You were exhausted on the couch. You brushed your teeth, got into bed, and suddenly your brain wanted to revisit something awkward you said in 2009. Somewhere between flipping the pillow and calculating how many hours you have left, you remember the chamomile tea in the kitchen. Could a little flower help?

Chamomile contains apigenin, a plant compound that’s getting attention as a natural sleep aid. You can find it in foods you already eat, in herbal tea, and in capsules sold specifically for bedtime. What you can reasonably expect depends on which form you’re talking about and whether you’re dealing with the occasional restless night or a sleep problem that keeps coming back.

1 Apigenin is already in your kitchen

Apigenin is a flavonoid, one of many naturally occurring compounds found in plants. Chamomile flowers contain it, and so do parsley, celery, celery seed, and dried oregano. That sprig of parsley on the side of your plate has been quietly doing more than posing for the picture.

If you want to include more of these foods, try fresh parsley in a lemony salad dressing, celery in soup, or dried oregano on roasted vegetables. Enjoy them for what they bring to the meal. Researchers haven’t established a serving of parsley or celery that improves sleep, so there’s no bedtime target to hit. Your salad can stay a salad.

2 Scientists are studying how it might affect the brain

One reason apigenin caught researchers’ attention is its possible interaction with receptors for GABA, a chemical messenger that helps dial down activity in the nervous system. Lab and animal studies suggest apigenin may influence some of those receptors. That gives researchers a plausible reason to investigate its effects on relaxation and sleep.

There’s a long way from a receptor in a lab to a person waking up rested on Tuesday. Human trials would need to measure outcomes people actually care about, such as how long it takes to fall asleep, how often they wake up, and whether they feel better the next day. A possible mechanism is the beginning of that investigation.

3 Chamomile research offers a few encouraging clues

In 2024, Asma Kazemi and colleagues reviewed 10 chamomile studies involving 772 participants. The review found signs that chamomile may improve perceived sleep quality and help with nighttime awakenings. Across the studies, the researchers found no clear improvement in total sleep time, the percentage of time in bed spent asleep, or daytime functioning.

Those are different outcomes. If you usually wake up several times, waking up less often could feel meaningful even if you log about the same number of hours. If your biggest struggle is falling asleep in the first place, a finding about nighttime awakenings answers a different question. It also matters that the studies used different preparations and included different groups of people. An average across those studies can’t tell you how your own cup of tea will perform.

4 The results are less convincing for chronic insomnia

In a University of Michigan pilot trial, researchers randomly assigned 34 adults with chronic insomnia to take a standardized chamomile extract or a placebo for 28 days. Their sleep diaries showed no statistically significant differences between the groups in how quickly they fell asleep, how long they slept, how often they woke up, or how they rated their sleep quality.

A small trial can miss a modest benefit. It still gives us a reason to be careful about sweeping claims, especially when a product promises to solve persistent insomnia. The people in that study had been struggling for at least 6 months. That’s a different situation from a few restless evenings after a stressful week. If sleep trouble regularly spills over into your work, mood, or ability to get through the day, the pattern deserves attention on its own.

5 A cup of tea and a capsule are different experiments

Chamomile contains apigenin alongside other plant compounds. Researchers who study chamomile tea or a whole-plant extract are studying that mixture. Even when participants sleep better, the trial can’t tell us how much of the change came from apigenin alone.

A capsule labeled “50 mg apigenin” gives you a number to read. Human sleep research has yet to establish an effective dose of isolated apigenin or a reliable bedtime schedule for taking it. And the amount you get from a cup of tea depends on the product and how it’s brewed. There’s no reliable conversion from a mug of chamomile to the capsule you saw online.

6 Allergies and medications matter, even with herbal tea

The National Center for Complementary and Integrative Health considers chamomile likely safe in amounts commonly found in tea and food. It also says allergic reactions are more likely in people allergic to related plants such as ragweed, daisies, chrysanthemums, or marigolds. If that sounds like your allergy list, ask a clinician before trying it.

Interactions with warfarin, a blood thinner, have been reported. The center also flags possible interactions with sedatives and notes that little is known about chamomile’s safety during pregnancy or breastfeeding. If you take medication, bring the tea or supplement label to your pharmacist. That gives them something specific to check, especially if it’s a blend with several ingredients.

7 Give the bedtime ritual some of the credit

If chamomile is a good fit for you and you enjoy it, try a plain cup while you’re winding down. Brew it according to the package, dim the lights, and give yourself something quiet to do while you sip. A few pages of a book, a short prayer, or writing tomorrow’s to-do list can help close out the day. If a big mug sends you straight to the bathroom at midnight, a smaller cup earlier in the evening may suit you better.

Pay attention to what you’re actually hoping will improve. Is it easier to fall asleep? Are you waking up less often? Do you feel more rested in the morning? A few notes the next day can tell you more than one especially good or bad night. If sleep trouble persists and affects your daytime life, ask about cognitive behavioral therapy for insomnia, often called CBT-I. The American Academy of Sleep Medicine strongly recommends it for adults with chronic insomnia. It helps people work on the habits and thought patterns that can keep sleep trouble going.

There’s something lovely about ending the day with a warm mug and a little quiet. If chamomile makes that moment more inviting, enjoy it. And if the nights are still hard, give yourself the same patience you’d give a friend who’s worn out. You deserve help with the sleep you’re losing, and you can start by telling someone what your nights have really been like.
