Anxiolytics of natural origin II. Exotic plantsBiomedicine - Review

The article presented here is being published next to the previous article Anxiolytics of natural Origin I, which discussed plants originally occurring in the Czech Republic and plants cultivated othere. The second part summarizes knowledge concerning plants, which are neither original nor commonly cultivated in the Czech Republic. These are the species as follows: Atractylodes macrocephala, Bacopa monnieri, Centella asiatica, Citrus spp., Clitoria ternatea, Echium amoenum, Erythrina mulungu, Morinda citrifolia, Myristica fragrans, Ocimum sanctum, Panax spp., Passiflora incarnata, Piper methysticum, Sceletium tortuosum, Withania somnifera, Zingiber officinale and Ziziphus jujuba. These plants have been used in traditional medicine in areas of their original occurrence for the treatment of different disorders including anxiety and sleeplessness. These plants are currently subjected to a number of scientific studies, which frequently support the presence of medicinal effects. In some of these plants, only preliminary results are available and further research is needed including preclinical studies in animals and subsequently clinical trials. A further research of active substances of these plants and mechanism of their action on the organism can result in the development of new products for the treatment of anxiety disorders and further mental diseases. Mental problems currently widely occur in the population and thus, the research is promising. In tropical and sparingly explored regions, there are definitely a number of further plants with anxiolytic and sedative effects and thus, further ethno-botanical and ethno-pharmacological research of plants employed in traditional medicine in these regions is of importance. The protection of biodiversity, particularly in tropical rainforest inhabited by many plants and animals, which can serve as a source of still unknown biologically active substances is also of a great importance.

Keywords: anxiety disorders; anxiolytics; herbal remedy; traditional medicine
