If this truly produced blood pressure decreases it is criminal that it hasn't been through full clinical testing and is a common protocol for blood pressure reduction rather than the current crop of drugs.
Abstract
OBJECTIVE:
Investigate
the effects of lavender oil on the central nervous system, autonomic
nervous system, and mood responses in humans after inhalation.
MATERIAL AND METHOD:
Twenty
healthy volunteers participated in the experiments. The present study
assessed autonomic parameters such as blood pressure, heart rate,
respiratory rate, and skin temperature to determine the arousal level of
the autonomic nervous system. In addition, subjects were asked to
estimate their mood responses such as feeling pleasant or unpleasant,
uncomfortable, sensuality, relaxation, or refreshing in order to assess
subjective behavioral arousal. Finally, electroencephalogram (EEG) was
recorded from 31 electrodes on the scalp according to the international
10 to 20 system, and EEG power spectra were calculated by Fast Fourier
Transform (FFT). Data was analyzed by comparing the effects of lavender
oil on physiological and mood states with sweet almond oil. These
assessments were measured before and after using paired t-test
statistical procedure.
RESULTS:
The
results revealed that lavender oil caused significant decreases of
blood pressure, heart rate, and skin temperature, which indicated a
decrease of autonomic arousal. In terms of mood responses, the subjects
in the lavender oil group categorized themselves as more active, fresher
relaxed than subjects just inhaling base oil. Compared with base oil,
lavender oil increased the power of theta (4-8 Hz) and alpha (8-13 Hz)
brain activities. The topographic map showed obviously more scattering
power in alpha range waves particularly in bilateral temporal and
central area.
CONCLUSION:
The findings provided evidence the relaxing effect of inhaling lavender oil.
