What To Know
- The steam and essential oil vapors are then condensed and separated, resulting in the pure essential oil.
- Place the lemon balm plant material in a container and add the solvent.
- Once extracted, lemon balm oil should be stored in a cool, dark place in an airtight glass jar or bottle.
Lemon balm (Melissa officinalis), a member of the mint family, is renowned for its refreshing citrusy aroma and therapeutic properties. Its essential oil, extracted from the plant’s leaves and flowers, is highly valued for its calming and invigorating effects. In this comprehensive guide, we delve into the art of extracting lemon balm oil, empowering you to harness the plant’s aromatic essence.
Methods of Extraction
There are several methods available for extracting lemon balm oil, each with its unique advantages and disadvantages.
#1. Steam Distillation
Steam distillation is the most commonly used method for extracting essential oils from plants. It involves passing steam through the plant material, which causes the volatile compounds to evaporate. The steam and essential oil vapors are then condensed and separated, resulting in the pure essential oil.
#2. Hydrodistillation
Similar to steam distillation, hydrodistillation uses water instead of steam. The plant material is submerged in water and heated, releasing the essential oils. The water and oil vapors are then condensed and separated.
#3. Cold Pressing
Cold pressing is a mechanical method that involves crushing the plant material to release its oils. This method is often used for extracting citrus oils, but it can also be used for lemon balm.
#4. Solvent Extraction
Solvent extraction uses organic solvents, such as ethanol or hexane, to dissolve the essential oils from the plant material. The solvent is then evaporated, leaving behind the concentrated essential oil.
Essential Equipment
Regardless of the extraction method you choose, you will need the following essential equipment:
- Plant material (fresh or dried lemon balm leaves and flowers)
- Distillation apparatus (for steam or hydrodistillation)
- Cold press (for cold pressing)
- Solvent (for solvent extraction)
- Funnel and filter paper
- Glass jars or bottles for storage
Step-by-Step Extraction Process
Steam Distillation:
1. Place the lemon balm plant material in the distillation apparatus.
2. Fill the apparatus with water and heat it until steam is produced.
3. Collect the steam and essential oil vapors in a condenser.
4. Allow the vapors to cool and condense, separating the oil from the water.
Hydrodistillation:
1. Place the lemon balm plant material in a distillation apparatus.
2. Fill the apparatus with water and heat it until it boils.
3. Collect the water and essential oil vapors in a condenser.
4. Allow the vapors to cool and condense, separating the oil from the water.
Cold Pressing:
1. Crush the lemon balm plant material using a cold press.
2. Collect the released oil and filter it through a funnel and filter paper.
Solvent Extraction:
1. Place the lemon balm plant material in a container and add the solvent.
2. Stir the mixture and allow it to sit for a period of time.
3. Filter the mixture and evaporate the solvent, leaving behind the concentrated essential oil.
Storage and Shelf Life
Once extracted, lemon balm oil should be stored in a cool, dark place in an airtight glass jar or bottle. The oil can last for up to two years if stored properly.
Uses of Lemon Balm Oil
Lemon balm oil has a wide range of uses, including:
- Aromatherapy (calming, uplifting, and refreshing)
- Massage (relaxing and soothing)
- Skin care (antibacterial, anti-inflammatory, and antioxidant properties)
- Culinary (flavoring teas, desserts, and beverages)

Frequently Asked Questions
1. What is the yield of lemon balm oil per pound of plant material?
The yield varies depending on the extraction method, plant quality, and other factors. Typically, steam distillation yields around 0.5-1% essential oil.
2. Can I use dried lemon balm leaves for extraction?
Yes, dried lemon balm leaves can be used, but they may yield less oil than fresh leaves.
3. How can I tell if my lemon balm oil is pure?
Look for a clear, pale yellow to amber-colored oil. Avoid oils that are cloudy or have a strong, pungent odor.
