==Special Precautions of Green Tea==
*To date, little is known about the side effects and safety concerns associated with use of green supplements. Since many green tea supplements contain caffeine, it's important to take caution if you're concerned about caffeine-related adverse effects (such as anxiety, increased heart rate and blood pressure, and the worsening of ulcer symptoms).
It's also important to note that free-radical scavengers (antioxidants) are unwelcome during chemotherapy treatment, as they -- in theory -- may diminish the activity of the drugs.
==The benefits of Green Tea are==
The green tea derivatives epicatechin, epigallocatechin, epicatechin-3-gallate, and epigallocatechin-3-gallate possess well-documented anticarcinogenic properties and anti-inflammatory and antioxidant capabilities. These properties are especially useful for patients with [[rosacea]] as inherent sun sensitivity is a hallmark of the disease. The photoprotective properties of green tea may lessen reactivity to ultraviolet light, thereby reducing the signs and symptoms of rosacea. Moreover, green tea extract has been shown to reduce the disruption of the skin barrier often seen in patients with the disease.
