Lemon balm is an excellent nerve tonic for Vata and Pitta types. Lemon balm calms anxiety, promotes sound sleep, and heals cold sores when applied topically. I grow lemon balm in the shady, water-rich areas of my back yard. It is a very low-maintenance perennial, so even those who don't have much time for gardening can grow it easily.
