Aromatherapy is a controlled usage of essential oils in order to balance a human organism. Essential oils were used by the ancient civilizations. French chemist Gattefosse is regarded as the founder of the modern approach and revival of beneficial usage of essential oils. There have been numerous studies on the efficiency of aromatherapy and most of them have shown that aromatherapy has a positive outcome. Some of the studies show us the efficiency aromatherapy has on breast cancer, hypertension, stress, newborn stomach cramps, hemiplegia shoulder cramps and many other conditions. The goal of this paper is to show and summarize the results of the studies that give us the results of aromatherapy usage in physiotherapeutic procedures, and based on the available literature, determine scientific soundness of essential oil usage in physiotherapy. Therefore, the typical studies done on this particular subject are displayed in this paper by using transparent studies which summarize and give us a critical overview of the results of numerous other studies. The results show us that, even though there are many studies on the efficiency of aromatherapy in different conditions and ailments, the existing literature gives us plenty of results of different methodologies when it comes to approaching aromatherapy that simply do not give us the opportunity of summarizing the results and coming to a concussion. We are missing additional studies which should be methodologically well structured and which are able give us credible proof that could prove to be a basis for a conclusion on beneficial effects and the consequences of this therapy.
