When people visit an herbal garden, they are usually fascinated by the fragrance of the herbal plants like peppermint, rosemary or lavender. The fragrance of these herbs are the essence of their existence. That’s why the oil extracted from these herbs are called “essential” oils. Because the word “essential” refers to the essence of the oil that has been driven from the characteristic aroma (essence) of the herbal plant.
Here is an introduction to the most fascinating essential oils that have some of the most wonderful medicinal properties:
So what are essential oils?
Essential oils are highly concentrated substances driven from a plant’s aroma or flavor. However some plants are generous with their scented oil like rosemary, tarragon or mint. If you rub a few leaves of rosemary or tarragon on your hands you can smell their scent. However, 3 million flowers of Jasmine (1000 Ib) make up only for one Ib of jasmine essential oil.
Essential oils don’t always come from the open flowers; they could also come from different parts of the plant such as flower buds, leaves or stem.
There are three different methods in producing the essential oils such as steam distillation, extraction and expression.
In steam distillation method, the plant is steamed and the essential oil evaporate. Then the hot vapor is cooled into the mixture of both water and oil. Since essential oils aren’t soluble it’s easy to separate the two and extract the essential oil.
In this method the oil is cold-pressed from the plant at room temperature by using machinery or hands. The oils that are extracted by expression method are super sensitive to heat and are easily damaged by steam distillation heat. The Cold-press expression is mostly used for extracting oil from citrus fruits such as limes, lemons, oranges or grapefruit that are sensitive to heat.
In this method a chemical or organic solvent is added to the plant and the essential oils are extracted based on different solubility. The essential oils are soluble in organic or chemical solvent and the essential oil remains after the solvent is evaporated. However in this method some chemicals may have remained in the solvent.
