About this blog

After seeing news articles say there was NO EVIDENCE that essential oils work for Ebola and hearing that the FDA has not approved any oils for any sort of disease, I decided to see what was out there and expose the essential oil industry. Instead, I found a mountain of peer reviewed studies for all kinds of serious diseases saying how well they work, even on Ebola! So, I decided to set up this blog to post a few studies a week to expose the real frauds and show the world what NO EVIDENCE looks like.
If you find value in my service, please donate to the blog since there is a cost to search and post these articles. I have waded through hundreds, if not thousands of difficult peer-reviewed articles to bring you those related to essential oils and ailments. I hope you find what you are looking for. I wish you great health, wealth and happiness!

Throughout the genetic and physiological evolution of microorganisms, the microbiological sciences have been expanding the introduction of new therapeutic trials against microbial diseases. Special attention has been paid to the bacterium Helicobacter pylori, which induces gastric infections capable of causing damage, ranging from acute and chronic gastritis to the development of gastric cancer and death. The use of compounds with natural origins has gained popularity in scientific research focused on drug innovation against H. pylori because of their broad flexibility and low toxicity. The aim of this study was to describe the use of natural products against H. pylori in order to clarify important parameters for related fields. The study demonstrated the vast therapeutic possibilities for compounds originating from natural sources and revealed the need for innovations from future investigations to expand the therapeutic arsenal in the fight against H. pylori infection.

Table 2. Anti-Helicobacter pyloriactivity of essential oils
Essential oils or scents are aromatic compounds found in different plant organs. They are also called volatile oils or ethereal oils, as they have a high degree of evaporation when exposed to air at room temperature; it is this feature that confers the significant odor to plants, both for attraction of pollinators and as insect and herbivore repellents [52]-[54]. These compounds have emerged in the medical field by presenting antimicrobial activities of extreme value with regards to drug action against pathogenic or opportunistic microorganisms, including antifungal and antibacterial action. Because the compounds have a complex constitution, the profile exerted against microorganisms is directly related to this feature; for example, the presence of terpenes, which are secondary metabolites of plants with interesting therapeutic properties, have been studied by the scientific community in recent years. The antimicrobial activity demonstrated by terpenes is attributed to their interference with the integrity and functioning of the cell membrane through induction of changes in membrane potential, loss of cytoplasmic material and inhibition of the respiratory chain [54],[55].
Studies with the aim to elucidate the anti-Helicobacter pylori profile presented by essential oils have been developed in recent years because of the need for further drug options in the treatment of disorders arising from this type of infection. This fact is justified by the increased number of strains resistant to the standard drug therapy used in clinical practice, such as clarithromycin, the drug most frequently used as a therapeutic agent, and the lack of an ideal drug regimen with 100% safe applicability [8].
To broaden the knowledge of the anti-H. pylori potential of essential garlic oil, Otha et al. [56] tested compounds isolated from crude oil and obtained MIC values ranging from 10 to 25 μg/mL.
Other antimicrobial profiles of essential oils are reported in the literature. For example, Kalputzakis et al. [57] observed antibacterial action against clinical H. pylori strains extracted from biopsies performed on adults and children from two species of plants from the Nepeta genus, Nepeta camphorata L. and Nepeta argolica ssp. dirphya, belonging to the Lamiaceae family. The profile established by the essential oils of the two species was shown to be relevant, with minimum inhibitory concentrations (MIC) of 128 and 64 μg/mL for N. camphorata and N. argolica ssp. dirphya, respectively. Four compounds of the two species were also isolated and tested, presenting MICs ranging from 16 to 64 μg/mL for the same strains. The results obtained from the isolated substances confirm that flavonoids are mainly responsible for the antimicrobial activity for products derived from plant sources, as these substances were characterized as flavonoid derivatives.
Ohno et al. [58] reported the action of 13 essential oils against strains of H. pylori from clinical and standard origin (ATCC). The study found activity against all strains tested with oils extracted from Cupressus sempervirens, Juniperus communis Melaleuca alternifolia, Lippia citriodora, Ocimum basilicum, Mentha piperita, Origanum majorana, Eucalyptus globulus., Ravensara aromatica, Citrus limonum, Cymbopogon citratus, Rosmarinus officinalis and Lavandula latifolia. The same sensitivity profile was observed by Deriu et al. [59] in 2007, who investigated the activity of the essential oil of Myrtus communis L. against ten clinical isolates of Helicobacter pylori with a resistant profile for triple therapy with metronidazole, clarithromycin and levofloxacin.
The essential oil of Sicilian lemon (Citrus lemon Burm. Rutaceae) is classified as a potentially promising product against gastrointestinal diseases [60]. A study regarding its antimicrobial potential against Helicobacter pylori by Rozza et al. [61] revealed a minimum inhibitory concentration of 125 μg/mL. Furthermore, the authors performed a phytochemical analysis to identify the compounds present in the oil. Approximately 17 compounds were identified, of which 13 were identified by gas chromatography. The authors characterized monoterpene limonene as the major constituent of the essential oil, equivalent to approximately 70.75% of the total product. Moreover, the presence of β -pinene was also detected at a concentration of 13.19%. The antimicrobial profile of the two major isolated compounds resulted in MICs of 75 μg/mL and 500 μg/mL for limonene and β-pinene, respectively. Thus, the results were able to attribute limonene as the main compound responsible for the anti-Helicobacter pyloriactivity.


