Tematika

Essential oils (EOs) are very interesting natural products and among other qualities they possess various biological properties. The term biological comprises to all activities that these mixtures of volatile compounds (mainly mono- and sesquiterpenoids, phenylpropanoids, etc.) exert on humans. EOs are used for their therapeutic action, for flavouring, in perfumery, or as starting materials for the synthesis of other compounds. For therapeutic purposes they are administered as inhalations (e.g. eucalyptus oil), orally (e.g. peppermint oil) and transdermally (e.g. rosmary oil). Oils with a high phenol content, for instance thyme and clove, have antiseptic properties, whereas others are used as carrminatives. Oils showing antispasmodic activity, and much used in popular medicine, are those of melissa, peppermint, chamomile, fennel, caraway and orange. Furthermore, in traditional medicine, EOs are also well-known for their analeptic, antimicrobial, antinociceptive, antiphlogistic, antioxidative and sedative activities. All terpenoids easily enter the human body by oral absorption, penetration through the skin, or inhalation very often leading to measurable blood concentrations. The aim of this course is to introduce the most important medicinal plants containing essential oils and their medicinal role in the therapy and the clinical aromatherapy. We would like to highlight their appropriate use, their profiles, but to call students' attention to the cautions and contraindications of EOs, as well.
