Oils derived from plants or plant products.
Unctuous combustible substances that are liquid or easily liquefiable on warming, and are soluble in ether but insoluble in water. Such substances, depending on their origin, are classified as animal, mineral, or vegetable oils. Depending on their behavior on heating, they are volatile or fixed. (Dorland, 28th ed)
Oils which evaporate readily. The volatile oils occur in aromatic plants, to which they give odor and other characteristics. Most volatile oils consist of a mixture of two or more TERPENES or of a mixture of an eleoptene (the more volatile constituent of a volatile oil) with a stearopten (the more solid constituent). The synonym essential oils refers to the essence of a plant, as its perfume or scent, and not to its indispensability.

Treatment of toenail onychomycosis with 2% butenafine and 5% Melaleuca alternifolia (tea tree) oil in cream. (1/678)

The prevalence of onychomycosis, a superficial fungal infection that destroys the entire nail unit, is rising, with no satisfactory cure. The objective of this randomized, double-blind, placebo-controlled study was to examine the clinical efficacy and tolerability of 2% butenafine hydrochloride and 5% Melaleuca alternifolia oil incorporated in a cream to manage toenail onychomycosis in a cohort. Sixty outpatients (39 M, 21 F) aged 18-80 years (mean 29.6) with 6-36 months duration of disease were randomized to two groups (40 and 20), active and placebo. After 16 weeks, 80% of patients using medicated cream were cured, as opposed to none in the placebo group. Four patients in the active treatment group experienced subjective mild inflammation without discontinuing treatment. During follow-up, no relapse occurred in cured patients and no improvement was seen in medication-resistant and placebo participants.  (+info)

Potentiation of GABAA receptors expressed in Xenopus oocytes by perfume and phytoncid. (2/678)

To study the effects of perfume and phytoncid on GABAA receptors, ionotropic GABAA receptors were expressed in Xenopus oocytes by injecting mRNAs that had been prepared from rat whole brain. Essential oil, perfume and such phytoncid as leaf alcohol, hinokitiol, pinene, eugenol, citronellol and citronellal potentiated the response in the presence of GABA at low concentrations (10 and 30 microM), possibly because they bound to the potentiation-site in GABAA receptors and increased the affinity of GABA to the receptors. Since it is known that the potentiation of GABAA receptors by benzodiazepine, barbiturate, steroids and anesthetics induces the anxiolytic, anticonvulsant and sedative activity or anesthetic effect, these results suggest the possibility that the intake of perfume or phytoncid through the lungs, the skin or the intestines modulates the neural transmission in the brain through ionotropic GABAA receptors and changes the frame of the human mind, as alcohol or tobacco does.  (+info)

Lack of effect of spearmint on lower oesophageal sphincter function and acid reflux in healthy volunteers. (3/678)

BACKGROUND: Spearmint is commonly used as an antispasmodic and as a flavouring in several medications including antacids. It can produce heartburn, presumably by lowering lower oesophageal sphincter (LES) tone, but the mechanism has not previously been objectively examined. AIM: To study the effect of spearmint on LES function, acid reflux and symptoms. METHODS: In healthy volunteers, a Dent Sleeve and a pH electrode were placed in the distal oesophagus. They were then given spearmint either in a flavouring (0.5 mg), or a high (500 mg) dose, or a placebo, using a double-blind randomized crossover design. LES pressure, oesophageal pH and symptoms were recorded for 30 min before and after administration. RESULTS: LES pressure was not affected by spearmint, either high dose (19.6 vs. 16.0 mmHg), flavouring dose (20.2 vs. 19.8 mmHg) or placebo (20.5 vs. 19.2 mmHg, all N.S.). There were no differences in reflux occurrence following high dose (mean = 0.65 vs. 0.85 episodes), low dose (0.4 vs. 0.5 episodes) or placebo (0.7 vs. 1.10 episodes, all N.S.). There was a significant increase in mean symptom scores following high-dose spearmint (0 vs. 0.35, P = 0.03), but not low dose (0 vs. 0.2) or placebo (0 vs. 0.5, both N.S.). One subject reported symptoms with placebo, one with low dose, and six with high dose; all without increased reflux episodes or decreased sphincter pressure. CONCLUSION: Spearmint has no effect on LES pressure or acid reflux. Flavouring doses of spearmint do not produce more symptoms than placebo while high doses can be associated with symptoms, presumably from direct mucosal irritation but not reflux.  (+info)

