Side Effects and Detriments
While earl grey tea is full of nutrition, nutrient-rich, and is safe for most people, drinking too much may cause some negative side effects, especially due to the essential bergamot orange oil.
Earl grey tea is considered a black tea because of the similarity in ingredients used. It’s also flavored with oil from essential bergamot orange, which will lead to additional side effects.
1. Bergamot Essential Oil Can Cause Toxicity
Drinking large amounts of earl grey tea may cause you to ingest too much bergamot oil.
According to the Washington University Neuromuscular Disease Center, bergamot contains a toxin called bergapten, which means that if you consume too much it can be harmful to you.
It may affect potassium absorption in certain neurons and lead to muscle twitches, cramping in the hands and legs, may cause prickling or burning sensations, pressure in the eyes or blurry vision.
The center notes that these symptoms generally disappear within a week of discontinuing earl grey tea. If you experience any of these effects, however, see your doctor for a diagnosis and treatment options.
2. Issues with Iron Absorption
Earl Grey Tea contains tannic and gallic acids, two compounds that interfere with the absorption of the nonheme iron found in plant foods such as beans and leafy greens.
According to Marla Reicks, nutritionist at the University of Minnesota states, “Depending on how much of these acids are in your cup, which varies by brand, strength, and steeping time, drinking tea with a meal may reduce iron absorption by up to 75 percent”.
To ensure proper iron absorption throughout your meals, it’s optimal to drink between meals and not while eating them.
3. Possible Overdose of Caffeine
Like all other natural teas, earl grey is caffeinated but more so than other non-herbal teas. A stimulant that acts on the central nervous system, that kept at a low-medium dosage can prove useful.
Up to 5 cups of tea per day is considered moderate intake, but you be too caffeinated if you consume tea on top of everything else you might eat throughout the day such as cocoa powder (chocolate), coffee, or sodas (of which you shouldn’t be having).
Drinking too many non-herbal teas such as earl grey tea, green tea, black tea, and oolong tea causes increased caffeine intake, just like coffee. This may lead to anxiety, heart palpitations, tremors, and sleeplessness when consuming too much caffeine.
Some hypersensitive people may experience these side effects after drinking just a small amount of tea or coffee. To test your body’s tolerance to caffeine it’s best to reduce how frequently and how much you consume slowly, over time.
If drinking earl grey or any other teas is something you do daily, you may also become dependent on the energy buzz and could experience withdrawal symptoms such as headaches and irritability once you stop.
In summary, earl grey tea has a very wide range of health enhancements when consumed in moderation. It’s also possible to suffer a minor set of side effects when it’s taken too often.
