By distillation, about 3500 to 5000 kg of rose can be extracted from 1 kg of rose essential oil, that is to say, about 30 flowers can extract a small drop of rose essential oil. This is one of the reasons why the price of rose essential oil has always been among the best. 

2. Have been imitated all the time and have never been surpassed! Rose essential oil components are very complex, more than 400 components have not yet been identified, so artificial can not be synthesized, at most can only synthesize some essence similar to rose, so its smell can not be completely imitated. She has a unique aromatic charm, which is another reason why rose essential oils are expensive.
