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.

The research results of the effect of essential oil of rosemary on the human short-term image and numerical memory have been described. The study involved 53 secondary school students (24 boys and 29 girls) aged 13-15 years, residents of the Ukrainian metropolis. Participants were divided into the control group 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 these two groups have been found, while sex differences in uniform groups were absent. Therefore, the essential oil of rosemary has significantly increased the image memory compared to the control. Inhalation of the rosemary essential oil increased the memorization of numbers as well.

The antibacterial properties of lipophilic, phenolic complexes and dry extract and sedative activity of dry extract obtained from Lamium album (white dead-nettle) herb have been investigated. It is established that white dead-nettle dry extract shows weak, and complexes extracted with chloroform and ethyl acetate-a strong antibacterial activity against S. aureus. As for P. aeruginosa highest activity shows the phenolic complex, for C. albicans-lipophilic complex of L. album herb. Dry extract of white dead-nettle herb shows psycho-sedative properties at a dose of 100 mg/kg, and the tendency to anti-hypoxic and reduce anxiety action at a dose of 10 mg/kg. The dry extract exhibits greater degree of the discovered properties than the reference drug Alora ®. Investigated complexes are promising targets for further study of pharmacological mechanisms of antibiotic, depressive and cerebroprotective activity.
