“…Generally speaking, the users themselves commonly use the following terminology connected with this specific usage of HP: “to calm the mind and positively enhance the mood” or refer to them as “nerve tranquilizers” or “nerve tonics”. In this sense, a worldwide usage of Kava-kava ( Piper methysticum ), St. John’s wort ( H. perforatum ), passion flower ( Passiflora incarnata ), valerian ( V. officinalis ) and gingko ( Ginkgo biloba ) is reported, while Galphimia glauca and chamomile ( M. recutita ) are used in the Mexican traditional medicine, Astragalus membranaceus , in the Korean ethnomedicine, as well as Centella asiatica and brahmi ( Bacopamon nieri ) among the people of India (Venkanna Rao et al, 2011). On the Balkan Peninsula, amongst the people of Serbia, several publications indicated that the usage of HP still exists and that, most certainly, it is not forgotten or completely replaced by standard drugs (Jarić et al, 2015, Zlatković et al, 2014, Šavikin et al, 2013, Jarić et al, 2007).…”
