Osmanthus Absolute Usage And Synthesis

Application

1. Skin Care: Osmanthus essential oil contains ionones, making it suitable for oily-on-the-outside, dry-on-the-inside skin with large pores. It has excellent repairing and nourishing effects on dry and aging skin, leaving it smooth and delicate. The ionone content in osmanthus flowers is higher than in violet leaves, thus its ability to promote cell regeneration is exceptional, making it a rare and valuable skincare oil. Osmanthus essential oil can also promote blood circulation, improve cell tissue, and invigorate skin vitality, accelerating blood circulation and improving pale complexion. 2. Body Care: Osmanthus essential oil can soothe bronchial activity, helping to relieve coughs, reduce phlegm, and alleviate asthma. It can stimulate circulation, effectively addressing problems such as poor blood circulation caused by weather, lifeclass habits, and environmental factors. Osmanthus essential oil also has excellent reproductive and childbirth-aiding properties; women can use it for lower abdominal massage to regulate hormones and promote regular menstrual cycles. 3. Mental Well-being: Osmanthus essential oil is an excellent mood booster, offering relief from fatigue, headaches, and menstrual cramps. It is also a good mood enhancer during sexual activity.
