==Special Precautions of Black Tea==

* Black tea is safe for most adults. Too much black tea, such as more than five cups per day, can cause side effects because of the caffeine. These side effects can range from mild to serious and include headache, nervousness, sleep problems, vomiting, diarrhea, irritability, irregular heartbeat, tremor, heartburn, dizziness, ringing in the ears, convulsions, and confusion.

*People who drink black tea or other caffeinated beverages all the time, especially in large amounts, can develop psychological dependence.

* Oral Health : Research suggests that catechin antioxidants in black tea may reduce oral cancers. Tea's polyphenols and tannin perform as antibiotics, preventing bacteria that cause tooth decay, and the polyphenols in tea can help to keep in check the bacteria that cause bad breath.

* Immune System : Tea is full of substances called "tannins," which studies have shown have the ability to fight viruses such as influenza, dysentery and hepatitis. One such tannin named "catechin" helps suppress tumors. Black tea also contains alkylamine antigens, which help boost immune response.
