Herb drinks, also known as herbal teas, are beverages made from infusing herbs, spices, and other plant material in hot water. Teas, a four-letter word, is one of the most popular types of herb drinks. Teas are made by steeping the leaves, flowers, or fruits of various plants in hot water. Commonly used herbs for teas include chamomile, peppermint, ginger, and hibiscus. Herbal teas are caffeine-free and can be enjoyed both hot and cold. They are often used for medicinal purposes, such as to aid digestion, reduce inflammation, and improve sleep.
