Our most expensive and rare oil, Melissa essential oil has a sweet, fresh, citrus-like fragrance and is steam distilled from the fresh flowering tops, leaves and stems of the Melissa officinalis plant. With a wide range of beneficial properties, Melissa can be used for calming the nerves, a positive affect on mood, and seasonal threats. Because the Melissa plant has an oil yield of less than 1/10 of 1%, it is one of the most commonly adulterated oils. For aromatic, topical, or dietary use.
