Essential oils are volatile and liquid aroma compounds from natural sources, usually plants. Essential oils are not oils in a strict sense, but often share with oils a poor solubility in water. Essential oils often have an odor and are therefore used in food flavoring and perfumery. Essential oils are usually prepared by fragrance extraction techniques such as distillation (including steam distillation), cold pressing, or extraction (maceration). Essential oils are distinguished from aroma oils (essential oils and aroma compounds in an oily solvent), infusions in a vegetable oil, absolutes, and concretes. Typically, essential oils are highly complex mixtures of often hundreds of individual aroma compounds.
Steam distillation is a special type of distillation (a separation process) for temperature sensitive materials like natural aromatic compounds.
Many organic compounds tend to decompose at high sustained temperatures. Separation by normal distillation would then not be an option, so water or steam is introduced into the distillation apparatus. By adding water or steam, the boiling points of the compounds are depressed, allowing them to evaporate at lower temperatures, preferably below the temperatures at which the deterioration of the material becomes appreciable. If the substances to be distilled are very sensitive to heat, steam distillation can also be combined with vacuum distillation. After distillation the vapors are condensed as usual, usually yielding a two-phase system of water and the organic compounds, allowing for simple separation.
Essential oils from the plants are evaporated with the steam that rises through the aromatic plant material.
Steam is then cooled to condense into liquid droplets.
The oil and water naturally separate, yielding essential oil and the water by-product called floral water or hydrolate.

Labdanum Oil Enhances Neural Activity
Labdanum is a single of those shrubs that makes ancient history an interesting as well as intriguing tale. Mediterranean sheep and goat herders ended up the first group to figure out what to do together with the sticky resin through the bushes. They collected the resin by combing the thighs and beards of goats that grazed on the cistus shrubs. They developed wooden rakes with a double row of wooden thongs to sweep the shrubs so the resin could be collected and then extracted.
The pharaohs had been the first group to use labdanum around the body. Almost all of them wore goat hair beards, which have been attached for the face with labdanum. The resin was also used to treat rheumatism, colds, and menstrual challenges. Some biblical scholars believe the holy incense mentioned within the bible (Ketoret) was actually labdanum.
The labdanum oil used in aromatherapy is actually an item of steam distilling the leaves and branches with the shrubs. Labdanum’s aroma is described as sweet, woody, and leathery with a dry musk as well as amber scent. The perfume market uses labdanum because it displays a number of scents that can be enhanced inside the perfume making process.
Most essential oils have antiseptic, antimicrobial, astringent, expectorant, balsamic, antitussive, emmenagogue, and tonic properties and labdanum is no various. The oil is used to treat diarrhea, dysentery, skin conditions, tumors, and arthritis because it blends well with clary sage, pine, juniper berry, cyprus, lavender, bergamot, sandalwood, and chamomile oil. The oil can be massaged into the skin or diluted in a bath to relieve coughs, colds, and scrofulous skin issues.
The main use for labdanum is to relax the nerves, ease stress, and promote a calm presence. When the thick labdanum oil is warm it truly is reputed to have the ability to change thoughts, which move emotions back through the brink of negativity, and into the light of connected control.
The oil will loosen tight muscles, and improve circulation; it carries more oxygen to the organs and the brain. When stress stretches the nervous system to the position of depression or when the emotions titter about the brink of a hormonal overload, labdanum will interact with all the adrenal glands and begin to balance hormone secretion.
Loyal labdanum users like to combine meditation with a few drops in the oil in order to reach a state of relaxation, often with other essential oils these kinds of as frankincense to deepen the breath or patchouli for its cherished grounding effects. That process helps neural impulses return to their normal state, and emotions flow in a stream of beneficial thoughts.
