Green tea comes from a bush in the Camellia family, which is why the official name for green tea is Camellia sinensis, which is Latin. This evergreen bush has shiny, pointed leaves that have a wonderful aroma. This particular bush also produces beautiful white flowers. Today, green tea is grown in more than 50 countries to include Argentina, Brazil, and Russia, among others.

The exciting thing about this tea is that study after study shows positive effects on the body, meaning the negative effects of green tea leaves is minimal. For instance, green tea contains powerful antioxidants that have been proven to help fight various forms of cancer, as well as tooth decay, obesity, high cholesterol, and heart disease. Because of the amazing benefits, the level of consumption for green tea has skyrocketed throughout the globe.

Now, when it comes to the negative effects of green tea leaves, we want to start with pregnant women. Although most doctors agree that a small consumption of green tea is fine but when large amounts are consumed, caffeine can increase the risk of spontaneous abortion, low birth rate, and even growth retardation. Keep in mind that these risks are associated with the beverage of green tea, as well as supplements.

EGCG molecules, which are similar to a methotrexate compound, work by fighting off cancer cells by bonding with the dihydrofolate reductase enzyme, which is good in non-pregnant women. However, in pregnant women, the negative effects of green tea leaves involves involve the epigallocatechins, otherwise known as EGCG. In this situation, EGCG can affect the way in which the body uses folate, which is vital in the prevention of neural tube birth defects.

Nursing women should also consider the negative effects of green lea leaves. Remember, green tea is high in caffeine. Therefore, a woman who is breastfeeding and consuming green tea would be passing the caffeine on to the baby. Even small amounts or green tea powder used for baking, smoothies, and other foods should be avoided while nursing a baby.

In addition, negative effects of green tea leaves would link to individuals who have allergies. In this case, someone who is caffeine sensitive could develop problems such as hives and rash from consuming green tea. With caffeine being a stimulant that affects the central nervous system, other problems could result such as insomnia, excessive urination, reduction of potassium levels, and even incontinence. Just keep in mind that if you have any concerns about negative effects of green tea leaves for you, we recommend that you talk to your doctor or a health food specialist.

Side Effects of Black Tea:

Studies of the side effects of black tea specifically are limited. However, black tea is a source of caffeine, for which multiple reactions are reported.

Caffeine is a stimulant of the central nervous system, and may cause insomnia in adults, children, and infants (including nursing infants of mothers taking caffeine). Caffeine acts on the kidneys as a diuretic (increasing urine and urine sodium/potassium levels, and potentially decreasing blood sodium/potassium levels), and may worsen urge incontinence. Caffeine-containing beverages may increase the production of stomach acid, and may worsen ulcer symptoms. Tannin in tea can cause constipation. Caffeine in doses of 250 to 350 milligrams can increase heart rate and blood pressure, although people who consume caffeine regularly do not seem to experience these effects in the long-term.

An increase in blood sugar levels may occur after drinking black tea containing the equivalent of 200 milligrams of caffeine (4 to 5 cups, depending on tea strength and cup size). Caffeine-containing beverages such as black tea should be used cautiously in patients with diabetes. People with severe liver disease should use caffeine cautiously, as levels of caffeine in the blood may build up and last longer. Skin rashes have been associated with caffeine ingestion. In laboratory and animal studies, caffeine has been found to affect blood clotting, although effects in humans are not known.

Caffeine toxicity/high doses: When the equivalent or more than 500 milligrams of caffeine are consumed (usually more than 8 to 10 cups per day, depending on strength and size of cups), symptoms of anxiety, delirium, agitation, psychosis, or detrussor instability (unstable bladder) may occur. Conception may be delayed in women who consume large amounts of caffeine. Seizure, muscle spasm, life-threatening muscle breakdown (rhabdomyolysis), and life-threatening abnormal heart rhythms have been reported with caffeine overdose. Doses greater than 1000 milligrams may be fatal.

Caffeine withdrawal: Chronic use can result in tolerance, psychological dependence, and may be habit forming. Abrupt discontinuation may result in withdrawal symptoms such as headache, irritation, nervousness, anxiety, tremor, or dizziness. In people with psychiatric disorders such as affective disorder or schizoaffective disorder, caffeine withdrawal may worsen symptoms or cause confusion, disorientation, excitement, restlessness, violent behavior, or mania.

Chronic effects: Several population studies initially suggested a possible association between caffeine use and fibrocystic breast disease, although more recent research has not found this connection. Limited research reports a possible relationship between caffeine use and multiple sclerosis, although evidence is not definitive in this area. Animal study reports that tannin fractions from tea plants may increase the risk of cancer, although it is not clear that the tannin present in black tea has significant carcinogenic effects in humans.

Drinking tannin-containing beverages such as tea may contribute to iron deficiency, and in infants, tea has been associated with impaired iron metabolism and microcytic anemia.

Side Effects of Rooibos Tea:

As rooibos has not been studied scientifically in humans, there is no information available about its safety in pregnancy or lactation or in people with kidney or liver failure. However, it is generally considered a very safe herb, and there are no known side effects, contraindications, or drug interactions.13

At the time of writing, there were no well-known drug interactions with Rooibos.

Side effects of White Tea

* none to be found, so other than the effects of caffeine with drinking large amounts of it, no side effects could be find through a Google search

* except for the impact to your pocket book. White tea right now is much more expensive than all the other teas.

Side effect of Chamomile Tea:

If you suffer from allergies to plants of the Compositae family (a large group including such flowers as daisies, ragweed, asters and chrysanthemums), you may wish to be cautious about using chamomile at first. While there have been isolated reports of allergic reactions, causing skin rashes and bronchial constriction, most people can use this herb with no problem.

The health benefits range from helping with mild symptoms to preventing severe symptoms from occurring.

During the process of oxidation, highly reactive by-products called free radicals are produced. These free radicals act on other molecules, turning them into free radicals like themselves, thus disrupting their normal functioning. It’s almost like a virus rapidly spreading. This could eventually lead to massive cell destruction, tissue damage, and even cause degenerative diseases, heart disease, like cancer, Parkinson’s disease, Alzheimer’s disease, rheumatoid arthritis, and atherosclerosis among other negative antioxidant effects.

Oxygen damage to your cells results when there are too many free radicals present inside the body. Researchers conclude that such damage may be partly responsible for the effects of aging and certain diseases.

There are certain substances in food which may play a role in protecting against this damage. Luckily, the human body comes prepared with natural defenses against these harmful free radicals.

Antioxidants are chemical substances found naturally in fruits and vegetables. Antioxidants act on free radicals, pursuing them and neutralizing them in order to stop their negative effect on the body’s healthy cells.
