(Sweet Balm, Lemon Balm) Distilled from lemon balm, this is true Melissa and we have the GC analysis available. Most of the Melissa essential oil offered by other is a mixture of lemon-scented oils which might even include citronella; this is considered "the most adulterated essential oil in the industry". Not so with our true Melissa. It takes approximately 1.5 tons of the plant to obtain a pound of true Melissa essential oil, thus the expensive price of this true, unadulterated essential oil. This true Melissa is organically grown in England. The aroma of True Melissa is light, fresh and distinctly lemony. Its odor is uplifting and calming at the same time. This oil has proved useful in: oily skin, acne, cold sores, herpes, fungal infections, chronic coughs, colds (with headache), slowing rapid breathing, lowering blood pressure, colic, nausea, indigestion, menstrual pain & problems, regulating menstrual cycle, anxiety, depression, insomnia, migraine, tension, anger. May irritate sensitive skin and should only be used in small dilutions (4-6 drops per ounce of carrier oil) as well as avoided in pregnancy. Always use in the lowest recommended concentrations.
