Chamomile

Chamomile has been examined in humans across several health areas. Evidence ranges from solid to early-stage; framing below reflects that range honestly. Sleep and relaxation This is chamomile's best-studied territory in humans. In one randomized controlled trial (an experiment where participants are randomly assigned to a treatment or a comparison group), postpartum women with sleep difficulties who drank chamomile tea daily for two weeks reported meaningfully better sleep quality and lower symptoms of low mood compared with a control group — although benefits faded after the tea was stopped. A separate small trial in older adults found that an oral chamomile extract taken over about a month improved sleep quality scores versus a placebo (an inactive comparison treatment). For mild anxiety, standardized chamomile extracts (stronger than ordinary tea) reduced anxiety scores in randomized, double-blind (neither participant nor researcher knew who got what) trials. Together, these studies support chamomile as a gentle wind-down beverage — though they do not establish it as a treatment for insomnia or anxiety disorders. Digestive health and the gut Chamomile has a centuries-long tradition as an after-dinner digestive. Modern human research specifically on chamomile tea for adult digestion is sparse; much of the clinical data involves combination herbal formulas. The likely mechanism is a mix of the warm liquid itself, mild bitterness that stimulates digestive juices, and bisabolol's antispasmodic (muscle-tension-easing) properties on smooth muscle in the gut wall. Research supports describing chamomile as a gentle, calming after-meal tisane that may ease the occasional feeling of fullness or abdominal discomfort — not as a treatment for diagnosed gastrointestinal conditions. Blood sugar and metabolic health Several small randomized trials in adults with type 2 diabetes (a condition where blood sugar regulation is impaired) have tested chamomile tea as an add-on to standard care. Participants drinking chamomile tea two to three times daily after meals for around eight weeks showed modest improvements in fasting blood glucose (blood sugar measured after a period without eating), HbA1c (a marker of average blood sugar over about three months), and blood lipids (fats in the blood including cholesterol and triglycerides) compared with controls. These were tea-strength infusions, not high-dose supplements. Research suggests chamomile may be a supportive lifestyle choice alongside evidence-based medical and nutrition care — it is not a substitute for prescribed diabetes management. Inflammation and antioxidant support Chamomile's flavonoids and terpenoids show anti-inflammatory and antioxidant activity in cell and animal studies. In the metabolic trials above, improvements in oxidative stress markers were noted as secondary outcomes, suggesting a real but modest antioxidant effect from regular tea drinking. Evidence does not support chamomile as a primary intervention for inflammatory conditions, but it can fit comfortably in a plant-forward, anti-inflammatory eating pattern. Hormones and cycle health Small studies have explored chamomile for premenstrual symptoms and sleep disturbance linked to postpartum hormonal changes. Results are preliminary, often involve other herbs, and no direct hormonal effects have been measured. Chamomile is best described as a comforting botanical that may ease the experience of cyclical or life-stage changes (think: a calming evening cup during a difficult PMS week) rather than a direct hormone modulator.

Chamomile is remarkably versatile. Here is how the main forms compare: Loose dried flowers — Best for culinary creativity. Whole or coarsely cut flower heads deliver the richest aroma, make visual inspection easy, and can be used in teas, cold brews, syrups, poaching liquids, and infused milks. Store in an airtight container away from light and heat; quality is best within one to two years. Tea bags — The most convenient everyday option. Pre-portioned and consistent, though the finer particle size may produce a slightly different flavor. Great for routine hydration and evening rituals. Culinary infusions (syrups, infused milks, vinegars) — Steeping dried flowers in warm simple syrup, oat milk, or light vinegar unlocks chamomile's floral, apple-honey character for use in desserts, baked goods, dressings, and mocktails. Culinary flavorings and extracts — Concentrated chamomile flavor preparations exist for consistent, measurable flavoring in professional or high-volume cooking contexts; useful but generally beyond the scope of an everyday apothecary kitchen. Buying tip: Look for whole or lightly broken flower heads with a clear golden-yellow color and a distinct fresh, floral scent — not musty or hay-like. Organic labeling reduces the chance of pesticide residue on flowers, which are often used unpeeled and unprocessed.

Chamomile is not a true tea from the Camellia sinensis plant; it is an herbal infusion, or tisane, made from the dried flower heads of Matricaria chamomilla or Chamaemelum nobile. It has been brewed for thousands of years across Europe, North Africa, and the Middle East for its flavor and soothing properties.

Chamomile tea may help with sleep and relaxation because it contains apigenin, a flavone that can bind to specific receptors in the brain associated with calming effects. This active compound, along with aromatic terpenoids, is a key driver of the plant's mild sedative-like benefits.

To prepare classic chamomile tea, steep one to two teaspoons of dried flowers in 90–95 °C water for five to seven minutes. Avoid using a full rolling boil or steeping for too long, as this can increase the bitterness of the botanical infusion.

Chamomile contains natural coumarins, which are compounds that may enhance the effects of blood-thinning medications like warfarin, aspirin, or clopidogrel. While occasional cups are generally safe, those on anticoagulants should avoid heavy or concentrated use without consulting a prescriber.

People with allergies to the Asteraceae family—including ragweed, chrysanthemums, marigolds, or daisies—have a higher risk of an allergic reaction to chamomile. Symptoms can range from mild itching and hives to more serious responses, so a patch test is recommended for topical use.

Cooking with chamomile works well when paired with honey, lemon, vanilla, oat milk, or stone fruits like peaches and apricots. Its natural apple-like undertones make it an excellent base for simple syrups, poaching liquids, custards, and even salad dressings.

You can make cold brew chamomile by steeping two tablespoons of dried flowers in 500 mL of cold filtered water for six to eight hours in the refrigerator. This cold extraction method results in a clean, delicate floral flavor with very little bitterness compared to hot steeping.

Chamomile grows as a summer annual or perennial across most of the United States, typically blooming from May through September. While it thrives in USDA hardiness zones 3 through 9, gardeners in hotter regions like the South should plant it in spring to avoid the intense mid-summer heat.

In the U.S., you can find chamomile tea at major retailers like Walmart, Kroger, and Whole Foods, while fresh or high-quality dried flowers are common at local farmers markets. For organic varieties, look for the USDA Organic seal to ensure the flowers were grown without synthetic pesticides or fertilizers.

German chamomile is the most common variety grown in U.S. home gardens because it is a hardy self-seeding annual that handles various American climates well. Roman chamomile is often used in the U.S. as a perennial groundcover or "herbal lawn" in temperate regions like the Pacific Northwest.