Suppression of cell cycle progression by flavonoids: dependence on the aryl hydrocarbon receptor. (4/678)

Some flavonoids are ligands of the aryl hydrocarbon receptor (AHR) and cause cell cycle arrest. The dependency of the cytostatic effects of five flavonoids (flavone, alpha-naphthoflavone, apigenin, 3'-methoxy-4'-nitroflavone and 2'-amino-3'-methoxyflavone) on a functional AHR was examined in AHR-containing rat hepatoma 5L cells and an AHR-deficient cell line (BP8) derived from the 5L line. The potent AHR ligand 2,3,7,8-tetrachlorodibenzo-p-dioxin (TCDD) was cytostatic to the 5L line due to the induction of a G(1) arrest and dramatically elevated steady-state levels of CYP1A1 mRNA. TCDD affected neither the proliferation nor CYP1A1 mRNA contents of BP8 cells. With the exception of apigenin, the flavonoids under study induced G(1) arrest in both 5L and BP8 cells when used at concentrations at which they functioned as AHR agonists, but not antagonists. Apigenin-treated 5L and BP8 cultures primarily arrested in G(2)/M. The AHR-containing murine hepatoma cell line 1c1c7 arrested following exposure to AHR agonist concentrations of flavone and alpha-naphthoflavone, but not TCDD. Unlike the G(1) arrest observed in 5L cultures, the latter two flavonoids caused principally G(2)/M arrest in 1c1c7 cells. These studies demonstrate that the cytostatic activities of flavonoids do not require the AHR and the site of checkpoint arrest with a specific flavonoid can vary with cell type.  (+info)

Elemene induces apoptosis and regulates expression of bcl-2 protein in human leukemia K562 cells. (5/678)

AIM: To study the antitumor action of elemene (Ele) and its mechanism. METHODS: Inhibition of proliferation was measured with a colorimetric 3-[4,5-dimethyl thiazol-2-yl]-2,5-diphenyltetrazolium bromide (MTT) assay. Morphological assessment of apoptosis was performed with fluorescence microscope. DNA fragmentation was assessed by agarose gel electrophoresis and flow cytometry. The levels of bcl-2 protein was measured with flow cytometry. RESULTS: Exposure of exponentially growing K562 cells to Ele 65-520 mumol. L-1 for 48 h resulted in growth arrest. The values of IC50 and 95% confidence limits were 220 (152-319) mumol.L-1. After treatment of K562 cells with Ele 130 mumol.L-1, marked morphological changes including "Apo bodies" reduction in volume were observed with fluorescence microscope. Agarose gel electrophoresis of DNA from cells treated with Ele for 48 h revealed "ladder" pattern. The levels of bcl-2 protein in K562 cells treated with Ele for 48 h were obviously decreased. CONCLUSION: Ele induces apoptosis of K562 cells, which is related with the down-regulation of bcl-2 protein in K562 cells.  (+info)

Antibacterial activity of Ocimum gratissimum L. essential oil. (6/678)

The essential oil (EO) of Ocimum gratissimum inhibited Staphylococcus aureus at a concentration of 0.75 mg/ml. The minimal inhibitory concentrations (MICs) for Shigella flexineri, Salmonella enteritidis, Escherichia coli, Klebsiella sp., and Proteus mirabilis were at concentrations ranging from 3 to 12 microg/ml. The endpoint was not reached for Pseudomonas aeruginosa (>=24 mg/ml). The MICs of the reference drugs used in this study were similar to those presented in other reports. The minimum bactericidal concentration of EO was within a twofold dilution of the MIC for this organism. The compound that showed antibacterial activity in the EO of O. gratissimum was identified as eugenol and structural findings were further supported by gas chromatography/mass spectra retention time data. The structure was supported by spectroscopic methods.  (+info)

