The aim of this study was to find essential oils that have increased the oxytocin concentration in postmenopausal women. Fifteen postmenopausal women participated in this study and the effects of 10 different essential oils were investigated. The essential oils included rose otto, sweet orange, lavender, neroli, frankincense, jasmine absolute, ylang ylang, roman chamomile, clary sage, and Indian sandalwood. The subjects were exposed to the control first for 20 min, followed by exposure to an essential oil for 20 min. Each subject received exposure to only a single kind of essential oil per day. Saliva was collected four times for each patient: immediately before and immediately after control exposure, and immediately before and immediately after essential oil exposure. The oxytocin concentration in the saliva was measured using a competitive ELISA kit. The results showed that salivary oxytocin concentrations increased significantly more after exposure to lavender, neroli, jasmine absolute, roman chamomile, clary sage, and Indian sandalwood than after exposure to the control odor. The aroma of certain essential oils may elicit increased secretion of oxytocin in postmenopausal women. This study suggests that olfactory stimulation with any of a number of essential oils increases salivary oxytocin concentrations, which may inhibit aging-induced reduction in muscle mass and function in women.
本研究旨在寻找能增加绝经后妇女催产素浓度的精油。15 名绝经后妇女参与了这项研究，研究了 10 种不同精油的作用。这些精油包括玫瑰奥图、甜橙、薰衣草、橙花、乳香、茉莉净油、依兰依兰、罗马洋甘菊、快乐鼠尾草和印度檀香。受试者首先接触对照物 20 分钟，然后接触精油 20 分钟。每位受试者每天只接受一种精油的暴露。每位患者采集 4 次唾液：接触对照物前和接触对照物后立即采集，接触精油前和接触精油后立即采集。使用竞争性 ELISA 试剂盒测量唾液中的催产素浓度。结果表明，与接触对照气味相比，接触薰衣草、橙花、茉莉净油、罗马洋甘菊、快乐鼠尾草和印度檀香后，唾液中的催产素浓度明显升高。某些精油的香气可能会促使绝经后妇女分泌更多的催产素。本研究表明，用多种精油中的任何一种进行嗅觉刺激都会增加唾液中的催产素浓度，这可能抑制女性因衰老导致的肌肉质量和功能下降。
