The effect of the essential oils of lavender and rosemary on the human short-term memory

Abstract

The research results of the effect of essential oils on the human short-term image and numerical memory have been described. The study involved 79 secondary school students (34 boys and 45 girls) aged 13 to 17 years, residents of the Ukrainian metropolis. Participants were divided into three groups: the control group, ''Lavender" group, in which the lavender essential oil was sprayed, and ''Rosemary" group, in which the rosemary essential oil was sprayed. The statistically significant differences in productivity of the short-term memory of the participants of different groups have been found. Therefore, the essential oils of rosemary and lavender have significantly increased the image memory compared to the control. Inhalation of the rosemary essential oil increased the memorization of numbers, and inhalation of the lavender essential oil weakened this process.

Essential Oils as Treatment Strategy for Alzheimerʼs Disease: Current and Future Perspectives

“…[75] Memory performances in aged and young mice. Improved memory performances [76] Clinical trials Improved mood and cognitive performances [70,71,[76][77][78] AD: Alzheimerʼs disease, ICV: intra-cerebroventricular, Aβ: amyloid β neuroprotective potential of clove oil in ICV colchicine-induced memory impairment in rats has been reported in a study by Kumar et al [33]. Male SD rats were subjected to intraperitoneal injection of minocycline (25 and 50 mg/kg), clove oil (0.05 mL/kg and 0.1 mL/kg), and their combinations for 21 d. ICV colchicinetreated rats showed significant cognitive impairment in Morris water maze (MWM) test and showed an increase in AChE activity, oxidative stress, neuro-inflammation, and mitochondrial dysfunction as compared to control group.…”

“…The test group were administered EO (200,400,600 and 800 mg/ kg i. p.) daily for 7 d and improvement in memory performances were found in all test groups. Filiptsora et al [77] reported the effects of R. officinalis EO on the short-term and numerical memory in a study conducted in 79 school students (aged 13-17 y). The result showed positive results as evidenced by increased image and number memory compared to control groups.…”

Effect of one time coffee fragrance inhalation on working memory, mood, and salivary cortisol level in healthy young volunteers: a randomized placebo controlled trial

“…The calculations of the sample size were done with G-power 3.1.9.2 program (University of Dusseldorf, Dusseldorf, Germany). The effect size was calculated from the values of the mean of numbers of memorization between pre-and post-inhalation groups, based on a prior study 18 . Assuming the standard deviation (SD) between groups to be 1.8, alpha error probability of 5 %, a statistical power of 95 %, and a possible attrition (drop-outs) of 20 %, a total of 80 participants (40 per group) were chosen.…”

The effect of the rose essential oil aroma on university students’ learning and short-term memory: A randomized controlled trial

“…Aromatherapy is usually administered through inhalation because essential oils vaporize easily [1]. Many studies have shown the positive effects of pure essential oils on attention span [2], recall speed and quality [3], memory performance [4,5], short-term memory [6], image memory [7] in healthy individuals and on memory and moods in the cognitive disorders of dementia [8]. These effects occur due to the connections of the tractus olfactorius to the limbic system and the hypothalamus [9,10,11].…”
