Frequently asked questions

What is lemon balm good for?

Lemon balm (Melissa officinalis) is a fragrant, lemon-scented herb from the mint family, traditionally used to calm the nerves, lift the mood and support restful sleep. It’s also used to ease digestive discomfort, particularly when stress affects the stomach, and applied to the skin for cold sores. Its botanical name Melissa comes from the Greek word for honeybee, as bees love its flowers.

Does lemon balm help with stress and anxiety?

Yes, lemon balm is one of the most popular herbs for stress, nervous tension and mild anxiety. It’s thought to work by supporting the activity of GABA, a calming messenger in the brain, and some clinical studies suggest it may help improve calmness, mood and focus. Unlike stronger sedative herbs, lemon balm is gentle enough to take during the day. It’s often combined with chamomile, passionflower or skullcap.

Can lemon balm help you sleep?

Lemon balm is traditionally used to support restful sleep, especially when a busy mind or nervous tension makes it hard to switch off. Research suggests it may work particularly well when combined with valerian. A warm cup of lemon balm tea in the evening is a classic way to wind down before bed, and it’s gentle enough to be a family favourite.

Is lemon balm good for cold sores?

Lemon balm is a traditional topical remedy for cold sores. Studies have found that creams containing concentrated lemon balm extract may help speed healing and ease redness and swelling when applied at the first sign of tingling. Its natural antiviral compounds, including rosmarinic acid, are thought to be responsible for this effect.

Are there any side effects of lemon balm?

Lemon balm is generally very safe and well tolerated when taken as directed, though some people may experience mild stomach upset or drowsiness. Avoid driving or operating machinery if affected, and don’t combine it with alcohol. Check with your healthcare professional before use if you have a thyroid condition or take thyroid medication, sedatives or other prescription medicines, or are pregnant or breastfeeding, and check the label’s age guidance before giving it to children.
