What Is Lemon Balm?

Lemon balm is a lemon-scented herb from the mint family used medicinally since antiquity for anxiety and insomnia. Rosmarinic acid and flavonoids are its primary actives. Unlike valerian, lemon balm also shows mild cognitive benefits through weak acetylcholinesterase inhibition — unusual for an anxiolytic herb.

How It Works: The Science

Rosmarinic acid inhibits GABA transaminase (increasing GABA availability) and free radical scavenging via Nrf2 activation. Lemon balm flavonoids mildly inhibit acetylcholinesterase (improving acetylcholine signalling) and bind to muscarinic and nicotinic receptors. This dual anxiolytic-cognitive action profile is unique.
