Relax and stay hydrated with some herbal iced tea.
All teas come from the Camellia sinensis tea plant - whether black, green, white, or oolong tea. The difference is in the way the leaves are processed. The Camellia plants are rich in polyphenols and antioxidants. Research suggests regular tea drinkers (2 or more cups a day) have a lower risk of heart disease, stroke, and lower LDL cholesterol.
Iced tea is a form of cold tea, usually served in a glass with ice. It may or may not be sweetened. Iced tea is also a popular packaged drink. It can be mixed with flavored syrup, with common flavors including lemon, peach, raspberry, lime, passion fruit,strawberry, and cherry. While most iced teas get their flavor from tea leaves (Camellia sinensis), herbal teas are also sometimes served cold and referred to as iced tea. Iced tea is sometimes made by a particularly long steeping of tea leaves at lower temperature (one hour in the sun versus 5 minutes at 180-210 °F / 80-100 °C). Some people call this "sun tea". In addition, sometimes it is also left to stand overnight in the refrigerator. From Wikipedia
