Nano Encapsulation of An Essential Oil Transpire the Therapeutic Approach.

Essential oils are natural compounds extracted from plants that are volatile and sensitive to heat. Due to their therapeutic value, essential oils are now used in many industries, including the sanitary, cosmetic, agricultural, food, and pharmaceutical industries. These are complex mixtures of a wide range of volatile molecules, including phenol-derived aliphatic and aromatic compounds and terpenoids. Essential oils have been used medicinally since ancient times for their antibacterial, antifungal, antiviral, antiparasitic, insecticidal, sedative, antiinflammatory, and anaesthetic properties. However, essential oils come with inherent limitations; thus, nanoencapsulation is advocated as a remedy as it has the potential to enhance the stability, solubility, and effectiveness of formulations based on essential oils, all while preserving the therapeutic drug blood levels. It is not always viable to use essential oils independently in treatment due to several restrictions; however, nanodelivery technologies appear capable of overcoming these challenges. The therapeutic efficacy that is achieved can be affected by several factors, including the selection of the essential oil as well as the system of nanodelivery. Today, nanoencapsulation is capable of enabling the simultaneous delivery of multiple oils, providing synergistic effects, and facilitating the development of combinational therapies. Additionally, they may have potential applications in preserving food to prolong the shelf life of quickspoiling items and their fragrances. While there is already much research on the characterisation of EOs, this review evaluates the features of the nanoparticles employed for the delivery of essential oils and their impact on the functionality of nano-delivered essential oils and their beneficial uses.
