What is an essential oil?

The word Essential itself means Essence. Essential oil is an extract obtained from plants, it can be said that there is an extract obtained from plants that can be in the form of aroma or taste. The essential oil can also be called extract oil or essential oil. Which are obtained by different extraction methods. Different parts of the plants can be used depending on the essential oil obtained. The flowers of the plant are generally used to obtain the most aromatic and aromatic oils. In addition to flowers, various other plant parts such as leaves, bark, roots, and fruit peels are utilized for extracting essential oils. This article aims to provide valuable insights on the appropriate selection and buy essential oils in India, enabling readers to make informed decisions.

Essential oils are considered beneficial because they are usually up to 75 percent more potent and effective than herbs. In a way, it is the essence of the properties of flowers and plants, so essential oil is a completely natural product, so it is believed that it is very effective. Careful usage is essential when applying lemon oil, as it possesses significant potency and may result in side effects if mishandled.

How is an essential oil made?

About 250 kg of lavender flowers makes 1 kg of lavender oil.

About 1000 kg of rose petals makes 1 kg of rose oil.

Method of preparation of essential oil

by distillation

The process of distillation is commonly employed to produce popular essential oils like lavender, peppermint, tea tree oil, patchouli, and eucalyptus. Raw plant material, which includes flowers, leaves, wood, bark, roots, seeds, or peels, is put into an alembic (distillation apparatus) over water. As the water is heated, it vaporizes. is formed that passes through the plant material, vaporizing the plant matter and also into volatile compounds. The vapors flow through a duct, condensing back into liquid, which is then collected in a receiving vessel. goes.

Most oils are distilled in a single process. Ylang-ylang (Cananga odorata) stands out as an exception to the typical extraction methods used for essential oils, as it is purified through a process called fractional distillation.

Similarly, the resulting condensed water from this distillation process is commonly known as hydrosol, hydrolat, herbal distillate, or plant water essence. These hydrosols have gained popularity as scented products and are widely available for purchase. Hydrosols encompass a variety of examples, such as rose water, lavender water, lemon balm, clary sage, and orange blossom water. These are produced through the process of distillation, where the aromatic compounds from plant materials are extracted along with water vapor, resulting in a fragrant and therapeutic water-based solution. The utilization of herbal distillates in cosmetics is becoming increasingly prevalent in recent times.

Squeezing by Expression

Most citrus fruit rind oils are obtained by machines or cold-pressed. Citrus fruit oils are often more affordable compared to other essential oils due to their abundant oil content in citrus peels and the cost-effective nature of growing and harvesting the raw material.

Lemon or sweet orange oil is obtained as a byproduct of the citrus industry. Before the invention of distillation, all essential oils were extracted by mechanical means.

by solvent extraction

Many flowers do not possess sufficient amounts of volatile oil to undergo complete extraction through steam distillation due to the delicate nature of their chemical components, which can be easily damaged by the high temperatures involved. As an alternative, hexane is utilized as a solvent for oil extraction. Another method involves the use of solvents like supercritical carbon dioxide. Concretions, on the other hand, pertain to extracts acquired through the employment of hydrophobic solvents such as hexane. These extracts consist of a blend of essential oils, waxes, resins, and other plant materials that are soluble in oil (lipophilic).

Solvent extraction

Although highly aromatic, concrete contains large amounts of non-aromatic waxes and resins. Another solvent, such as ethyl alcohol, is often used to extract aromatic oils from the concrete. The alcohol solution is gradually cooled to a temperature of -18 °C (0 °F) within 48 hours. This cooling process facilitates the precipitation of waxes and lipids, causing them to separate from the solution. The precipitate is then filtered and the ethanol is evaporated from the remaining solution, using a vacuum. is removed by a purge or both, leaving the absolute behind.

 When steam distillation is used this method can avoid petrochemical residues in the product and the loss of some of the “top notes”. It does not give you the result in one go. Supercritical carbon dioxide is employed to extract both the wax and essential oils present in the concrete. By lowering the extraction temperature within the same extractor, subsequent processing with liquid carbon dioxide enables the separation of the wax from the essential oils. 

This particular technique, carried out at low temperatures, safeguards against the breakdown and alteration of the compounds. Upon completion of the extraction, the pressure is reduced to ambient levels, causing the carbon dioxide to revert to its gaseous state without leaving any residue behind.

Benefits of essential oil

Here are some common uses of essential oils and aromatherapy to treat health problems. What is included in general for each essential oil?
