台灣紅檜精油嗅聞後對人體生理與感官之影響

Effects of Smelling the Chamaecyparis Formosensis Mastsum Essential Oil on Human Physiological and Sensory Evaluation

本研究係以嘉義大學之學生為對象，測量其嗅聞紅檜精油前後之血壓、脈搏變化情形，藉以了解紅檜精油對人體生理反應及感官評價之效應，所得結果可供精油使用者及類比方面之研究者參考，茲歸納如下：（1）嗅聞後人體之收縮壓降低5.39mmHg及舒張壓降低2.85mmHg，並達顯著差異，脈搏減緩0.34次／分，但嗅聞前後間並無顯著差異；（2）男生嗅聞後之收縮壓、舒張壓與女生嗅聞後之生理反應相同，脈搏男生無顯著差異，女生則有極明顯減緩趨勢；（3）男女嗅聞紅檜精油後對感官評價之感受強度，由小到大依次為花香味、喜歡程度、清爽度、舒適程度、味道溫和、自然味、木材味及不具刺滋味，就味道溫和、舒適程度及刺激味等三問項而言，男女學生感受不盡相同，男生評價均較女生為高；（4）居住地區不同及未曾使用香水、精油之經驗等，則嗅聞紅檜精油後沒有顯著差異；（5）男生生病與否，嗅聞紅檜精油後之生理反應無差異，但心理上之感官評價受影響，女生在生理期嗅聞紅檜精油後之生理反應與感官評價則無差異。 To clarify the effectiveness of the essential oil on human body physiological reaction and sensory evaluation, the students on the Lin Sun extention of National Chiayi University. The questionnaire was used, also, the blood pressure and the pulse were measured was smelled by the essential oil of Chamaecyparis Formosensis Mastsum. (Taiwan Red Cypress). As results, (1) After smelling Taiwan Red Cypress essential oil, the systolic and diastolic pressure of the students was significantly decreased about 5.39 and 2.85 mmHg, respectively. The pulse was increased about 0.34 times/min but showed no significant difference. (2) The systolic/diastolic pressure and the pulse change of the male students were of no significant difference after smelling the Taiwan Red Cypress essential oil. (3) After smelling the Taiwan Red Cypress essential oil, the extent to which the intensity is followings: flower odor, delight degree, fresh ratio, comfortable degree, gentle taste, natural taste, wood odor and without stimulate. In addition, the male students have higher evaluated on the factors of temperate, level of comfortable and unpleasant flavor than female students. (4) There is no significant difference on Taiwan Red Cypress essential oil among students, who live at the different area and who use perfume or not. (5) There is no significant difference between with/without illness students in physiological and psychological reaction, or between with/without students in female's menstrual.
