Cardiorespiratory variables to fragrance stimulation by inhaling sweet marjoram essential oil.

<p>Panel A: Time courses of cardiorespiratory variables to fragrance stimulation by inhaling sweet marjoram essential oil. Panel B: Absolute difference relative to baseline in each variable data for each of the three separate 2-min duration (0–2, 2–4 and 4–6 min). * P < 0.05 vs. the control condition.</p

Cardiorespiratory variables during fragrance stimulation by inhalation sweet marjoram essential oil and post-inhalation recovery.

<p>Panel A: Time courses of mean BP, HR and VE to odor stimulation by inhaling sweet marjoram essential oil. Panel B: Percentage change from baseline in each variable data for each of the four separate 5-min duration (0–5, 5–10, 10–15 and15-20 min). * P < 0.05 and ** P < 0.01 vs. pre-inhalation baseline value.</p
