Just like other teas, black tea contains caffeine, amino acids, carbohydrates, proteins, potassium, minerals, manganese, fluoride, and polyphenols. In addition to these, it also contains catechins, tannins, guanine, purine, gallic esters, and xanthine. The antioxidants, polyphenols, are associated with a number of health benefits. Before the specific health issues are looked at from an individual perspective, let us get a brief understanding as to why tea has so many health benefits apart from being one’s favorite cuppa.
It is the mix of all the beneficial chemicals that this soothing and relaxing beverage contains that holds the key to all the health solutions.The biggest class of chemicals that are prevalent in tea are flavonoids that are found in many plants derived natural foods and are a natural class of antioxidants.

There are molecules called free radicals that are harmful to the body and antioxidants get rid of these free radicals which are a natural side effect of the harm done to the body by the effects of pollution and the natural process of aging. As free radicals are very unsteady, they generally react adversely with other vital molecules like DNA, which leads to grave failure and damage on a cellular level. If the effects that these free radicals leave behind are not erased, it could open the gateways for the developments of heart and other diseases.
