The essential oil has been used for thousands of years. It is naturally occurring essences found in various parts of plants. It is important to understand that not all are created equal. Most ‘essential oils’ are of perfume grade, made with synthetic fragrance and chemicals. However, pure and therapeutic grade essential oils are the highly concentrated, aromatic essences of trees, shrubs, herbs, grasses, resins and flowers. They can be clear, amber, yellow, green, and even dark blue in colour and range from very runny to almost solid in consistency.
Refer excerpt below from Aromahead Institute:
“The scent you smell when breathing in the delicious aroma of a rose is the essence, or essential oil, of Rose. Some plants give off an aroma; others do not. The reason why only some plants have an essential oil remains one of Mother Nature’s mysteries.
Essential oils are highly aromatic substances found in specialized cells or glands of certain plants. Technically, when this substance is still in the plant, it is called an essence. These essential oils are used by the plant for protection from predators and to attract pollinators. After the distillation of a plant, the aromatic substance is referred to as an essential oil.
The essential oils in our bottles are substances that have been extracted from the plant. These oils are highly concentrated. It takes approximately 50 rose flowers to create just a single drop of Rose oil! Because they are so concentrated, essential oils are precious. Even used sparingly, they can offer immense therapeutic benefit.”