Alteration of perceived fragrance of essential oils in relation to type of work: a simple screening test for efficacy of aroma. (7/678)

The perceptional change of fragrance of essential oils is described in relation to type of work, i.e. mental work, physical work and hearing environmental (natural) sounds. The essential oils examined in this study were ylang ylang, orange, geranium, cypress, bergamot, spearmint and juniper. In evaluating change in perception of a given aroma, a sensory test was employed in which the perception of fragrance was assessed by 13 contrasting pairs of adjectives. Scores were recorded after inhaling a fragrance before and after each type of work, and the statistical significance of the change of score for 13 impression descriptors was examined by Student's t-test for each type of work. It was confirmed that inhalation of essential oil caused a different subjective perception of fragrance depending on the type of work. For example, inhalation of cypress after physical work produced a much more favorable impression than before work, in contrast to orange, which produced an unfavorable impression after physical work when compared with that before work. For mental work, inhalation of juniper seemed to create a favorable impression after work, whereas geranium and orange both produced an unfavorable impression then. From these studies, together with those conducted previously with lavender, rosemary, linalool, peppermint, marjoram, cardamom, sandalwood, basil and lime, we thus concluded that the sensory test described here might serve not only as a screening test for efficacy of aroma but also as a categorized table for aroma samples which can act as a reference to each other.  (+info)

Differential induction of plant volatile biosynthesis in the lima bean by early and late intermediates of the octadecanoid-signaling pathway. (8/678)

Plants are able to respond to herbivore damage with de novo biosynthesis of an herbivore-characteristic blend of volatiles. The signal transduction initiating volatile biosynthesis may involve the activation of the octadecanoid pathway, as exemplified by the transient increase of endogenous jasmonic acid (JA) in leaves of lima bean (Phaseolus lunatus) after treatment with the macromolecular elicitor cellulysin. Within this pathway lima bean possesses at least two different biologically active signals that trigger different biosynthetic activities. Early intermediates of the pathway, especially 12-oxo-phytodienoic acid (PDA), are able to induce the biosynthesis of the diterpenoid-derived 4,8, 12-trimethyltrideca-1,3,7,11-tetraene. High concentrations of PDA result in more complex patterns of additional volatiles. JA, the last compound in the sequence, lacks the ability to induce diterpenoid-derived compounds, but is highly effective at triggering the biosynthesis of other volatiles. The phytotoxin coronatine and amino acid conjugates of linolenic acid (e.g. linolenoyl-L-glutamine) mimic the action of PDA, but coronatine does not increase the level of endogenous JA. The structural analog of coronatine, the isoleucine conjugate of 1-oxo-indanoyl-4-carboxylic acid, effectively mimics the action of JA, but does not increase the level of endogenous JA. The differential induction of volatiles resembles previous findings on signal transduction in mechanically stimulated tendrils of Bryonia dioica.  (+info)

Due to this fact, for hundreds of years, the East Asian medicine has treated various diseases and illnesses by stimulating certain foot points.. Their traditional medicine believes that body organs and systems are linked through meridians of energy that end in the feet, hands, ears and face. This healing tradition is known as reflexology..

Additional treatment with other plant essential oils did not significantly increase the high suppressive activity of cinnamon oil. Three different combinations of two different essential oils (fennel oil + origanum oil, fennel oil + thyme oil, origanum oil + thyme oil) significantly increased their antifungal activities against conidial germination compared to any single plant essential oil treatment. No additional increase in antifungal activity against conidial germination was found by mixing three or four plant essential oils (Fig. 3B)..

