When it comes to tea blends, there are two main categories: herbal and caffeinated. Herbal teas are made from a variety of plants and herbs, while caffeinated teas typically come from the Camellia sinensis plant. When blending for flavor, the focus is on creating unique taste combinations using different teas, herbs, flowers, and fruits. However, when blending for health benefits, specific ingredients may be chosen based on their purported medicinal properties. For example, ginger can be added to help with digestion or chamomile for its calming effects. It's important to note that while some ingredients may have health benefits, they should not be used as a replacement for medical treatment. Overall, customizing tea blends can allow you to create unique flavors and potentially enhance certain health benefits.
