Introduction to Essential Oils and Their Uses
Essential oils, aromatic volatile compounds extracted from plants, have a rich history spanning millennia. Their use extends far beyond simple fragrance; they’ve played significant roles in traditional medicine, religious ceremonies, and even everyday life across diverse cultures. Understanding their extraction methods and the properties of common oils provides a foundation for appreciating their versatility and potential benefits.Essential oils are concentrated hydrophobic liquids containing volatile aromatic compounds from various parts of plants, including flowers, leaves, bark, roots, and seeds.
These compounds, often terpenes and their derivatives, are responsible for the distinct aroma and therapeutic properties associated with each oil.
Methods of Essential Oil Extraction
Several methods exist for extracting essential oils, each impacting the final product’s quality and composition. The most common techniques include steam distillation, expression (cold-pressing), and solvent extraction. Steam distillation involves passing steam through plant material to volatilize the aromatic compounds, which are then condensed and collected.
