Tematika

Essential oils form a vital defense system for plants, helping to repel pests and attract pollinators. In human use, these complex compounds form the basis of aromatherapy, supporting physical and mental well-being. Due to their chemical diversity, they have significant antimicrobial and anti-inflammatory properties, making them promising active ingredients in modern drug research. The active ingredients of the oils enter the bloodstream through inhalation or absorption through the skin, and some of their components are even able to cross the blood-brain barrier. Their use in modern therapies is seen as a natural alternative. The course provides an opportunity to learn about the latest research findings.
