Nettle Tea is a Green Leaf Herbal caffeine-free tea that brews a delicious vivid greenish-yellow cup of tea with a distinct aroma. Additionally, the nettle leaves contain many healthful antioxidants, vitamins and minerals and is used as a detox drink. Nettle leaf tea has long had a healthy reputation. It’s been an important part of traditional medicine in several cultures around the world. Nettle leaf tea is derived from the leaves of the common nettle plant, also known as the stinging nettle. The scientific name for this plant is Urtica dioica. The ‘stinging’ moniker is apt, as handling the plant with exposed skin is known to produce a burning sensation that persists after contact.
