“Essential oils” are concentrated plant extracts that capture the natural aroma, flavor, and beneficial properties of the plants from which they are derived. These oils are obtained through various extraction methods, such as distillation or cold pressing, and are used in a wide range of applications, including aromatherapy, skincare, and natural remedies.
1. What Are Essential Oils?
Source: Essential oils are extracted from various parts of plants, including leaves, flowers, bark, stems, roots, and seeds. The oils contain the essence of the plant’s fragrance and the concentrated chemical compounds responsible for its therapeutic properties.
Extraction Methods:
– Steam Distillation: The most common method where steam is passed through plant material, capturing the essential oil as it vaporizes. The vapor is then condensed back into liquid form.
– Cold Pressing: Typically used for citrus oils, where the oil is mechanically pressed from the fruit’s rind without using heat.
– Solvent Extraction: Used for delicate flowers like jasmine, where a solvent is used to extract the essential oil, later removed to leave behind the pure oil.
