  • Patent number: 6495172
    Abstract: A method of using steam ironing of fabrics as a way of causing reduction of physiological and/or subjective reactivity to stress in a human is provided. The method includes the steps of providing a stress reducing composition comprising one or more of a volatile natural essential oil and water. The composition is adapted to not cause staining of fabrics. The method includes delivering the stress reducing composition into a liquid container of a steam iron and heating the steam iron. The method further includes releasing vapors of the stress reducing composition produced within the liquid container of the steam iron upon heating into ambient air. The method still further includes the step of causing reduction of physiological and/or subjective reactivity to stress in the human by one of more of transdermal ingestion or inhalation of the vapors by the human.
