Lemon balm — Köhler 1887 botanical illustration

A lemon-scented mint relative valued in Persian and European medicine for nearly a thousand years. Calming, with a small but solid modern evidence base for sleep, mood, and cold-sore healing.

  • Mild calming and anti-anxiety action
  • Supports sleep, particularly when paired with valerian
  • Eases nervous stomach
  • Topical cream supports cold-sore healing
  • Boosts the activity of GABA — the body's main calming neurotransmitter
  • Some evidence for short-term cognitive support — calmer focus, not stimulation

Active in Rosmarinic acid, Citral, Citronellal, Linalool, Tannins.