In fact, essential oils are generally not oils at all. They are concentrated liquids that are extracted from plants by various means that include simmering, steaming, and condensation. Due to these methods, it generally takes quite a bit of plant matter to equal a proportionally tiny amount of essential oils. Fortunately for ones pocketbook, essential oils are used only in minute quantities due to their level of concentration. As an example, some studies have shown that essential oil of oregano is such a powerful antiseptic that 1 part oregano oil to 4000 parts water will sterilize the water. It would be impossible to use on a human being undiluted, it would be far too powerful. Therefore, essential oils are always diluted in a carrier oil or water before use. Also, due to the concentration level, essential oils should never be taken by mouth without the supervision of a qualified herbalist who is familiar specifically with aromatherapy ...
Currently, there are no conclusive studies to demonstrate that essential oils can effectively treat ED in human males because much of the empirical research has been conducted in rodents rather than humans.. Essential oils can be toxic and should never be taken by mouth. Anyone considering using essential oils for ED should speak with a certified aromatherapist first. Essential oils should be diffused into the air or applied diluted in a carrier oil before applying to the skin. While essential oils can have adverse side effects, when used correctly, they are considered safe and could still have benefits for ED.. Aside from essential oils, there are other alternative treatments for ED that people can pursue. Talk to a healthcare provider for the best treatment as ED can be a symptom of other problems, such as diabetes, high blood pressure, atherosclerosis, or prostate issues.. ...
Only a handful of essential oils are known photosensitizers. As the NEJM quote above references, furocoumarins, also known as furanocoumarins, are one class of constituents found in essential oils. Furanocoumarins are found in many cold-pressed, or expressed, citrus essential oils like Bergamot, Lime, Lemon, and Grapefruit.. It may not be necessary to completely avoid these essential oils unless one is currently using medication that also contain phototoxic substances, like some antibiotics, NSAIDs, and heart medications. However, these phototoxic essential oils need to be diluted to keep the furanocoumarin levels very low to prevent a reaction. The International Fragrance Association (IFRA) based in Geneva, Switzerland helps our collective industries self-regulate and they offer specific guidelines for topical products (cosmetics, perfumes, massage oil) that contain phototoxic substances.. IFRA guidelines for select expressed essential oils:. ...
When essential oils contact the mucosa, they are absorbed to some degree at the initial point of contact, but much of the oil will be continually diluted by the mucous. Rapid absorption and constant dilution allow the oils to have a dramatic yet temporary effect, which explains why any sensation you have in the mouth or throat from essential oils taken internally is temporary. Because the muc. osa is designed to be protective, essential oils can be safely used internally.. The premise of all of these discussions is that essential oils could be harmful when taken internally. However, studies suggest just the opposite. Essential oils may actually be protective to the mucosa. Many studies show that essential oils can have a positive effect when there is a problem with the stomachs mucous membranes.* For example, limonene, found in citrus oils, was shown to help protect the stomach mucosa in a preclinical study.(3) This protective effect was shown without affecting normal stomach acid secretion, ...

Essential oils are natural products with a complex composition. Terpenes are the most common class of chemical compounds present in essential oils. Terpenes and the essential oils containing them are widely used and investigated by their pharmacological properties and permeation-enhancing ability. However, many terpenes and essential oils are sensitive to environmental conditions, undergoing volatilization and chemical degradation. In order to overcome the chemical instability of some isolated terpenes and essential oils, the encapsulation of these compounds in nanostructured systems (polymeric, lipidic, or molecular complexes) has been employed. In addition, nanoencapsulation can be of interest for pharmaceutical applications due to its capacity to improve the bioavailability and allow the controlled release of drugs. Topical drug administration is a convenient and non-invasive administration route for both local and systemic drug delivery. The present review focuses on describing the current status of

