The short answer is yes, most teas do contain caffeine, but the amount varies depending on the type of tea, the leaves used, and the brewing process.

Caffeine in Herbal Teas: Exploring the Alternatives
When we talk about caffeine in herbal tea, it's important to understand that most herbal teas are naturally caffeine-free. This is because, unlike true teas, herbal teas (also known as tisanes) are not made from the leaves of the Camellia sinensis plant. Instead, they are infusions made from herbs, flowers, fruits, and roots. However, there are a few exceptions to this rule. Let's explore the caffeine content of some popular herbal teas.
Does Hibiscus Tea Have Caffeine?

Does Iced Tea Have Caffeine?
Generally, the answer to does iced tea have caffeine is yes. This is because most iced tea is simply brewed tea that has been cooled down and often served with ice.

The specific caffeine content will depend on the type of tea that was used to brew it.
