Lemon Balm herb

Also known as: Melissa officinalis, Lemon balm, Melissa

Overview

Lemon balm (Melissa officinalis) is a perennial herb native to Europe and Asia, characterized by its lemon-scented leaves. It has been traditionally used for its calming and digestive benefits. As an herbal supplement, lemon balm is primarily used to alleviate symptoms of anxiety, depression, and digestive issues. The herb is known for its soothing properties and is available in various forms, including teas, capsules, and extracts. Research on lemon balm is considered to be at a moderate level, with increasing evidence from clinical trials suggesting its efficacy in managing mood and stress-related conditions. The quality of available evidence is promising, but is limited by the small number of high-quality studies and heterogeneity between them. It is often used as a natural remedy to promote relaxation and improve sleep quality.

Benefits

Lemon balm has shown promise in reducing anxiety and depression. A meta-analysis indicated that lemon balm significantly reduced anxiety and depression scores compared to placebo (SMD -0.98 for anxiety and -0.47 for depression). It is also known to improve sleep quality, especially when anxiety or depression are contributing factors. Studies suggest it may improve blood lipids and alleviate digestive issues. Lemon balm appears to be particularly effective for acute anxiety in various populations, including hospitalized patients and those with premenstrual syndrome (PMS). While effect sizes for anxiety reduction are moderate to large, more research is needed to confirm its long-term efficacy, especially for chronic conditions.

How it works

The exact mechanisms of action for lemon balm are not fully understood, but it is believed to interact with neurotransmitter systems, particularly GABA, to exert calming effects. This interaction affects the nervous system, potentially influencing mood and sleep regulation. While specific molecular targets are not well-defined, lemon balm may modulate neurotransmitter activity, contributing to its anxiolytic and antidepressant effects. Limited data is available on its absorption and bioavailability, but oral ingestion is the most common method of consumption.

Side effects

Lemon balm is generally well-tolerated, with adverse events being similar to or less frequent than those reported with placebo. Common side effects are not well-documented, but mild adverse events may occur. Uncommon side effects (1-5%) may include dizziness, headache, nausea, abdominal pain, decreased appetite, and wheezing. No serious adverse events have been reported. Due to its effects on neurotransmitter systems, lemon balm may interact with sedatives or thyroid medications. While there are no established contraindications, caution is advised during pregnancy and breastfeeding due to limited data. Use with caution in children and elderly populations due to limited research in these groups.

Dosage

While the minimum effective dose of lemon balm is not well-established, studies have used doses of 1 g per day. Typical dosage ranges are between 1-2 g per day, though more research is needed to confirm optimal efficacy. The maximum safe dose has not been established, but doses up to 2 g per day are commonly used without significant adverse effects. For sleep benefits, it is best taken before bedtime, or as needed for anxiety. Oral ingestion is the most common form, but topical use may also be beneficial for skin issues. There is limited data on absorption factors and no established required cofactors.
