our ylang ylang ( e-lang-e-lang) is the “extra” grade which is the quality most suitable for aromatherapy. the extra grade is the first part of the distillation where the lighter, more floral notes are distilled off first. apart from a better aroma this vibrant part will have better results in aromatherapy. there are other grades available that are all pure but of a lower quality. we only ever use this “extra” quality to gurantee better results for our customers. 我们的依兰精油是最适合于芳香疗法的特级依兰精油，来自于蒸馏法的第一道萃取工序，因而更轻盈更芳香。
