What essential oil is good for allergy relief
Essential oils are not regulated by the FDA and do not own to meet any purity standards. When purchasing essential oils, glance for a supplier who either distills their own material or deals directly with reputable distillers and uses gas chromatography and mass spectrometry (GC/MS) to analyze the quality of the product.
When buying pure frankincense essential oil, check the label for its Latin name, Boswellia carterii or Boswellia sacra.
No other oils ingredients should be listed. If you see another oil, such as fractionated coconut oil, jojoba oil, or sweet almond oil, the frankincense is diluted and should not be used in a diffuser.
Essential oils should be packaged in a dark amber or cobalt bottle and stored out of sunlight.
Dosage and Preparation
There is no standard or recommended dose for frankincense essential oil.
When a drop or two is combined with a carrier oil (such as jojoba, sweet almond, or avocado oil), frankincense essential oil can be applied to the skin or added to baths in little amounts.
Frankincense essential oil can also be inhaled after sprinkling a drop or two of the oil onto a cloth or tissue, or by using an aromatherapy diffuser or vaporizer.
In aromatherapy, several other essential oils are often used in combination with frankincense.
While preliminary research suggests that frankincense essential oil may offer certain health benefits, there is currently a lack of research testing the health effects of frankincense oil. A component in frankincense, boswellic acid, has been studied for its anti-inflammatory and anti-tumor properties. Here's a glance at the science.
Laboratory research on human cells indicates that frankincense essential oil may possess immune-stimulating and cancer-fighting properties that could aid in the protection against breast cancer and pancreatic cancer. However, it's significant to note that these studies were conducted in a lab (and not in people) and didn't test the aromatherapeutic use of frankincense oil.
More research is needed.
A combination of essential oils including frankincense oil may assist sleep in people with cancer, according to a study published in Complementary Therapies in Clinical Practice in For the study, people with cancer were given personal inhaler devices containing essential oils.
Of those who used the device, 64% had an improvement of at least one point on the sleep scale. One essential oil mix found effective included frankincense (Boswellia carterii), mandarin (Citrus reticulata), and lavender (Lavandula angustifolia).
Frankincense appears to own anti-inflammatory properties and several studies own examined its use for osteoarthritis and knee pain.
One review of published studies found Boswellia serrata extract shows clinically significant pain reduction for short-term use. However, studies showing its efficacy for long-term pain reduction are lacking.
I own type 2 diabetes. Can frankincense essential oil lower blood sugar?
Despite its purported use as an anti-diabetic agent, a placebo-controlled trial published in the Journal of Evidence-Based Integrative Medicine in found frankincense essential oil did not own any significant blood sugar lowering effects over a placebo.
Is it safe to ingest frankincense essential oil?
While some essential oil companies recommend ingesting frankincense essential oil for a wide variety of health ailments, there is no evidence to support its safety or efficacy.
If you select to ingest essential oils, be certain you are using pure oils and follow the manufacturer's directions carefully and discuss it further with your doctor.

Essential oils (EOs) are complicated volatile substances extracted from plants, and used in food, cosmetic, and perfume industries. They own gained the attention of the medical community for their biologically athletic effects and therapeutic potential for numerous illnesses.
In addition, EOs are also experiencing a tremendous growth in aromatherapy and home use for their reported health benefits. EOs are well-known allergens and photosensitizers; however, there is a paucity of data on the dermal exposure of essential oil use in the United States. In addition, the production and use of EOs is not currently standardized or regulated and may pose an occupational hazard for those with shut and repeated contact with EOs. With increasing popularity of essential oil consumption, clinicians can expect to come across more cases of cutaneous and systemic reactions to these complicated substances. This review provides the most updated and relevant scientific information related essential oil use, primarily pertaining to cutaneous involvement.
EOs are secondary metabolites found in plants.
They are derived from plant material, such as leaves, stems, flowers, bark, and roots. Common methods used to extract the components include steam distillation, or mechanical expression; oils produced with the aid of chemical solvents are not considered true EOs. The major chemical composition of EOs includes terpenes, esters, aldehydes, ketones, alcohols, phenols, and oxides. A given essential oil contains varying amounts of each of these compounds, which imparts a specific perfume and determines its therapeutic characteristics.
In contrast, a perfume is chemically made to mimic the smell of a plant or flower.
