What You Should Pay Attention About Drinking Black Tea?

Drinking black tea in moderate amounts is safe for most people in  general. Drinking large amounts of black tea or more than six or seven big cups strong tea  a day, may cause health problems. That's mostly because of caffeine-related side effects.

Side effects of black tea may include:

Anxiety and difficulty sleeping

Faster breathing

Irregular heartbeat

Nausea and vomiting

Headache

Increased urination

Tremors

Nervousness and restlessness

Ringing in the ears

Black tea or black tea supplements may interfere with other medicines and supplements you are taking. Some medicines can cause caffeine to stay in your body longer than usual. Talk to your doctor to see if medicines you are taking may have this effect.

Always tell your doctor about any supplements you are taking, including natural ones and those bought without a prescription. That way, your doctor can check on any potential side effects or interactions with any medications and your health conditions. The caffeine in black tea may also interfere with certain blood tests. Tell your doctor if you drink a lot of black tea.

The U.S. Food and Drug Administration (FDA) does regulate dietary supplements; however, it treats them like foods rather than medications. Unlike drug manufacturers, the makers of supplements don’t have to show their products are safe or effective before selling them on the market.
