Lavender essential oil has a mild flavor and not aggressive "olfactory"! I use it in my diffuser few drops mixed with water and it plunges the room into a soothing and relaxing atmosphere. I am a person who has a hard time falling asleep and that tends to insomnia, the lavender oil calms me and relaxes me for a serene sleep. The perfume remains in the air this will keep a good light smell the day before returning the diffuser 1 hour in the evening before bedtime. I also enjoyed the bottle size, 30ml, great !!!! I highly recommend this product!
