Tea and Life

Chamomile tea has been used as a medicinal herb for thousands of years — in ancient Egypt, ancient Greece, and medieval Europe. Today, it's the most widely consumed herbal infusion in the world. The science behind its reputation is more solid than for most herbal teas, though some claims are better supported than others. Here's an honest look at what chamomile actually does.

The Key Compound: Apigenin

Chamomile's primary active compound is apigenin, a flavonoid that binds to GABA receptors in the brain — the same receptors targeted by many anti-anxiety medications, but with much milder effect. This is the mechanism behind chamomile's documented calming and sleep-promoting properties. Unlike pharmaceutical GABA modulators, chamomile's apigenin effect is gentle and does not produce dependence.

Sleep and Relaxation

This is chamomile's best-documented benefit. A randomised controlled trial published in the Journal of Advanced Nursing found that postnatal women who drank chamomile tea for two weeks had significantly better sleep quality and fewer symptoms of depression compared to a control group. A second study in older adults found that 270mg chamomile extract twice daily for 28 days significantly improved sleep quality and reduced nighttime waking.

Chamomile won't work as fast or as powerfully as a pharmaceutical sleep aid, but for mild sleep difficulty or evening wind-down, a cup 30–45 minutes before bed has genuine evidence behind it.

Digestive Health

Chamomile has anti-spasmodic properties — it relaxes smooth muscle, including the smooth muscle lining the digestive tract. This is why it's traditionally used for stomach cramps, bloating, and irritable bowel symptoms. A few small clinical studies support this, particularly for infant colic and mild IBS symptoms in adults. The evidence is less robust than for sleep, but the mechanism is plausible and consistent.

Anti-Inflammatory and Antioxidant Properties

Chamomile contains several other flavonoids beyond apigenin, including luteolin and quercetin, which have documented anti-inflammatory activity in laboratory studies. Whether the concentrations in brewed tea are sufficient to produce meaningful anti-inflammatory effects in humans is less clear — the in-vitro evidence is stronger than the clinical evidence. What is clear: chamomile tea contains meaningful quantities of antioxidants that contribute to overall dietary antioxidant intake.

Anxiety and Stress

A longer-term study at the University of Pennsylvania followed participants with generalised anxiety disorder who took chamomile extract for 8 weeks. The chamomile group showed significant improvement in anxiety symptoms compared to placebo, and this benefit was sustained in a follow-up maintenance phase. The evidence here is more convincing than for most herbal anxiety remedies.

Blood Sugar

Animal studies and a small number of human trials suggest chamomile may have modest blood sugar-lowering effects. One study in people with type 2 diabetes found that chamomile tea consumed after meals was associated with reduced blood glucose levels compared to water. This is preliminary evidence and should not be used as the basis for managing diabetes, but it's consistent with chamomile's anti-inflammatory mechanism.

How to Brew Chamomile Tea

Chamomile is typically sold as dried flowers or in tea bags. For the best flavour and highest apigenin content:

• Use fresh, just-boiled water (90–95°C)
• Use 1–2 teaspoons of dried flowers per 250ml, or one quality tea bag
• Steep for 5–7 minutes, covered (covering the cup retains volatile aromatic compounds)
• Strain and drink plain, or with a small amount of honey

Don't over-steep — beyond 8–10 minutes, chamomile can become slightly bitter. The optimal steep time balances apigenin extraction with palatability.

A Note on Pairing with Nepali Tea

Chamomile is caffeine-free — a good evening option when you want a warm drink without the caffeine of true tea. If you enjoy both chamomile and true teas, Nepal Hills' Floral White Tea is the closest equivalent in terms of delicacy and floral character — though it does contain low levels of caffeine (15–25mg per cup). The Tea Sampler Kit is a good way to explore both white and green teas from Nepal's high-altitude estates if chamomile is your gateway into the herbal world.

Frequently Asked Questions

Can I drink chamomile tea every day?
Yes — daily chamomile consumption is safe for most people. The exception: people with allergies to plants in the Asteraceae family (ragweed, chrysanthemums, daisies) may react to chamomile. Pregnant women should consult a physician, as chamomile has mild uterine-stimulating properties at high doses.

How long does it take for chamomile tea to help with sleep?
The best evidence suggests a consistent effect after 2 weeks of nightly use. Single-dose effects are reported by many people (30–45 minutes before bed) but the research is stronger for consistent daily consumption over time.

Is chamomile better than melatonin for sleep?
They work differently. Melatonin directly signals circadian timing and works well for jet lag and shift work sleep disruption. Chamomile's apigenin effect is more like a mild sedative — better for general wind-down and stress-related sleep difficulty. Many people find chamomile sufficient; others need the stronger effect of melatonin for specific situations.

Does chamomile interact with medications?
Potentially, yes. Chamomile has mild anticoagulant properties and can theoretically interact with warfarin or other blood thinners. It may also potentiate the effect of sedative medications. If you're on regular medications, check with your physician before adding chamomile tea as a consistent daily practice.

Roman vs German chamomile — is there a difference?
Yes, but it's minor for most purposes. German chamomile (Matricaria chamomilla) is more widely used in research and contains higher levels of apigenin and azulene. Roman chamomile (Chamaemelum nobile) has a slightly sweeter, more apple-like flavour. Most commercial chamomile tea is German chamomile.
