ABSTRACT
Essential oils (EOs) contain diverse volatile as well as nonvolatile chemical components that interact differently with the container used for its storage. Due to its dual nature (volatile as well as nonvolatile) and stability concerns, it is essential to use a suitable dispenser to deliver the effective dose with the maximum therapeutic effects. The design and material used for inhalers must be compatible with the EO and its components because the EO in the vapor phase has different properties. It is important to develop a suitable device to produce dispersion under controlled conditions. A variety of conventional and advanced dispensing methods for EOs have been used so far; however, all methods have considerable advantages and disadvantages in context with their direct effect on the chemical profile of EOs. The materials used for the fabrication of these dispensers also have different levels of reactivity toward EO components. This chapter will give a brief overview of EO dispensing methods.
