While drinking tea is mostly considered healthy for adults, a few side effects should be considered. Most of the side effects of Camellia sinensis tea intake can be avoided when drinking only moderate amounts.

Nevertheless, this drink should also be avoided by certain individuals with an allergy to these tea ingredients.

Caffeine is the key compound in this tea which causes sensitive people to react. Recognizing that most of these side effects can be due to the small amount of caffeine in green tea is significant.

Generally, when you drink a cup of coffee without these symptoms, it is unlikely that you will encounter any side effects from drinking Camellia sinensis tea.

These Sides effects are:

  • Stomach Problems: When brewed too strongly or eaten on an empty stomach, green tea can cause stomach irritation. Green tea contains tannins that can increase your stomach’s acid content. Excess acid, including constipation, acid reflux, and nausea, can contribute to digestive problems. Green tea can also cause diarrhea due to its laxative effect when drunk in large quantities.
  • Headaches: Green tea in some individuals can cause headaches as it contains caffeine. If you are sensitive to caffeine, stop drinking green tea.
  • Anemia and Iron Deficiency: Green tea contains antioxidants that prevent the human body from absorbing iron. Research shows that this side effect can pose a particular risk to people suffering from anemia or other diseases with iron deficiency. Add lemon to your tea to prevent this side effect. Through lime, vitamin C facilitates the absorption of iron, counteracting this side effect. Instead, one hour before or after a meal, you can eat green tea.

  • Dizziness and Convulsions: If drunk in large quantities, the caffeine in green tea can cause you to feel dizzy or lightheaded. Caffeine reduces blood supply to the brain and central nervous system, leading to sickness in motion. In rare cases, green tea consumption may result in seizures or confusion. In some cases, tinnitus may also increase the intake of green tea, known as ringing in the ears. Do not drink green tea if you suffer from tinnitus.
  • Vomiting: Nausea and vomiting can result in excessive amounts of green tea. This is because green tea contains tannins associated with vomiting and constipation due to the binding of proteins in the intestines.
  • Problems Sleeping: Green tea contains an anti-sleeping compound: caffeine. Green tea contains only small quantities of caffeine, but may still cause sleeping problems for people who are sensitive to caffeine. This is because chemical compounds in green tea prevent hormones such as melatonin from releasing that aid in sleep. Green tea also includes l-theanine, a chemical which helps calm down but also increases alertness and focus— something that can disrupt many people’s sleep.
  • Risks for Pregnancy and Child Use: Throughout pregnancy tannins, caffeine and tea catechins were all linked to increased risks. Experts say that green tea is safe during pregnancy and breastfeeding in small amounts— no more than 2 cups per day. To order to monitor your consumption to conjunction with your doctor, caffeine is transmitted by breast milk to children. Drinking more than 2 cups a day can lead to childhood miscarriage and birth defects. Make sure that your intake of caffeine is less than 200 milligrams a day.
  • Bleeding Disorders: Camellia sinensis tea can, in rare cases, cause bleeding disorders. Camellia sinensis tea compounds decrease fibrinogen levels, a protein which helps clot blood. Green tea also stops fatty acids from oxidizing, which can lead to a thicker consistency in the blood. Do not drink green tea if you suffer from a blood clotting disorder.
  • Irregular Heartbeat and Blood Pressure: The intake of green tea can increase high blood pressure, making it a dangerous drink if you have heart disease. This side effect is uncommon and it takes more work to investigate the exact compounds behind the increase in blood pressure. Although research shows that drinking tea can help lower blood pressure, it has been shown in some studies that Camellia sinensis tea actually increases blood pressure. One study found that green tea more than caffeine alone increased blood pressure.
  • Bone Disease: Excessive consumption of this tea in sensitive individuals increases the risk of bone disease such as osteoporosis. Green tea compounds impede calcium absorption, contributing to bone health degradation.
  • Liver Disease: Green tea supplements and high green tea intake can result in damage to the liver and disease. Doctors think this is due to a caffeine build-up that can strain the liver. Stop drinking more than 4 to 5 cups of the tea every day to avoid this side effect.

While there are many side effects to be reported, when used in moderation, Camellia sinensis tea is considered safe by the FDA. Most of these negative side effects are caused by the amount of caffeine and happen only when the beverage is ingested in large quantities.

If you are sensitive to caffeine, stick to recommended levels and avoid green tea. If you have any conditions that predispose you to side effects, consult your doctor before you drink this tea.

How To Prepare Camellia sinensis Tea With Leaves

how to prepare tea with leaves

Preparing Camellia sinensis tea is different from making black tea at home. You have to take a few simple steps. When making this tea, bear in mind that if the tea leaves are steeped in more than 90 ° C steam, the tea becomes bitter. So, soak it in not-too-hot water.

Here are the steps to brew the leaves of Camellia sinensis.


  1. Green tea leaves. You can also use green tea pearls
  2. Cup
  3. Tea strainer (clean and dry)
  4. 1 cup of water
  5. Stainless steel pot

Preparation Procedures

  1. Take one tablespoon of Camellia sinensis tea leaves. If you want to make more than a cup of the tea, take 1 teaspoon of green tea leaves for each cup. So, take 4 teaspoons of the leaves for 4 cups of Camellia sinensis tea.
  2. Put the leaves in a strainer/sieve and keep away.
  3. Steam the water with a pot/pan of stainless steel. If instead, you would like to use a glass teapot, go ahead. The ideal temperature is 80 ° C to 85 ° C, so keep an eye on the water to make sure it doesn’t boil. If it starts to boil anyway, just turn off the gas/heat and let it cool down for a little bit (say, 30-45 seconds).
  4. Next, place the sieve/strainer over the cup or mug and pour the hot water into the cup and for 3 minutes let the tea steep. This is the move we must be very careful about. Not everyone likes their strong tea, so to test if the tea is right, hold a handy spoon and drink a teaspoon every 30-45 seconds to find out if the taste is right for you.
  5. Replace the sieve now and put it aside. You can add 1 teaspoon of honey if you want. Stir in the honey and cool the drink for a couple of seconds. Enjoy your tea!
