Nepeta cataria L. grows spontaneously in certain regions of Romania, and based on specialised studies since 1977, it has been introduced into the culture as a medicinal species. Studies over time have also attributed food uses (spice) or plant protection (the phenomenon of allelopathy and repellent for some insects).
The plant has the morphological features characteristic of the Lamiaceae family and is the most representative species of this genus in our country. Through the biochemical analyses performed, the authors tried to highlight the influence of the pedo-climatic conditions and the chemotype on certain components.
Electron microscopy (SEM) provides information about the size, shape and structure of cells specialised in the secretion of volatile oil, in this case glandular trichomes. It also provides information about the formations on the epidermis of the leaves and how a stress factor can influence them (see page 310).
