HerbElixa DOO is a company founded in 2018 with an aim to develop and produce herbal products based on medicinal plants. Our main focus is development of products based on essential oils that can help in treatment of different health disorders and diseases. Also, we put special emphasize in development of products that can be used for eradication of microorganisms that are resistant to available therapies, such as Helicobacter pylori or Candida spp.

Essential oils, the basis of our products, are complex mixtures of numerous volatile compounds, obtained by hydrodistillation from aromatic medicinal plants. The structural diversity of these compounds enables them to work synergistically and through different mechanisms, thus it is practically impossible for bacteria microorganisms to develop resistance towards all of them at the same time. That is the main advantage of essential oils in comparison to other pure single compounds, beside their natural origin and low toxicity. Additionally, despite their great potential essential oils are very poorly exploited in pharmaceutical industry. For all these reasons, HerbElixa have chosen essential oils as basis of its products.

Our products are exclusively based on scientific results, primarily stemming from 10 and more years of research done by HerbElixa co-founders: three researchers and university professors that already built successful careers in science. All HerbElixa products represent innovation and are unique because they are produced by our own recipes and methodologies.

To obtain high quality of products we aim to control the whole process of manufacturing, from row plant material production to final product packaging and distribution. As raw material we use only plants cultivated by local farmers using organic agriculture methods, thus supporting rural transformation.


Co-founders of HerbElixa are Dr Nataša Simin, Dr Ivana Beara and Dr Marija Lesjak.
