Chamomile tea is commonly known to relieve nausea and soothe the stomach, but drinking too much can have the opposite effect by overloading the digestive system.

Additionally, chrysanthemum tea that is too strong or drunk while it is too hot can irritate the stomach lining, leading to nausea, discomfort, or mild stomach pain.

Other factors such as interactions with medications being taken, effects on blood pressure or allergic reactions can also be the cause of nausea in some people.

However, drinking chamomile tea in large enough quantities to cause serious side effects is very rare, but users should still moderate their consumption, avoid drinking on an empty stomach, and check for allergies if they have a sensitive constitution to enjoy the maximum benefits that this tea brings.

Drinking large amounts of chamomile tea can cause nausea and vomiting.

2. Allergic reactions

People allergic to the Asteraceae family, which includes ragweed, chrysanthemums, marigolds, and daisies, are more likely to have an allergic reaction to chamomile tea, which can cause nausea and other symptoms such as skin rashes.

However, an allergic reaction to Roman chamomile can lead to severe anaphylaxis and anaphylactic shock if too much of this flower tea is consumed.

3. Sleepiness from drinking too much chamomile tea

Chamomile tea causes drowsiness mainly because the flavonoid apigenin in the tea binds to GABA receptors in the brain, creating a mild sedative and relaxing effect, helping to reduce anxiety and induce sleep.

Apigenin, a powerful antioxidant found in chamomile, acts on benzodiazepine receptors in the brain, similar to how some anti-anxiety medications work. This interaction reduces arousal and promotes relaxation, which can lead to sleepiness.

Because of this effect of chamomile tea, people who are taking sedatives should be careful when drinking it, especially not drinking large amounts to avoid excessive drowsiness, especially with jobs that require alertness such as driving...

4. Increased risk of bleeding

Chamomile tea may also be dangerous for people taking blood thinners or other medications that are metabolized by the liver.

This is because Roman chamomile contains natural coumarin compounds, which can enhance the effects of blood thinners like warfarin and increase the risk of bleeding if consumed in large amounts.

Therefore, anyone taking prescription medications should consult their doctor before drinking chamomile tea regularly.

5. Effects on contraception

Drinking too much chamomile tea may also affect the effectiveness of birth control pills. Research suggests that chamomile may reduce the effectiveness of birth control pills and may worsen conditions that make the body sensitive to estrogen, including breast or uterine cancer.

There is not enough data on the safety of chamomile during pregnancy or breastfeeding, so pregnant and breastfeeding women should exercise caution.

6. How much chamomile tea is safe to drink?

To avoid these side effects, limit your daily intake of chamomile tea. There is no specific limit, but most recommendations suggest that 1-3 cups (about 700ml) per day is safe for most healthy adults.

In addition, it is necessary to pay attention to the sensitivity level of each person, especially in cases of taking medication or having health problems, so observe the body and adjust the amount of tea accordingly.
