BACKGROUND
Green odor, a mixture of equal amounts of 2E-hexenal (leaf aldehyde) and 3Z-hexenol (leaf alcohol) has been demonstrated to have an anti-stress effect in rats. This study investigated whether or not green odor also has an anti-stress effect in humans.
METHODS
Changes in blood pressure, heart rate, and the skin temperature of a fingertip were observed after presenting green odor at a concentration of 0.03% or vehicle via inhalation through the nose for 10 min to eight healthy normotensive adults. We also assessed the pleasantness of green odor and its effect on mood states via assessment with the Profile of Mood States (POMS) questionnaire. Cardiovascular response to green odor and the vehicle were compared among 11 additional healthy adults by use of the cold pressor test.
RESULTS
Of 19 subjects, 15 (79%) reported that the green odor was pleasant. Green odor had no effect on blood pressure, heart rate, skin temperature, or POMS score under non-stressful conditions. In the second experiment, green odor attenuated cold pressor test-induced increases in systolic and diastolic blood pressure and facilitated the recovery of skin temperature.
CONCLUSION
These findings suggest that green odor has an anti-stress effect in healthy humans.
背景
已证实，由等量的 2E-己烯醛（叶醛）和 3Z-己烯醇（叶醇）混合而成的青草气味在大鼠身上具有抗应激作用。本研究旨在探究青草气味是否对人类也具有抗应激作用。
方法
通过鼻腔吸入浓度为 0.03%的青草气味或载体 10 分钟，观察 8 名健康血压正常的成年人血压、心率和指尖皮肤温度的变化。我们还通过使用心境状态问卷（POMS）评估青草气味的舒适度及其对情绪状态的影响。通过冷加压试验，在另外 11 名健康成年人中比较了青草气味和载体对心血管的影响。
结果
19 名受试者中，有 15 名（79%）报告说青草气味宜人。在非应激条件下，青草气味对血压、心率、皮肤温度或 POMS 评分均无影响。在第二项实验中，青草气味可减轻冷加压试验引起的收缩压和舒张压升高，并促进皮肤温度的恢复。
结论
这些发现表明，青草气味对健康人群具有抗应激作用。
