草药来源的精油广泛用于治疗上呼吸道和下呼吸道疾病，主要是由于其抗菌和抗病毒作用。薄荷脑是薄荷（Mentha）精油的主要成分，具有抗痉挛活性，可改善肺功能。在一项随机实验中，106名健康参与者接受了雾化薄荷、桉树或迷迭香精油15分钟或不接受治疗（对照）。没有精油对测量的肺活量变量（用力肺活量，呼气峰流量，第一秒用力吹出的空气体积与用力肺活量的比值）有影响。参与者对精油效果的期望并不影响他们的客观表现，但是，他们预测了感知（主观）变化。感知的变化和测量的变化之间没有联系。总之，吸入迷迭香、薄荷和桉树精油对肺活量测定的主观（感知）影响至少部分由预期介导。
Essential oils of herbal origin are widely used in the treatment of diseases of the upper and lower respiratory tract primarily due to their antibacterial and antiviral effects. Menthol, the major component of the essential oil of mint (Mentha) species, exhibits antispasmodic activity, which might result in improved lung function. In a randomized experiment, 106 healthy participants received nebulized peppermint, eucalyptus, or rosemary essential oil for 15 min or no treatment (control). None of the essential oils had an impact on the measured spirometric variables (forced vital capacity, peak expiratory flow, the ratio of the volume of air forcibly blown out in the first second to forced vital capacity). Participants' expectations regarding the effects of essential oils did not affect their objective performance, however, they predicted perceived (subjective) changes. Perceived and measured changes were not connected with each other. In conclusion, inhaled rosemary, peppermint, and eucalyptus essential oils' subjective (perceived) effect on spirometry is mediated at least partly by expectations.
