong, physicians assistant in dermatology and founder of body skincare brand GILDED, explains: "It has sedative and anti-inflammatory effects but doesn't cause photosensitivity.".You probably know it's praised for improving brain function and decreasing stress from numerous studies, or maybe from one of the many Bath and Body Works aromatherapy lotions you own, but it has a couple of more tricks up its sleeve, and they all lead to your hair.Consider adding a drop or two of juniper berry oil to your moisturizer, as the evergreen extract is purifying and acts a natural skin toner.There have also been recent studies that suggest juniper berry oil has antioxidant, antibacterial, antiviral and antifungal activities, meaning it would be a great choice for anyone who suffers from acne, too.If frankincense immediately brings to mind the three kings and their treasured gifts to baby Jesus, well your association isn't entirely wrong.Frankincense, which has been heralded since Old Testament times for its healing properties, is the resin from Boswellia carterii, sacra, papyrifera, and frereana plants.Uses include scar fading, acne healing, and general enhanced glow and skin suppleness.If you're suffering from occasional cystic acne breakouts—which tend to be more bacterial-driven, versus hormonal–then a spot treatment with a dab of the antiseptic eucalyptus oil could be just the ticket.Chloe Metzger Deputy Beauty Director Chloe Metzger is the deputy beauty director at Cosmopolitan, obsessively writing about new makeup launches, the best hair products (curly girl here; whattup), and the skincare formulas that really work for every skin type ( follow her on Instagram to see behind-the-scenes pics of that magazine life).This content is created and maintained by a third party, and imported onto this page to help users provide their email addresses.
