Chamomile Tea: Flavor, Brewing, Buying & What the Evidence Really Says

The chamomile tea most people drink is made from German chamomile, Matricaria chamomilla (the NIH also lists the synonyms Matricaria recutita and Chamomilla recutita). It is an annual member of the daisy family, Asteraceae, native to southern and eastern Europe and now grown on every continent. The plant stands roughly 15 to 60 cm (6 to 24 in) tall and carries small flower heads with white petals around a domed yellow center, which is exactly what you see when you tip a pouch of loose chamomile into your palm.

There is a second plant sold under the same name: Roman chamomile, Chamaemelum nobile. The NIH's National Center for Complementary and Integrative Health (NCCIH) notes the two types and focuses its fact sheet on the German one, which is also the one that dominates supermarket tea bags. If a box simply says "chamomile tea," it almost always contains German chamomile; specialty sellers who use Roman chamomile usually say so on the label.

The name itself is a clue to the aroma. It comes from the Greek chamaimēlon, "earth-apple," a reference to the apple-like scent of the plant. The flowers also carry a small amount of essential oil, which turns blue when distilled because of a compound called chamazulene. That is why German chamomile is sometimes called "blue chamomile," even though nothing in your cup will look blue.

Because chamomile tea is not made from Camellia sinensis, the tea plant, it is technically a tisane or herbal infusion rather than a "true" tea. You will see both words used; our herbal tea guide explains the distinction and where chamomile sits among the other popular tisanes.

Good chamomile tea tastes mellow, floral and lightly sweet, with that apple note in the aroma and a soft, almost hay-like finish. It has none of the astringent grip of black tea, because it contains no tea tannins to speak of, and it is not sour like hibiscus. Most people describe it as soothing in flavor before they ever think about anything else.

The variation between brands is real, and it comes mostly from what is inside the bag:

• Whole flower heads keep more of their aroma than finely milled material. Loose chamomile that still looks like tiny dried daisies usually brews a rounder, sweeter cup.
• Fannings and dust (the fine powder in many standard bags) brew fast but taste flatter and can turn slightly bitter if left too long.
• Freshness matters more than people expect. The aroma lives in volatile oils, so a box that has sat open for months tastes duller than a sealed one.
• Blends change the profile entirely. Chamomile with lavender, lemon balm, mint or honey flavoring is common, and many "sleep" blends are mostly something else with chamomile as a supporting note.
• Brewing time is the variable you control. A short steep under-extracts the honeyed body and leaves only a grassy edge.

If your last chamomile tea tasted like nothing, the fix is usually a fuller steep with the cup covered, or a switch to whole flowers. If it tasted medicinal or bitter, try a fresher box, fewer flowers, or a blend with a little mint or citrus.

The Tea Association of the USA's steeping chart groups herbal teas together at 212°F (100°C) for 3 to 6 minutes, with one teaspoon of loose tea or one tea bag per 6 oz cup of water. Chamomile tea sits comfortably inside that guidance, and the full boil is not just about flavor. The UK Tea & Infusions Association advises that herbal and fruit infusions are intended to be brewed with freshly boiled water.

In practice, a reliable hot cup looks like this. Bring fresh, cold water to a full boil. Put one bag, or about a teaspoon of whole dried flowers, in a mug or pot for each 6 oz of water. Because whole flower heads are light and fluffy, a heaping teaspoon of them weighs less than a level teaspoon of dense black tea, so do not be shy with loose flowers. Pour the boiling water over, cover the cup with a saucer, and wait. Covering matters more for chamomile than for most teas, because the aromatic oils are exactly what you are trying to keep in the cup rather than in the kitchen air.

Start tasting at the 5-minute mark. Chamomile is forgiving, and if you prefer a fuller cup you can let it go to the top of the 3 to 6 minute window. Strain loose flowers through a fine mesh; the tiny florets can slip through coarse infusers. Honey and a thin slice of lemon are the classic additions, and a splash of milk works surprisingly well with whole-flower chamomile.

Chamomile tea makes a lovely iced drink, but it is not a tea you should simply drop into cold water and leave overnight unless the package specifically tells you to. The UK Tea & Infusions Association, citing the European trade body Tea & Herbal Infusions Europe, is explicit: herbal and fruit infusions labeled as cold brew products are designed to be prepared with cold water, but if a product is not labeled that way, you should always prepare it first with freshly boiled water, even if you plan to cool it and pour it over ice. Dried flowers are an agricultural product, and the boil is the step that makes the infusion safe.

