The term "true tea" covers only black, green, white and oolong teas made from the leaves of the Camellia sinensis plant; "herbal teas" (infusions) like chamomile, linden or sage are prepared from the leaves, flowers or roots of entirely different plants that are botanically unrelated to the tea plant. That distinction may look like a small naming difference, but it has real consequences for caffeine content and brewing method.
Why is the caffeine gap so large?
Camellia sinensis naturally contains caffeine; black tea usually carries the most, while green and white tea carry somewhat less due to how they're processed. Herbal teas are almost entirely caffeine-free by nature, since the source plant contains none at all — which is why herbal tea is the go-to choice for a warm evening drink that won't interfere with sleep.
Why does the brewing method differ?
True tea leaves release tannins if steeped too long, leaving a bitter, astringent taste; that's why the recommended steeping time for each type — roughly 2-3 minutes for green tea, 3-5 for black — shouldn't be exceeded. Herbal teas carry far less risk of that bitterness, and many are deliberately steeped longer, 5 to 10 minutes, to draw out a stronger flavour.
Some products with "tea" in their name can be confusing; kombucha, for instance, is actually made by fermenting true tea brewed from Camellia sinensis, so technically it's a derivative of true tea rather than an herbal tea. Fruit teas, meanwhile, are usually a blend of dried fruit pieces and plants like hibiscus, and may not contain any true tea leaf at all.
Colour isn't always a reliable clue either: hibiscus- or cranberry-based herbal teas can turn a deep red, but that comes from the plant's own pigment rather than the oxidation process that colours true tea. So a drink being called "tea" doesn't necessarily mean it contains Camellia sinensis — the ingredient list on the back of the pack is the most reliable source on that question.
White tea is an interesting case within this split: it's still made from Camellia sinensis, but from buds and young leaves with minimal processing, so it counts as a true tea while also being the least processed type. Oolong sits between black and green tea, only partially oxidized, and comes from the same plant too.
Cup size and water temperature are also handled differently between the two groups: true teas are usually brewed with water below boiling, roughly 70-95°C, while most herbal teas can take fully boiling water since the risk of releasing tannins is much lower. That difference makes it easy to use the same pot or cup for either type, adjusting only the steeping time and water temperature.

Yeşil çayı önerilen 2-3 dakikayı aşarak 6-7 dakika demledim, gerçekten tanenler açığa çıkıp buruk bir tat bıraktı; bir dahaki sefere süreyi mutlaka takip edeceğim.
Akşamları siyah çay yerine adaçayı denemeye başladım, metinde de dendiği gibi kafeinsiz olması uykuyu etkilemiyor, tek fark 5 dakikadan fazla demlemem gerekmesi.
Kombu çayının aslında gerçek çaydan yapıldığını hiç bilmiyordum, bunu öğrenince markette alırken içindekiler listesine bakma alışkanlığı edindim.
