Does All Tea Have Caffeine?

So, does all tea contain caffeine? According to Whittard, the short answer is yes, all tea contains some amount of caffeine. This is because they all come from the same plant, known as the camellia sinensis. The only exception, however, are fruit and herbal infused teas. 

According to The Whistling Kettle, the majority of herbal teas are made with plants other than the camellia sinensis plant and will be completely free of caffeine. Herbal tea blends often include different dried fruits, flowers, and herbs. 

Per Healthline, some healthy herbal teas you can try at home include chamomile, peppermint, ginger, hibiscus, and echinacea tea — all of which are thought to offer different health benefits. Herbal teas like chamomile, for example, are supposed to help you relax or calm you down, while also promoting better sleep. Meanwhile, peppermint and ginger-based teas are thought to help if your stomach is bothering you.