So the method for most chamomile tea is "hot bloom, then chill." Brew a concentrated batch with boiling water, using roughly double the flowers for the volume, cover it and steep for the full time. Strain, let it cool on the counter for a short while, then refrigerate. Pour over plenty of ice, which dilutes the extra strength back to normal. Keep the pitcher in the fridge at or below 40°F and treat it like any other brewed drink.

If you want true cold brewing, look for a chamomile tea product sold as a cold-brew bag and follow its instructions. Our dedicated guide to cold brew herbal tea walks through both approaches and explains the safety reasoning in more depth. And if your heart is set on the fully cold, overnight style with real tea leaves, our main cold brew tea guide is where that method shines, since Camellia sinensis teas are typically handled differently from dried herbs.

Most of the disappointment people feel with chamomile tea comes from the box, not the brewing, so it is worth a minute at the shelf. Start with the ingredient list. A single-ingredient product should say chamomile flowers and nothing else; a blend should list its ingredients in descending order, so you can tell whether chamomile is the main event or a garnish. If added flavorings or sugar are present, the UK Tea & Infusions Association notes these should appear on the ingredients list.

Next, look at the form. Whole flower heads are easy to recognize: small, intact, yellow centers with some white petals still attached. They tend to cost more per cup but are the best route to the sweet, apple-like aroma. Standard chamomile tea bags are convenient and perfectly pleasant when fresh, but because the material is finely cut, it loses aroma faster once the box is opened. Pyramid bags often sit somewhere between the two.

Then think about storage. Chamomile's appeal lives in its volatile oils, which fade with air, light and warmth. Buy a size you will finish within a reasonable time, keep it in an airtight, opaque container away from the stove, and do not store it next to strong spices or coffee, since dried flowers absorb odors readily. If a pouch smells of almost nothing when you open it, it will brew a cup of almost nothing.

Finally, if you are allergy-prone, read the next section before you buy. The same daisy-family heritage that gives chamomile its charm is also the reason some people should approach it carefully.

Chamomile has a long reputation. NCCIH notes that it was described in ancient medical writings and was an important medicinal herb in ancient China, Egypt, Greece and Rome, and that today it is promoted for everything from the common cold and indigestion to anxiety and insomnia. The honest summary of the modern evidence is more modest than the reputation.

According to NCCIH, studies of chamomile for specific conditions have not produced sufficient reliable evidence to rate clinical usefulness. Some preliminary studies suggest a chamomile dietary supplement might help with generalized anxiety disorder, but that is a supplement, not a mug of tea. On sleep specifically, NCCIH says there is very little information, and that a 2019 review found one study on insomnia, which showed no benefit. That does not stop a warm, caffeine-free drink from being a pleasant part of an evening routine; it simply means the comfort of chamomile tea is the ritual, not a proven sleep effect.

On safety, NCCIH describes chamomile as likely safe when used orally in amounts commonly found in teas and other foods. Side effects are uncommon but can include nausea, dizziness and allergic reactions, including severe ones. People allergic to related plants such as ragweed, chrysanthemums, marigolds or daisies are more likely to react. NCCIH also notes chamomile might have some estrogen-like effects, possible interactions with birth control pills, warfarin and some other drugs, and that little is known about its safety during pregnancy or breastfeeding.

Tea is a beverage, not a treatment. If you take any medication, have an allergy history, are pregnant, or are drinking chamomile hoping to manage a health condition, talk with your doctor or pharmacist first.

Seen plainly, chamomile tea earns its place for three practical reasons. It has no caffeine: USDA FoodData Central lists brewed chamomile at 0 mg caffeine and about 1 calorie per 100 g, which makes it one of the few warm drinks you can have at any hour without thinking about your caffeine total. Chamomile tea also has a gentle flavor that does not need sugar to be enjoyable. And it is quick, needing only a kettle and five minutes.

That combination makes it a natural anchor for a wind-down habit. Many people use the act of boiling water and waiting for the steep as a signal that work is over, the same way others use a short walk or a book. If that idea appeals, best teas for sleep compares chamomile with other caffeine-free options such as rooibos and peppermint.

A few small habits make the cup better. Use a lidded mug or a small pot so the aroma stays in. Drink chamomile tea warm rather than scalding, which lets the delicate honey and apple notes come through. If you like it sweet, a teaspoon of honey is enough; chamomile has its own soft sweetness. And if you find yourself reaching for it in summer, brew a concentrated pot after dinner, chill it overnight, and you have a ready iced drink for the next afternoon, made the safe way with a proper boil first.
