The concept of functional food is becoming increasingly popular, and today the food is not only intended to satisfy hunger and provide the necessary nutrients, but also to prevent certain diseases and improve the physical and mental health of consumers. Among the most important representatives of functional foods are fruit and vegetables, tea, red wine, but also cocoa products with higher percentage of cocoa parts. Except for these natural, unmodified functional products, they can also be produced by enriching with bioactive ingredients that were not naturally present in the products, such as dietary fiber, vitamins, minerals, or plant species extracts. The aim of this paper is to point out the potential applications of medicinal plant species in the development of confectionery products, as a particularly attractive group of food products among all obtained age categories. For this purpose, it has been conducted an online survey of the population of the Republic of Croatia on knowledge, consumption and preferences related to medicinal plant species and on confectionery products enriched by the addition of medical plant species. The results of the questionnaire showed that the most consumed are chamomile, mint, elderberry, sage and nettle, mostly in the form of herbal infusions. Aiming to confirm the traditional application of certain plant species, recent researches are focused on examining their chemical composition and modes of action. Taking into account the great interest of the scientific community and the enviable knowledge and interest of the respondents for medicinal plant species, there is a great potential for expanding the range of food products with the addition of medical plant species.
