Lemon balm is an heirloom herb that grows much like mint, except far less invasive. It has a citrusy smell with a touch of mint and is amazing in teas. Used to help soothe symptoms of anxiety, depression, and the common cold, this herb is loaded with antioxidants and vitamins as well as essential oils that should find their place in anyone’s tea garden. Home-grown tea is far better than anything from the store since it is picked at peak freshness.
