100% pure lemon balm hydrosol is produced during the steam distillation of our essential lemon balm oil at 29 Rows. None of the benefits of lemon balm are lost during this process which is one of the many reasons lemon balm is loved for it's versatility. It is a softly floral, lemon-like, herbaceous aroma. The benefits of lemon balm hydrosol include emotional distress relief, rashes, burns, poison oak and anti-asthmatic support. Enjoy!
