What is a common characteristic of herbal teas?

A common characteristic of herbal teas is that they are derived from herbs, which distinguishes them from traditional teas that are made from the leaves of the Camellia sinensis plant. Herbal teas can include a wide range of botanicals, such as flowers, leaves, seeds, and roots, and are not categorized as true teas. This versatility allows for a variety of flavors and potential health benefits, making herbal teas a popular choice among consumers for both enjoyment and wellness.

The other characteristics listed do not accurately describe herbal teas. For instance, herbal teas generally do not contain caffeine since they are not made from traditional tea leaves. Additionally, they can be enjoyed both hot and cold, and there is no requirement for them to be sweetened, as personal taste plays a significant role in how they are consumed.
