Essential oil is concentrated hydrophobic liquid containing chemical compounds from plant material such as, seeds, wood, flowers, leaves and resins. The liquid is extracted through several methods of distillation including steam, expression, solvent extraction and absolute extraction.
The chemical compounds found in the liquids assist plants in fighting off pests and diseases and protect the plants during droughts and extreme weather conditions. The use of essential oils for medical, spiritual and emotional support in humans dates back to ancient times. More recently, studies within the pharmaceutical and medical communities confirm that these same constituents can be beneficial to humans in fighting certain bacteria, fungi and viruses as well as supporting the brain in emotional responses, depression and anxiety.
