For hair care

Black tea containing a significant amount of caffeine is effective in maintaining soft, shiny hair as well as helping in its proper growth.

As a diuretic

Because of its caffeine content, black tea serves as a mild diuretic, acting as a detoxifier and flushing out the toxins from the body, keeping you healthy.
