The menopausal transition is the time from the onset of menstrual changes until one year after the final menstrual period. During this phase, perimenopausal women experience a variety of health-related symptoms, which seemingly derive from declining level of estrogen secretion. It has long been recognized that some essential oils have the efficacy of alleviating menopausal symptoms. On the basis of this, it is possible that these essential oils have the potency to facilitate estrogen secretion in women. The present study investigated this possibility by examining if the olfactory exposure to the essential oil increase salivary estrogen concentration.
We tested the effect of ten essential oils; clary sage, frankincense, geranium, lavender, jasmine absolute, neroli, rose otto, ylang ylang, orange and roman chamomile, which are thought to relieve perimenopasal symptoms.
The results have shown increase of salivary estrogen concentration induced by exposure to geranium and rose otto compared to control odor.
Together with the previous studies, the present study may give support to the notion that olfactory exposure to some essential oils can influence salivary concentration of estrogen.
围绝经期过渡是指从月经变化开始至最后一次月经结束后一年的这段时间。在此阶段，围绝经期女性会经历各种与健康相关的症状，这些症状似乎源于雌激素分泌水平的下降。长期以来，人们已经认识到一些精油具有缓解更年期症状的功效。基于此，这些精油有可能促进女性雌激素的分泌。本研究通过检测嗅觉暴露于精油是否会增加唾液雌激素浓度来探究这种可能性。
我们测试了十种精油的效果，这些精油包括快乐鼠尾草、乳香、天竺葵、薰衣草、茉莉原精、橙花、玫瑰精油、依兰依兰、甜橙和罗马洋甘菊，它们被认为可以缓解围绝经期症状。
结果显示，与对照气味相比，暴露于天竺葵和玫瑰精油会导致唾液雌激素浓度升高。
与之前的研究一起，本研究可能支持这样一种观点，即嗅觉暴露于某些精油会影响唾液中雌激素的浓度。
