From ancient times, plants have been used by humans for food, fodder, fibre and medicinal purposes. Several plants were empirically considered as treatments for a large array of illness and medical conditions. Each community had specific natural remedies, based on the geographical area, environmental conditions and other factors. Thus, the use of plants can be considered as part of the intangible cultural heritage of each community. In the geographical area of today’s Romania, the ancient inhabitants, Dacians, had very good knowledge regarding the use of plants for medicinal purposes, as presented by several historical sources. The present work describes protocols for the extraction and purification of natural extracts, analytical characterisation, in vitro and in vivo evaluation of their potential applications as well as some practical examples of their application on selected Romanian native medicinal and aromatic plants. The presented results offer scientific support to their traditional use, suggesting in the same time some modern applications, for example in the nanotechnology field.
