Introduction
Essential oil (EO) of Nepeta cataría L. is well-known as an aphrodisiac first of all [7]. It was revealed as a spasmolytic preparation as well [6]. Being concentrated in the air of 1 mg/m3 it reduces personal anxiety, improves general condition, mood, work capacity, vivacity and attentiveness [5].
Important task is to minimize body burden during aromatherapy due to reduction of the EO concentration in the air. It particularly concerns elderly people. But at the same time aromatherapy effect is impossible to the full.
Research objective is to investigate Nepeta cataría L. EO effect breathing it in low concentration on some functions of human central nervous system and cardiovascular system to find out if it does for aromatherapy.
Objects and methods
Researches were carried out in a group of 20 people, mainly women aged at 50-80 years old. The same by composition and number group was used as a control variant. Tested people of a control group were in rest listening to psychorelaxing record for 20 minutes. Experimental group were placed in the same room during the same time listening the same psychorelaxing record but breathing evaporated EO of Nepeta cataría L. till the final concentration in the air of 0,1 mg/m . Tests were conducted before and after procedures.
To assess procedure effect on cardiovascular system we measured heart rate (HR), systolic (BPS) and diastolic (BPD) blood pressure (BP).
Correction task, WAM test (well-being, activity, mood) and scale of anxiety and depression were applied to rate EO effect on nervous system [1,3,4].
Results were processed statistically due to paired test t-criterion by Student [2].
Results and discussion
According to parameters of WAM test experimental and control groups didn't have any reliable difference initially (table 1).
After psychorelaxation session (control) psychoemotional condition of tested people held on the same level.
After aromapsychorelaxation session (experiment) reliable differences weren't registered as well. Otherwise, aroma session with Nepeta cataría L. EO didn't influence on psychoemotional condition of tested people.

Psychoemotional condition of tested people from both groups (experimental and control) according to scale of anxiety and depression didn't present any reliable differences (table 2).
Session of psychorelaxation didn't reveal any reliable variations of test parameters in control group.
At the same time session of aroma psychorelaxation also didn't cause any reliable changes of test parameters in experimental group as well.

Rating of procedure effect on mental capacity by correction task (literal variant) found initial difference between parameters of control and experimental groups unreliable (table 3).
After psychorelaxation control group didn't show reliable changes of test parameters. While after aroma psychorelaxation in experimental group pace of work had reliable variations during the second minute of the test. At the same time a number of mistakes decreased reliably during both minutes of this test.

Initially (before test) reliable differences between values of BP and HR in both groups (control and experiment) weren't registered (table 4). At the same time either experimental or control group presented normal average value of BPS, BPD - optimum by JNC6, HR were normal as well.
After session of psychorelaxation parameters of BP and HR in control group didn't differ from initial data. But in experimental group session of aromarelaxation caused reliable reduction of BPS and HR.

Therefore Nepeta cataria L. EO breating it in low concentration didn't have any effect on psychoemotional condition of tested people. Though it stimulated mental capacity (reliable increasing of work rate during the second minute of the test). Moreover its accuracy level went up.
Consequently the principal result of Nepeta cataria L. EO effect on human higher nervous activity is stimulation of mental capacity. Light hypotensive and bradicardial influence of Nepeta cataria L. EO is considered as a positive property for its practical appliance, especially in work with people suffered from hypertension.
Pointed positive changes were registered in case of very low Nepeta cataria L. EO concentration in the air, that is 0,1 mg/m3.
Conclusions
1. Nepeta cataria L. EO didn't effect on psychoemotional condition of tested people breathing it in concentration 0,1 mg/m3.
2. During correctional task Nepeta cataria L. EO presented a light stimulative effect on mental capacity and increased its accuracy in the same concentration.
3. Nepeta cataria L. EO in concentration 0,1 mg/m possesses light hypotensive and bradicardial effect.

Introduction
Essential oil of Salvia sclarea L. is quite popular in aromatherapy [6]. It was found as an antidepressant [8], stress-limiting [9] and hypotensive remedy [5]. Salvia sclarea L. composition is rather close to Lavandula angustifolia: its main components are linalil acetate, linalool, geranyl acetate and terpineol [7]. To minimize body burden in terms of aromatherapy is an important task. It's possible due to reduction of EO content in the air. It
