A Definitive Look at Lemon Myrtle and Caffeine
Many people turn to herbal teas as a low-caffeine or no-caffeine alternative to coffee or traditional black and green teas. When considering a vibrant, citrus-flavoured option like lemon myrtle, the question of its caffeine content is a common one. The clear and simple answer is that lemon myrtle (Backhousia citriodora) does not contain any caffeine. This native Australian plant offers a naturally uplifting and refreshing brew without the stimulating effects associated with caffeine.
This absence of caffeine is due to the fundamental difference between the lemon myrtle plant and the tea plant (Camellia sinensis). While black, green, and oolong teas all contain varying levels of caffeine, herbal infusions like lemon myrtle are made from other plant parts, such as leaves, flowers, or roots, that do not naturally produce the stimulant.
The Health Benefits of a Caffeine-Free Herb
For those sensitive to caffeine or looking to reduce their intake, lemon myrtle presents an excellent option. Its benefits are not derived from a jolt of energy but rather from its unique chemical composition, particularly its high concentration of citral.
Key Benefits of Lemon Myrtle
- Rich in Antioxidants: The high level of citral in lemon myrtle acts as a potent antioxidant, helping to protect the body's cells from damage caused by free radicals.
- Promotes Relaxation and Sleep: Its soothing aroma and mild sedative properties can help calm the nervous system, making it an ideal beverage for unwinding in the evening.
- Supports Immune Health: Lemon myrtle's antimicrobial and anti-inflammatory properties can aid in fighting infections and alleviating symptoms of colds and flu.
- Aids Digestion: It is known to help settle bloating and gas, and its anti-inflammatory agents can regulate the digestive system.
- Supports Skin Health: The antiseptic and anti-fungal qualities of citral make it beneficial for topical applications to treat various skin conditions.

How to Enjoy Lemon Myrtle
Preparing and enjoying lemon myrtle is a straightforward process, whether you prefer it hot or cold. For a traditional hot brew, simply steep dried lemon myrtle leaves or flakes in boiling water for 3-5 minutes. The flavour is naturally vibrant and requires no additives, but some may enjoy a touch of honey or a slice of lemon for an extra citrus boost. It can also be added to black or green tea for a lemony twist without a significant caffeine increase.
For a refreshing iced tea, follow the same steeping process, allow it to cool, and then serve over ice. It can also be combined with other herbal ingredients for a customised infusion. For example, blending with peppermint or ginger can create a delicious and soothing digestive tea.
A Safe and Natural Choice
Beyond its culinary uses, lemon myrtle's natural properties make it a safe and versatile ingredient in many products. Its high citral content gives it a naturally antibacterial and anti-fungal quality, leading to its use in personal care items like soaps, lotions, and shampoos. It has also been explored in cleaning products, offering a pleasant and effective natural alternative to harsh chemicals. This versatility, combined with its caffeine-free nature, underscores its appeal as a wholesome, natural option for various applications.
While largely considered safe for general consumption, those with specific health concerns, especially pregnant women, should consult a healthcare provider before use. As with any herbal product, moderation is key. The plant's essential oil should be used with more caution than the brewed leaves, especially when applied topically or used by sensitive individuals.
