Chamomile is used primarily as a mild sedative and digestive aid, but its applications extend to anxiety relief, menstrual pain, blood sugar management, and skin care. It’s one of the most widely consumed herbal teas in the world, and unlike many folk remedies, several of its traditional uses have at least preliminary clinical support.
Sleep and Falling Asleep Faster
The most popular reason people reach for chamomile tea is to wind down before bed. In a placebo-controlled pilot study of people with chronic insomnia, a standardized chamomile extract cut the time it took to fall asleep by about 16 minutes over four weeks. Participants went from an average of 50 minutes to fall asleep down to about 34 minutes. They also woke up fewer times during the night, dropping from an average of 2.2 awakenings to 1.4.
The effect is real but modest. Measures of overall sleep quality and total time spent asleep showed only small improvements compared to placebo. Chamomile won’t knock you out like a prescription sleep aid. Think of it more as something that takes the edge off restlessness, helping you transition into sleep a bit more smoothly. The calming effect appears to come partly from a plant compound called apigenin, which reduces excitatory brain activity rather than directly sedating you the way a sleeping pill would.
Anxiety and Everyday Stress
Chamomile has been tested specifically in people diagnosed with generalized anxiety disorder. A randomized, double-blind trial found that chamomile extract produced a significantly greater reduction in anxiety scores compared to placebo. This wasn’t chamomile tea but a concentrated extract taken in capsule form, so the dose was higher than what you’d get from a cup of tea.
Still, plenty of people report that the ritual of drinking a warm cup of chamomile tea itself helps them feel calmer. Whether that’s the pharmacology of the plant, the comfort of a warm drink, or both working together is hard to untangle. If you’re dealing with mild, everyday anxiety, chamomile tea is a low-risk option. For clinical anxiety disorders, it’s not a substitute for evidence-based treatment, but some people find it a helpful complement.
Digestive Comfort and Cramping
Chamomile has been used for centuries to settle upset stomachs, and lab research confirms a plausible mechanism. The flavonoids in chamomile directly relax smooth muscle tissue in the gut. This is the type of involuntary muscle that lines your intestines and can spasm during indigestion, bloating, or irritable bowel episodes. The relaxant effect is prolonged rather than fleeting, which may explain why chamomile tea after a meal seems to ease discomfort for a while.
This makes chamomile most useful for cramping, gas, and the kind of general stomach upset that doesn’t have a serious underlying cause. It won’t treat acid reflux or inflammatory bowel disease, but for garden-variety digestive discomfort, there’s a reasonable biological basis for why it helps.
Menstrual Pain Relief
Several clinical trials have looked at chamomile for period cramps, and a systematic review found consistent evidence that it reduces pain intensity. In one protocol, women took chamomile capsules every eight hours starting 48 hours before menstruation and continuing until 24 hours after. Pain scores dropped significantly after two menstrual cycles of use. Another trial saw similar results when capsules were taken during the first three days of menstruation over two cycles.
The pattern across studies suggests chamomile works best when used consistently over multiple cycles rather than as a one-time remedy. This aligns with how its anti-inflammatory and muscle-relaxant properties work: they build a mild but cumulative effect rather than delivering immediate, dramatic relief.
Blood Sugar and Cholesterol
For people with type 2 diabetes, chamomile tea may offer a small metabolic benefit. A clinical trial comparing chamomile tea drinkers to a control group found that regular consumption significantly decreased HbA1c (a marker of long-term blood sugar control), fasting insulin levels, and insulin resistance. It also improved cholesterol numbers, lowering total cholesterol, triglycerides, and LDL cholesterol.
These are meaningful markers, but the reductions were modest. Chamomile tea won’t replace diabetes medication or lifestyle changes. It’s better understood as one small, pleasant habit that nudges metabolic markers in the right direction, particularly for someone already managing their condition through diet and exercise.
Skin and Wound Healing
Chamomile shows up in countless skincare products, and it does have mild anti-inflammatory properties when applied topically. However, the clinical evidence here is weaker than you might expect. A rigorous trial comparing chamomile-based cream to low-dose hydrocortisone cream for moderate eczema found that the hydrocortisone was clearly superior. The chamomile cream performed no better than the base cream without any active ingredient.
That doesn’t mean chamomile is useless on skin. It may soothe minor irritation, sunburn, or mild redness. But for conditions like eczema or dermatitis, it’s not a reliable alternative to standard treatments. If you enjoy chamomile in your skincare routine, there’s no harm in it, but don’t count on it for anything beyond mild, temporary soothing.
How to Get the Most From Chamomile Tea
Brewing method matters. Research on polyphenol extraction from herbal teabags found that about seven minutes of steeping in boiled water is the sweet spot for pulling the most beneficial compounds out of chamomile. Shorter steeping times leave a significant portion of the flavonoids behind in the bag. You don’t need to be precise, but if you’ve been dunking your teabag for two minutes and tossing it, you’re likely getting a fraction of the active compounds.
For sleep, drinking a cup 30 to 45 minutes before bed gives the mild sedative effects time to build. For digestive purposes, tea after a meal is the traditional approach and aligns with the smooth muscle relaxation timeline. Chamomile supplements in capsule form deliver a much higher dose than tea and are what most clinical trials have used, so if you’re looking for more pronounced effects, capsules are the more studied option.
Safety and Who Should Be Cautious
Chamomile is safe for most people at normal tea-drinking amounts. Allergic reactions are the primary concern, especially if you’re allergic to plants in the daisy family (ragweed, chrysanthemums, marigolds). Reactions range from mild skin irritation to, rarely, more serious responses.
The more significant caution involves blood-thinning medications like warfarin. Chamomile contains natural coumarin compounds that could theoretically amplify anticoagulant effects. At least one documented case involved a 70-year-old woman on warfarin who developed serious internal bleeding after using chamomile products (both tea and body lotion) to treat cold symptoms. While this is a single case report, it was significant enough that researchers recommend treating chamomile as a potential interaction risk for anyone on blood thinners. If you take warfarin or similar medications, this is worth discussing with your pharmacist before making chamomile a daily habit.
