Steam Distillation Explained
During steam distillation, the lavender flowers (and sometimes leaves and stems) are placed in a distillation apparatus. Steam is then passed through the plant material, causing the essential oil to vaporize and rise into a condenser, where it is cooled and converted back into a liquid. This liquid is a mixture of water and essential oil, which are then separated based on their different densities. The essential oil, being less dense, floats on top of the water and is collected as the final product.
Quality Control and Variations
The quality of the lavender oil can vary significantly based on factors such as the quality of the plant material, the distillation process, and the geographical location of the plants. High-quality lavender oil should have a clear, pale yellow color and a sweet, floral aroma. Variations in oil quality can lead to differences in its therapeutic effectiveness and shelf life.
