Side effects of Green tea
Effects of caffeine
- Compared to coffee, green tea has a lower concentration of caffeine. Excessive consumption can cause agitation, a faster heartbeat, anxiety, trouble sleeping, and irritability.
- Some people may have digestive problems like upset stomach, diarrhea, or cons when having a green destination. This is caused by the tannins, which may impact the digestive system.
Iron absorption interference
- Green tea contains catechins, which bind to iron and possibly prevent the body from absorbing as much of it. For those who depend on plant-based sources of iron or have iron deficiency, this can be a cause for concern.
- A slightly increased risk of osteoporosis has been linked to excessive consumption, especially if it is eaten in large quantities with meals. This is due to the possibility that green tea could prevent the body from properly absorbing calcium.
- Green tea or one of its components may cause allergies in certain persons. Since allergic responses can range in intensity and come with symptoms, it is best to get medical help immediately.
Selecting, preparing, using, and storing Green tea
- For the most incredible flavor and aroma, choose premium loose-leaf green tea. Look for tea with intact leaves that are fresh.
- Think about the type of green tea you like. Sencha, Matcha, Gyokuro, Dragon Well, and Gunpowder are just a few variations, each with unique features.
Green tea consumption
- The majority of consumers drink it hot. It can be used in baking and cooking to give dishes a mild tea flavor.
- Some people include the extract in supplements for cosmetics.
- Avoid using boiling water because green tea is sensitive. The ideal water temperature is between 70 and 80 degrees Celsius, or 160 degrees Fahrenheit. Too-hot water can make the tea taste bitter when brewed.
- Depending on the type and your preferences, steep it for between 1 and 3 minutes. A more potent, more bitter flavor may result in longer steeping times.
The ratio of tea to water
- For every 8 ounces (240 ml) of water, use around one teaspoon of loose-leaf green tea. Depending on the strength you desire, change the amount.
- The leaves can be brewed in a teapot, cup, or infuser basket. After the desired brewing period, strain or get rid of the leaves.

- It has chemicals with potential anticoagulant effects and vitamin K. If you use any blood thinners, such as aspirin or warfarin, stay away from green tea.
- You should restrict your green tea intake if you are caffeine-sensitive or using medications that can interact with caffeine, such as some stimulants, asthma treatments, or antidepressants.
Drugs to lower blood pressure
- Suppose you use any hypertension medications, such as beta-blockers or calcium channel blockers. In that case, it is advised that you regularly check your blood pressure because it may cause your blood pressure to decrease.
Medications affected by liver enzymes
