April 4, 2023
What is herbal tea?
Herbal teas, sometimes known as herbal infusions or tisanes, are beverages made by steeping dried herbs, flowers, fruits, and/or spices in hot water for consumption.
People often add accompaniments like milk, plant-based milk, sweeteners, and other ingredients.
How is herbal tea different from other teas?
We make traditional teas like green or black tea from tea plant leaves called Camellia sinensis. Herbal teas do not contain traditional tea plant leaves.
Are herbal teas caffeinated?
Most herbal teas are naturally caffeine-free. However, some herbs like yerba mate and guayusa contain caffeine, and manufacturers may add these caffeine-containing herbs to herbal tea blends.
If you want to avoid caffeine, check the labels for ingredients to ensure caffeine-containing herbs are not included.
Do herbal teas have bioactive properties?
Herbal teas may contain bioactive compounds that potentially provide health benefits, such as anti-inflammatory and antioxidant properties.
However, the strength and effectiveness of these compounds may vary depending on the purity, potency, dose, preparation method, and more.
It's important to note that herbal teas are not a substitute for medical treatment or advice and should not be relied upon to cure or treat any medical conditions.