EOs can be divided into two main distinct biosynthetic origins: The terpenes and terpenoids, and the aromatic and aliphatic components. There is grand interest in the main biologically athletic component of EOs — terpenes and terpenoids. Terpenes are a large and diverse class of organic compounds that consist of five-carbon bases. Some terpenes, such as the diterpenes, are the building blocks for biologically athletic compounds such as retinol, retinal, and taxol. Diterpenoids own antioxidant, antimicrobial, anticancer, anti-inflammatory, wound healing, antihypertensive, analgesic, and anxiolytic activities.
APPLICATIONS OF EOS
Currently, of the approximately EOs that own been described, are commercially important[8,9].
The use of EOs is common in food flavoring, perfume, and cosmetic industries. The United States Food and Drug istration has classified most EOs as “generally recognized as safe” at specified concentration limits.
EOs comprise the key ingredient in aromatherapy, which is rapidly growing in popularity worldwide. Numerous spas, massage therapists, and practitioners of alternative medicine provide aromatherapy.
The most commonly used EOs in aromatherapy include patchouli, cedarwood, lavender, tea tree oil, along with citrus-scented oils such as bergamot, lemon, and orange oils (Table 1). The oils are generally applied to the skin, but can also be given orally, by inhalation, or by diffusion through the air. Currently, aromatherapy products do not need approval by the FDA.
Little is known about consumption habits and exposure to EOs, especially in the United States.
The most comprehensive study of usage patterns was a study, which focused on the 12 most types of EOs among participants in France. Information about types of EOs used, skin areas exposed, frequencies and quantities were collected. Lavender (Lavanda) species are the most used EOs among both females and males, followed by Eucalyptus oil (Table 2). The study notably pointed out the increased prevalence of female users for almost every types of Eos. In addition, females tend to apply EOs on their face and neck, while males applied the products on the chest.
EOs are composed of numerous biologically athletic molecules, which may own promising therapeutic benefits in numerous diseases and ailments.
EOs own been recognized for their antibacterial, antiviral, antifungal, and insecticidal properties, which led to their acceptance and wide-spread use in the food industry. Pre-clinical studies own shown that in addition to aforementioned properties, EOs also protest potent anti-inflammatory, and antioxidant activity. Because of the grand number and variety of constituents, EOs do not own specific cellular targets. They exert their cytotoxic effects through disruptions in the structure and functions of key intracellular lipids and proteins. In eukaryotic cells, EOs can change the fluidity of membranes, which become abnormally permeable resulting in leakage of radicals, cytochrome C, calcium ions and proteins.
Permeabilization of outer and inner mitochondrial membranes leads to cell death through apoptosis and necrosis. Similar cytotoxic effects were observed in vitro in numerous gram positive and gram negative bacteria of relevance to the food industry including S. aureus and E. coli.
Bottom of form
Of every the EOs, tea tree oil (TTO) is arguably the most recognized and investigated compound in dermatology. Numerous studies own demonstrated its tolerability and efficacy and against P.
acnes. A singe-blind randomized controlled trial (RCT) in patients showed that 5% TTO gel has a comparable efficacy to that 5% benzoyl peroxide lotion. In , a double-blind RCT was performed in 60 patients with mild to moderate facial acne vulgaris. A significant difference between TTO gel and placebo was observed based on decreases in entire lesion counts and acne severity index scores. Most recently, the results of a phase II pilot study assessing tea tree oil for the treatment of mild to moderate acne further demonstrated its efficacy, and favorable side-effect profile.
No serious adverse events were reported in this study and side effects were limited to self-resolving peeling, dryness and scaling. In addition, tea tree oil has shown promising results for other common dermatologic ailments such as seborrheic dermatitis. A single-blind parallel controlled trial of patients with mild to moderate dandruff showed that the use of 5% TTO shampoo showed 41% improvement in dandruff, as measured by quadrant-area-severity score, compared with 11% in the placebo group (P < ).
EOs own also been studied for the treatment of alopecia areata.
A double-blind RCT involving 86 patients showed that a mixture of thyme, rosemary, lavender, and cedarwood EOs massaged into patients’ scalps produced significant improvement when compared with the carrier oils alone (improvement in 54% and 21% of patients, respectively, P = ). The efficacy of the treatment was evaluated at initial assessment and 3 and 7 mo after treatment by dermatologists’ visual scoring of photographs and a computerized analysis of traced areas of alopecia.
However, the study had limited external validity, as the extent and severity of the alopecia areata in the subjects were not mentioned. At this time, there are no further clinical trials using EOs for alopecia areata.
There is little doubt that EOs may own grand relevance to the field of dermatology, and more studies should be performed given every of their in vitro findings. Further work on the antimicrobial, antiviral and antifungal effects of EOs may own immense potential in the treatment of dermatological diseases. Indeed, a study showed that a combination of TTO with iodine was superior to iodine alone in the treatment of molluscum contagiosum virus in 53 children.