This review demonstrates the grandiosity of the use of compounds derived from natural products against Helicobacter pylori and denotes the need for scientific and technological expansion regarding these agents. Future work focused on promoting a therapeutic arsenal endowed with significant pharmacological actions and low toxicity and cumulative effects is required.

Suppressive Effects of Rosa Damascena Essential Oil on Naloxone- Precipitated Morphine Withdrawal Signs in Male Mice


This research was done to test the effect of Rosa damascena essential oil on withdrawal signs of naloxone-precipitated morphine in male mice. Morphine dependence was induced by injection (IP) three times daily at doses of 50, 50 and 75 mg/kg, respectively, for 3 days. On day 4, after the last administration of morphine, Rosa damascena essential oil was administered at different concentrations (5, 2 and 40%, IP) 30 min before administration of naloxone (5 mg/kg, IP). The following actions were taken as signs of withdrawal and records taken for jumping as a number and scores of 0 to 3 were given for incidences of grooming, teeth chattering, rearing, writing, diarrhea, wet dog shakes and climbing during a 30 min periodResults showed that different concentrations of Rosa damascena essential oil significantly reduced signs of morphine withdrawal compared to the control group in terms of number of jumps (p < 0.05 and p < 0.01), grooming, teeth chattering, rearing, climbing, wet dog shakes and writhing, but not for diarrhea (p < 0.05). In conclusion it seems that GABAergic activity induced by flavonoids from Rosa damascena essential oil can alleviate signs of morphine withdrawal, but further studies need to be done to better understand this mechanism. 
In conclusion, it seems that flavonoids of Rosa damascena essential oil with GABAergic activity can attenuate morphine withdrawal signs. But further studies need to be carried out to better understand this mechanism.

Neck Pain and Marjoram, Black pepper, Lavender and Peppermint

 2014 Oct;20(10):771-9. doi: 10.1089/acm.2013.0453. Epub 2014 Sep 5.

The effectiveness of essential oils for patients with neck pain: a randomized controlled study.


Abstract Objectives: To assess the efficacy of aromatic essential oils on neck pain.


Sixty participants with a history of neck pain and Neck Disability Index (NDI) score >10% were selected and randomly divided into control and experimental groups.


Motion analysis laboratory at Hungkuang University.


For the experimental group, the intervention included 3% concentration cream composed of four essential oils: marjoram, black pepper, lavender, and peppermint. For the control group, only an unscented cream was provided. For 4 weeks, all patients applied 2 g cream directly to the affected area daily after showering or bathing.


Assessment was performed by using a visual analogue scale (VAS), NDI, pressure pain threshold (PPT) evaluated with a pressure meter, and neck-joint range evaluated with Motion Analysis System (MAS).


A t-test statistical analysis by SPSS statistical software indicated that VAS scores improved significantly for both groups (p<0.05). In addition, the experimental group had improved pain tolerance in the left upper trapezius (mean±standard deviation, 2.96±2.54) and right upper trapezius (2.88±2.90) as measured by the PPT. According to the NDI, the experimental group also showed significant improvement (p=0.02). Comparison of MAS values before and after the intervention showed significant improvement in the 10 motion areas in the experimental group. This finding suggests that the experimental group had better results than the control group.


The essential oil cream developed in this study can be used to improve neck pain. This study appears to be the first to quantify this by using PPT and MAS.

ADDHD, Autism, Focus and Vertiver

"The results in this study taken together with results from previous studies suggest that breathing low doses of the volatile compounds from the roots of V. zizani- oides increases sympathetic nerve activity, which

maintains performance during the visual discrimination task."

"The present study thus provides the first experimental evidence to support the tradi- tional use of V. zizanioides roots to increase focus in humans."

The perennial grass Vetiveria zizanioides (vetiver) is mainly cultivated for its fragrant essential oil. Although the components of the oil and their biological activities have been studied extensively, the effect of the volatiles emitted from the roots of V. zizanioides on humans has so far remained unexplored. We investigated the effects of volatile compounds emitted from the cut roots of V. zi- zanioides (1.0 g, low-dose conditions; 30 g, high-dose conditions) on individuals during a visual display terminal task. Participants who breathed the volatile compounds emitted under low-dose conditions showed faster reaction times and stimulation of sympathetic nerve activity as measured by electrocardiography. These effects were not observed under high-dose conditions. The total amount of volatiles emitted during the experiment was 0.25 μg under low-dose conditions and 1.35 μg under high-dose conditions. These findings indicate that volatile compounds emitted from the roots of V. zizanioides under low-dose conditions may have helped subjects to maintain performance in visual discrimination tasks while