to name just a few ways I use essential oils every day.. Therapeutic-grade essential oils are above perfume-grade and food-grade oils. They have been studied for the assistance they can give in times of occasional pain, or occasional irregular bodily functions.. On www.pubmed.org, you can find thousands of studies involving the therapeutic benefits of essential oils. This is modern science catching up with what our ancient ancestors already knew: essential oils have complex organic chemistry that positively affects our own chemistry. They can help with supporting us in times of unusual strain, improve our memories, uplift our spirits and help us maintain our good health.. Doing your due diligence is crucial before buying essential oils. The range from purity to toxicity is vast. Because the essential oil industry is unregulated, a label may legally say contains essential oil of X if as little as 2 per cent of the bottle contains that oil.. The rest can be a combination of fillers, synthetic ...
Please, please STOP diffusing essential oils. Though they may be nice as an occasional air freshener, people are diffusing them non-stop in offices, schools, daycares, and homes. Essential oils are very potent. It is not good to be breathing them in for hours at a time. In medical school we learned to use eucalyptus and thyme oil as a short inhalation for sinus problems, putting a few drops into a steaming bowl of water while the patient puts their face over the bowl, breathing in deeply. But this is short use, never more than 5 minutes at the most. I know people are going to be mad at me because their MLM company has the purest, most organic form of oils that can heal the world. But essential oils are simply too strong to be used in the ubiquitous way they are being used now. Let me repeat, the quality of the orange oil doesnt matter. Orange oil is a strong degreaser. I have also seen Cedar oil and Lavender create strong allergic reactions. I dont think these oils are bad, they are simply ...

What is the real connection between terpenes and essential oils? Terpenes are aroma emitting phenols that are made by every plant, flower, and even some insects. One terpene you may recognize is Linalool. Lavender essential oil is primarily composed of Linalool. Chemists tell us that linalool makes you tired so Lavender essential oil makes you tired. Simple right? ESSENTIAL OILS VS. TERPENES Essential oils are the aromatic (and arguably medicinal) liquids obtained through the processing of certa
Essential oils are the subtle, cola tile liquids that are distilled from plants, shrubs, flowers, trees, bushes and seeds through an ancient and delicate process. Science is re-discovering the incredible healing power of essential oils and beginning to acknowledge their value.

Essential oils are extracted from the root, leaf, seed, bar, or flower of a tree or plant through a distillation process that separates the plants oil from its water compounds.. These aromatic oils are highly concentrated. For instance, it requires 150 pounds of lavender to extract one pound of essential lavender oil. This means the oil has 150 times the healing and protective properties as straight lavender.. The power of an essential oil lies in the size of its molecules. The molecules are small enough to penetrate our cells, and some can even cross the blood-brain barrier. Their minuscule size makes the molecules transdermal-they can pass through skin to enter the bloodstream.. Essential oils can also be assimilated through our olfactory system - our sense of smell - which is directly linked to the brain. When the smell receptors in our nose are stimulated by the oils, messages are sent to the nervous and limbic systems, influencing tranquility and mood.. ...
You probably know that essential oils are great ingredients to use for scalp conditions which they heal and nourish it. Therefore, they are excellent for hair growth. But if you want not to irritate or burn your scalp then a skin patch test is a must. In fact its an allergy test. Pure essential oils are highly concentrated and potent, so diluting them is a mandatory step. The way to do it is to add them to cold pressed carrier oils. This procedure also prevents the essential oils from evaporating since essential oils are not actually oils! Do the skin patch test to ...

