紫苏植株香气对人体生理和心理健康的影响

Physiological and Psychological Response of Perilla frutescens to human health

摘要: 选取紫苏Perilla frutescens 作为研究材料，定量研究其挥发物对人体身心健康的影响：征集26 名在校大学生和研究生（平均年龄24±1.57 岁）志愿者，进行嗅闻紫苏的实验，对比分析闻香前后紫苏植株挥发物对人体生理和心理健康的影响，志愿者在房间中嗅闻紫苏0.5 h，其生理指标用脑电波（α波、β波、θ波）、血压（收缩压、舒张压）进行评估，心理指标用POMS 量表评估。结果发现，闻香0.5 h 后，志愿者的α波升高，β波和θ波下降，收缩压显著降低，情绪状态总估价（TMD）得分下降；此外，约81%的志愿者认为紫苏香气对自己有一定的积极作用。研究结果表明，嗅闻紫苏一段时间后可以使大学生精神放松并减少消极情绪。

Abstract: On 12th-14th June 2020, 26 volunteers with mean age of 24±1.57 years were selected for experiment of sniffing potted Perilla frutescens ina room for half an hour. Physiological parameters were assessed by brain waves and blood pressure, and psychological parameters were assessed bythe profile of mood states. The results showed that alpha waves increased, beta and theta waves decreased, systolic pressure decreased significantly,and total mood disturbance of volunteers decreased after sniffing. Besides, about 81% of the volunteers agreed that sniffing P. frutescens had positiveeffects on themselves.
