The history of herbs and spices is far more ancient than that of tea. Herbal Infusions are not tea, per se, as they do not come from the Camellia Sinensis plant.
Herbal Infusions include many well-known herbs such as mint, flowers such as hibiscus and chamomile, roots like licorice and ginger, and other botanicals including rooibos and lemongrass. Some blends combine many herbs and even add seeds, berries, nuts and even cocoa.
Herbal infusions have a wide variety of claimed health benefits and cures, from indigestion to allergies to insomnia. There are infinite combinations and possibilities for creating herbal infusions, and all of them are free of caffeine.
