Chamomile tea is one of the most consumed herbal teas in the world - and for good reason. For thousands of years, civilisations from ancient Egypt to medieval Europe have used chamomile flowers as a natural remedy. Today, modern science is catching up, and what it's finding is genuinely impressive. Whether you drink it before bed, after meals, or simply because you love the gentle floral taste, here are seven health benefits of chamomile tea backed by research.
What Is Chamomile Tea?
Chamomile tea is an herbal infusion made from the dried flowers of the chamomile plant — most commonly Matricaria chamomilla (German chamomile) or Chamaemelum nobile (Roman chamomile). Unlike green or black tea, chamomile contains no caffeine, making it a safe choice at any time of day, including for those who are caffeine-sensitive.
The flowers are rich in apigenin, a flavonoid antioxidant that is largely responsible for chamomile's calming and anti-inflammatory effects. The tea also contains bisabolol, chamazulene, and a range of other plant compounds that contribute to its health benefits.
1. Chamomile Tea May Help You Sleep Better
This is chamomile's most famous benefit — and the science backs it up. Apigenin, the primary antioxidant in chamomile, binds to specific receptors in the brain that may promote sleepiness and reduce insomnia.
A 2017 study published in Phytomedicine found that elderly people who consumed chamomile extract for four weeks had significantly better sleep quality than those who did not. A separate study of new mothers found that those who drank chamomile tea for two weeks reported better sleep quality and fewer symptoms of depression related to sleep deprivation.
Chamomile is not a sedative — it won't knock you out — but its gentle calming effect can make falling asleep easier, especially when paired with a proper wind-down routine. Brew a cup of Dilmah Pure Chamomile Flowers 30 minutes before bed.
2. It Can Help Reduce Anxiety and Stress
Chamomile has been used as a natural anti-anxiety remedy for centuries, and modern clinical trials are validating what traditional healers observed long ago.
A landmark study from the University of Pennsylvania found that chamomile extract significantly reduced generalised anxiety disorder (GAD) symptoms in participants over an eight-week period. Importantly, the benefits persisted even after participants stopped taking the extract.
The mechanism is largely linked to apigenin's interaction with GABA receptors in the brain — the same receptors targeted by anti-anxiety medications, but through a much gentler pathway. If you're managing daily stress, replacing your afternoon coffee with a cup of chamomile tea is a simple, evidence-supported swap.
3. Chamomile May Support Digestive Health
One of chamomile's traditional uses has been as a digestive remedy, and this is an area where the research is particularly strong. Chamomile has antispasmodic properties — meaning it can help relax the smooth muscle of the digestive tract. This makes it useful for easing cramps, bloating, indigestion, and irritable bowel symptoms.
Bisabolol, one of chamomile's active compounds, has been shown to reduce gut inflammation and support the integrity of the intestinal lining. A cup of chamomile tea after a heavy meal is not just a pleasurable ritual — it's a genuinely helpful digestive aid.
4. It Has Powerful Anti-Inflammatory Properties
Chronic inflammation is linked to almost every major disease — from heart disease and diabetes to arthritis and certain cancers. Chamomile is rich in flavonoids and terpenoids — plant compounds with demonstrated anti-inflammatory activity.
Chamazulene, the compound that gives chamomile essential oil its distinctive blue colour, is particularly noted for its anti-inflammatory effects. Research suggests that regular chamomile consumption may help reduce markers of systemic inflammation.
5. Chamomile Tea May Help Regulate Blood Sugar
This is one of chamomile's lesser-known but increasingly researched benefits — particularly relevant for the millions of Americans managing pre-diabetes or type 2 diabetes.
A notable Iranian trial of 64 participants with type 2 diabetes found that drinking chamomile tea three times daily with meals led to significant reductions in blood sugar levels, insulin, and HbA1c compared to drinking water. The mechanism appears to involve chamomile's antioxidants inhibiting an enzyme called aldose reductase, which plays a role in blood sugar regulation.
This doesn't mean chamomile tea is a treatment for diabetes — it's not. But as a complementary habit alongside a balanced diet, it shows genuine promise.
6. It May Benefit Heart Health
Chamomile contains flavonoids called quercetin and apigenin, which have been associated with improved cardiovascular outcomes in population studies. A long-term study from the Netherlands found that high flavonoid consumption was associated with a significantly reduced risk of coronary heart disease mortality.
Chamomile may also have a mild blood-pressure-lowering effect, though this is based primarily on animal studies and requires further human research to confirm.
7. Chamomile Has Antibacterial Properties
Studies have found that chamomile extract can inhibit the growth of several bacteria, including Staphylococcus aureus and Streptococcus mutans (the bacterium responsible for dental cavities). Its antimicrobial properties add another layer of value to what is already a remarkably versatile plant.
How to Get the Most Out of Your Chamomile Tea
To maximise the health benefits of chamomile, a few brewing tips matter:
• Use whole chamomile flowers rather than powdered tea bags where possible — more of the active compounds are preserved in the whole flower.
• Brew at 90–95°C (194–203°F) — just off the boil — for 5 minutes, covered. The cover prevents volatile aromatic compounds from escaping with the steam.
• Drink 1–3 cups per day to experience meaningful benefits. The research benefits tend to be dose-dependent.
• Do not add milk — dairy proteins may bind to some of chamomile's polyphenols and reduce their bioavailability. A small amount of honey is a lovely addition.
Who Should Be Cautious with Chamomile?
Chamomile is generally considered very safe for most adults. However:
• People with allergies to plants in the Asteraceae family (ragweed, chrysanthemums, daisies) may react to chamomile.
• Pregnant women should consult their doctor before drinking chamomile regularly.
• Chamomile may interact with blood-thinning medications like warfarin — speak to your doctor if this applies to you.
