Our oil is small batch and we use the ancient process of steam distillation to extract the pure essential oil from our lavender. Each plant is harvested by hand and hand packed into the still to ensure none of the fragrant blossoms are wasted. It takes approximately 1 mature lavender plant to produce 1 fl oz of essential oil. We do not dilute our oil and it is therapeutic grade. This is why pure essential oils are more expensive than the more common diluted mass market oils.  We recommend using our oil in very small quantities for any application.
