Lemon balm, or Melissa Officinalis is one of the most important and sacred herbs in Alchemical tradition. 15 century alchemist Paracelsus believed that lemon balm had the power to completely revivify a man. Lemon balm was used throughout the middle ages to treat conditions like anxiety, stress, insomnia, and pain caused by indigestion. It has also been applied topically for wounds and cold sores.
Lemon balm is native to Europe but it is now grown all over the world.
