The emergence of multidrug-resistant bacteria and the subsequent growth in antibiotic resistance have made it imperative that new therapies and alternate treatments for infections be constantly developed. Essential oils (EOs) are widely used in the cosmetics, healthcare, traditional medicine, and food industries, therefore investigating their antibacterial properties could be one solution to this worldwide issue. Because of their varied chemical composition, the mechanism of action of EOs is complex. Respiratory tract diseases (RTDs) are bacterial infections and inflammation of the respiratory tract, and they can affect people of any age. Because of their low volatility, EOs can be inhaled directly into the lungs. They can help cure respiratory tract infections (RTIs) since they are antibacterial and anti-inflammatory. The goals of this review are to look at the most common respiratory diseases (both upper and lower) and to demonstrate how to test an EO's antibacterial activity by gaseous contact. We also talk about how EOs can reduce inflammation and how they affect bacterial cells. Results from ongoing human and animal trials are also presented. Also shown are patents that cover the management of RTIs by the use of EOs and their volatile components. The overarching purpose of this review was to demonstrate that EOs are useful in the treatment of RTDs, including RTIs, as antibacterial and anti-inflammatory drugs. This review aims to do two main things: (1) outline the most frequent disorders affecting the respiratory system, and (2) show that EOs have antibacterial effect in the vapour phase. Essential oils' anti-inflammatory and anti-bacterial properties are also covered. Human and animal research in real life are also included. Some volatile components of EOs have been shown to be effective in treating respiratory disorders, and this topic is the subject of a number of recently released patents