Moreover, EOs may own benefits in other cutaneous maladies, such as hyperpigmentation. The efficacy of α-bisabolol, a terpene derivative of the essential oil of Matricaria chamomilla, exerts an inhibitory effect on melanogenesis. In a study, α-bisabolol was evaluated in an 8-wk clinical trial of 28 Asian females, and led to a significant decrease in hyperpigmentation.
While safety testing on EOs has shown minimal adverse effects, the use of EOs still poses risks and allergic responses that clinicians should be aware of.
Under normal conditions of established use, most oils appear to own a excellent safety profile. The majority of adverse events are mild, but serious toxic reactions from some EOs own been observed, including abortions or abnormalities in pregnancy, neurotoxicity manifesting as seizures or retardation of baby development, bronchial hyperreactivity, and hepatotoxicity.
Accidental ingestion by young children has occasionally proved fatal. Repeated exposure to topical lavender and tea tree oils was associated with the development of prepubertal gynecomastia in a case-series of 3 subjects. This outcome was reversible upon discontinuation of the oils, and was attributed to the mild estrogenic and anti-androgenic activities of lavender and tea tree oils.
Notably, the majority of adverse effects of EOs are cutaneous in nature. The field of dermatology has encountered an increase in the frequency of allergic reactions to EOs, likely secondary to the growing popularity of topical use of EOs.
EOs are known sensitizers, and there is extensive evidence linking them to cases of contact allergy and allergic contact dermatitis[34,35]. One case of airborne contact dermatitis secondary to sensitization after inhaled aromatherapy has also been described. As EOs age, they are often oxidized so their chemical composition changes, and may become more allergenic or prone to irritation.
The most common allergens are ylang-ylang oils, lemongrass oil, jasmine absolute, sandalwood oil, and clove oil. However, in clinical practice, it may be hard to identify specific EOs in numerous cases. For example, in aromatherapy, the practitioner commonly uses undefined mixtures of EOs without specifying the plant sources.
In addition, numerous EOs contain chemicals prone to causing sensitization, including limonene, linalool, citral, and cinnamyl alcohol (Table 3).
This is most commonly seen with citrus oils, such as bergamot, lemon, lime, and orange, which contain foucoramins, in addition to limonene, linalool, and citral. Linalool, a terpene derivative found in numerous EOs, is the most sensitizing components in numerous EOs. It is a fragrant chemical also found in lavender, ylang-ylang, and jasmine oils. Cinnamyl alcohol is found in patchouli oil. Factors influencing risk of photo-sensitization also include the quantity of product applied and the area of exposure.
This is significant as the major study determining exposure patterns of topical essential oil use found that females tend to apply to areas such as the face and neck, thus placing themselves at greater risk of photosensitive reactions.
NEED FOR FURTHER RESEARCH
Although it is well established that allergic contact dermatitis can result from essential oil use, the allergens in EOs are largely unknown.
Moreover, patch testing currently does not provide precise or particularly dependable information on EOs, as numerous EOs lack standardization in manufacturing and production. Finally, larger scale studies on exposure patterns are needed to reliably estimate the use of EOs. Numerous patients struggle with chronic cutaneous diseases and often wish to attempt to “natural” or “alternative” therapies, without being aware of the potential allergenic side effects.
The use of EOs, which are complicated volatile substances with strong odors, has endless been established in the perfume and cosmetic industries.
In addition, EOs own notable effects as antimicrobial agents, and are widely used in food industries. In recent times, EOs in the form of aromatherapy own experienced a resurgence in their popularity. They are notable for causing allergic and photosensitivity reactions, along with serious but rarely occurring side effects. More controlled clinical studies are needed to determine the benefits and risks of plant-derived products, especially EOs, in dermatology. This review describes historical and current results from scientific studies of essential oil components and highlights the areas in need of further research.

Possible Side Effects
Research is needed to assess the potential benefits and risks.
Ingesting frankincense essential oil may own toxic effects and isn't recommended, unless under a doctor's supervision.
In addition, some individuals may experience irritation or an allergic reaction when applying frankincense essential oil to the skin. A skin patch test should be done before using any new essential oil. Additionally, essential oils shouldn't be applied to skin undiluted.
Pregnant or nursing women and children should consult their health care providers before using essential oils.
It's also significant to note that self-treating a condition with frankincense essential oil and avoiding or delaying standard care may own serious consequences.