According to David Stewart, PhD in The Chemistry of Essential Oils that sesquiterpenes delete bad information in cellular memory and are present in almost all essential oils. Dr. Stewart further states that they are the largest group of terpenes known naturally in the plant and animal kingdom.. Sesquiterpenes are larger than monoterpenes and are very viscous (less volatile) so they are often used as fixatives in the perfume industry. Viscous oils have a longer half-life and blend well with lighter, more volatile oils. Vetiver is a thicker essential oil. I generally mix about ¼ part carrier oil such as avocado oil or coconut oil with ¾ parts vetiver essential oil. This mixture is easier to drop out of the top of the bottle. If using a roller bottle, the oil is easier to flow.. Vetiver essential oil has a woodsy smell. For the first couple of years when I used it, I added at least 8-10 drops of orange essential oil to a 5 ml bottle of vetiver essential oil, along with the carrier oil. You can ...
Essential oils are potent volatile chemical compounds that can both heal and harm. In general, by adhering to aromatic oils on the recommended safe list, and following guidelines for dilution rates, we can minimise risks and enjoy the benefits. Let us not forget that there are other options aside from essential oils, that are part of aromatherapy. Hydrosols or floral waters are co-distillates from essential oils, and are often a safer option than essential oils, especially for infants and young children, and those with sensitive skin and complex medical conditions. Carrier oils and butters generally healing and nourishing, especially for skin conditions. Both hydrosols and fatty lipids (carrier oils and butters) may be better options compared to aromatic essential oils for children who have scent sensitivity or sensory processing issues.. Another aspect we need to consider is the desire to use strong antimicrobials to prevent illness/sickness, such as oregano, cinnamon, clove, and eucalyptus ...

Essential oils are used for a very wide range of emotional and physical wellness applications. They can be used a single oil at a time or in complex blends in one of three methods:. Inhalation.

Some ways to inhale essential oils are:. Diffusing for an entire room or home. (Ideally for oils that are energizing, antimicrobial, promoting memory and focus, relaxing. Example: lemon, lavender, rosemary.). Direct inhalation for personal benefits. This can be done with an inhaler or by directly smelling from the bottle. You can also put a drop or two in the palm of your hands and rub them together and then place your cupped hands over your nose and breathe in. I personally use this method for my headaches, sinuses, and when Im fatigued. (Ideally for personal benefit such as clear breathing, focus, anxiety, headaches, ...

This is an area where we exercise caution and make decisions based on in vitro, animal, and case-study research. Mothers arent lining up to test the toxicity of essential oils while pregnant, so the best course of action is to err on the side of caution and avoid or be cautious with essential oils that have shown an adverse effect in the available research. Virtually all essential oil constituents are of the molecular weight that they can cross the placenta. Always consult with your health professional before using essential oils during pregnancy and be aware of evidence-based lists (like the one found in Evidence-Based Essential Oil Therapy) of essential oils that re preferred during pregnancy. ...

The aim of this study was to investigate the antibacterial activity of some commercial essential oils, obtained from herbs and spices commonly used in cookery, against a panel of food-borne pathogenic and spoilage bacteria such as Stafilococcus aureus, Escherichia coli and Bacillus cereus. Eight essential oils were tested (dill oil, juniper oil, oregano oil, basil oil, thyme oil, rosemary oil, fir oil and clove oil) in different concentrations (1 l, 5 l și 10 l) using the agar diffusion technique. The results were compared with those of a commercial antibiotic gentamycin, which was used as a positive control at a constant concentration of 10 l. Some of the essential oils exhibited promising antibacterial effect as a diameter of zones of inhibition (21-33 mm) against the tested bacteria. The results indicate the potential efficacy of plant-based natural products such as essential oil of oregano, clove and thyme to control food-borne pathogenic and spoilage bacteria ...
Essential oils are naturally occurring, volatile aromatic compounds that are found in the seeds, bark, stems, roots, flowers, and other parts of plants. They are incredibly potent and fragrant giving plants their distinctive smell, such as a rose. They protect plants and play a role in plant pollination. For a long time, essential oils have aided in natural healing for humans and animals.. Volatile aromatic compounds are small organic molecules that tend to change quickly from their solid or liquid state to a gas at room temperature. Volatile- meaning they change state quickly. The physical and chemical properties of the volatile aromatic compounds that compose essential oils allow them to quickly move through the air and directly interact with the olfactory sensors in the nose, which is why essential oil is commonly used for aromatherapy for dogs..
