White tea comes from the tea plant and is the least processed type of tea, making it the most delicate in flavor. It is full of antioxidants, which may provide various health benefits. Research shows that white tea helps with anti-inflammation, reducing heart disease risk, lowering insulin resistance, reducing cancer risk, improving dental health, lowering the risk of osteoporosis, improving brain health, and slowing skin aging. While generally considered safe, white tea contains caffeine, which can lead to insomnia and anxiety. Some brands of white tea bags may contain lead, so pregnant and breastfeeding women should avoid it.
