Floral essential oil extraction method: distillation
Distillation is currently the most common and oldest method of essential oil extraction on the market, dating back to the 10th century in the Arab world. Depending on the technique, distillation can be divided into "water distillation" and "steam distillation." Water distillation, as the name suggests, involves completely immersing flower petals or herbs in water, heating it to boiling, and creating a high-pressure environment in the distillation vessel. The resulting steam is collected, and after a period of time, the oil and dew in the steam gradually separate due to their weight. The oil is then collected, and the essential oil extraction is largely complete. Steam distillation, on the other hand, involves placing the herbs and hot water separately and extracting the oil using steam.
