It can be said that it was the Arabs who revived the essential oil. Around the 10th century, Arabs studying alchemy invented steam distillation, and the Crusades between the 10th and 12th centuries led Europeans to learn how to distill and return to Europe with many precious plants, including herbs. Then, lavender was grown in England in the 13th century, and lavender water, which is aromatic distilled water, became available to the general public. In addition, Spain’s expedition by the Moors (Muslim Arab ethnic group) served as an opportunity to spread scent culture to each country, including France.
