Black tea has been studied in Great Britain (of course), and found to be a proven stress reducer. Actually, it doesn't relax you so much as it prevents those nasty stress hormones (like cortisol) from skyrocketing and it is also able to fight against the formation of blood clots.
Chamomile Tea is a Powerhouse
Herbalists for centuries have been reporting that chamomile tea reduces stress. Personally, I love the taste of chamomile tea. So I was very excited to learn that it's somewhat amazing in all its benefits. For example, WebMD reports on studies that show chamomile tea to have the additional benefits of blocking complications from Type 2 diabetes including loss of vision as well as nerve and kidney damage.
Additionally, one research study published in the Journal of Agricultural and Food Chemistry found that chamomile tea heals inflammation along with assorted skin diseases, open wounds/ulcers and even gout. WebMD also reports that recent studies have found that simple little old chamomile tea can stunt growing human cancer cells.
Green tea and ginseng tea also not only provide great health benefits, but also to fight stress well.
Nice to know a no-calorie, inexpensive, easy-to-find beverage can do so much for you, right? Add that to a real, traditional English tea time and you've really got yourself a stress-break.
