The Powerful Health Benefits of Lemon Myrtle
Lemon myrtle ($Backhousia citriodora$) is far more than just a fragrant leaf; its rich chemical composition offers a wide array of health-promoting properties. The star compound, citral, which is present in higher concentrations than in lemongrass or lemon zest, is responsible for many of its therapeutic effects.
Antimicrobial and Anti-inflammatory Properties
Research has shown that lemon myrtle possesses powerful antimicrobial and anti-inflammatory capabilities.
- Combats infection: The essential oil is effective against a broad spectrum of microorganisms, including bacteria, fungi, and viruses. This makes it a formidable natural remedy for fighting colds, flu, and respiratory infections when inhaled as a vapor.
- Soothes skin conditions: Its antiseptic and anti-inflammatory qualities help to calm and soothe irritated skin, making it beneficial for conditions like acne, eczema, and psoriasis when applied topically (diluted).
- Supports oral health: Used in oral health products, lemon myrtle can cleanse the mouth and combat bacteria associated with tooth decay and bad breath.
Antioxidant Effects and Cellular Protection
The antioxidant capacity of lemon myrtle helps protect the body from oxidative stress caused by free radicals.
- Fights aging: By neutralizing free radicals, the antioxidants can slow down premature aging and contribute to more youthful, radiant skin.
- Boosts immunity: A strong immune system is supported by the herb's rich content of antioxidants and essential vitamins and minerals, including vitamin C, vitamin E, calcium, zinc, and magnesium.
- Supports overall wellness: Regularly consuming antioxidant-rich lemon myrtle can contribute to overall vitality and protect cells throughout the body.
Mental Wellbeing and Digestive Health
Beyond its physical benefits, lemon myrtle's calming properties and digestive aid are highly valued.
- Reduces stress and anxiety: The refreshing and uplifting aroma is well-known in aromatherapy for its ability to reduce stress, improve mood, and promote relaxation. It can create a calming atmosphere and aid in achieving better sleep.
- Aids digestion: Lemon myrtle tea is a traditional remedy for digestive issues. Its carminative properties help soothe an upset stomach, reduce bloating, and calm intestinal inflammation.
Culinary Applications and Tips
Lemon myrtle is a versatile and flavorful ingredient in the kitchen, offering a clean, zesty flavor that is more potent than lemon zest.
- Cooking: Add dried, ground leaves sparingly to marinades for fish, chicken, and other meats. It works well in sauces, dressings, and dips. A popular technique is to use it similarly to how one might use a bay leaf, adding it to dishes for a flavour infusion.
- Baking and desserts: The herb can impart a vibrant citrus note to cakes, biscuits, cheesecake, and sorbets without adding acidity, which is particularly useful in dairy-based recipes.
- Beverages: Brewing the dried leaves into a naturally caffeine-free herbal tea is one of the most popular ways to consume it. It can be served hot or cold and offers a soothing, invigorating flavor.
Skincare and Household Applications
Thanks to its antimicrobial prowess and pleasant aroma, lemon myrtle has a wide range of non-culinary uses.
- Skincare: Infused into soaps, lotions, and facial cleansers, its properties help cleanse and clarify the skin. Its astringent qualities can tighten pores and balance oil production, making it a valuable ingredient for oily and acne-prone skin.
- Aromatherapy: The essential oil can be diffused to purify the air, repel insects, and create a relaxing or energizing atmosphere, depending on its pairing with other oils.
- Natural cleaner: The potent antibacterial and antifungal properties make it an excellent natural disinfectant for cleaning surfaces in the home. A simple spray can be made with water, white vinegar, and drops of lemon myrtle essential oil.
