Chamomile tea has a mild, indirect effect on constipation — useful for some people, especially when the constipation is stress-related or accompanied by cramping, but not the right tool for genuine slow-transit constipation. Understanding why it works the way it does helps you decide whether it fits your situation.
Chamomile is one piece of a bigger picture — caffeine, tannins, and hydration all shape how tea affects your gut. Our guide to whether tea causes constipation covers how the different tea types compare.
Chamomile is one of the most-recommended teas for digestion in general, and that broad recommendation has spilled over into constipation-specific advice. The reality is more nuanced than “drink chamomile and your constipation will resolve.”
How Chamomile Tea Affects the Gut
Chamomile contains several active compounds — apigenin, bisabolol, chamazulene, and matricin — that work primarily as antispasmodics and anti-inflammatory agents. Apigenin is the most-studied of these. It binds to GABA receptors in both the brain (producing the calming effect chamomile is known for) and the smooth muscles of the gut, where it relaxes muscle tension.
For digestion, this matters in three ways:
Reduced gut spasm. If your constipation involves cramping, urgency without productive output, or the sensation of your colon “fighting itself,” chamomile’s antispasmodic effect can ease that tension and let normal peristalsis resume.
Reduced inflammation. Low-grade gut inflammation slows motility. Chamomile’s anti-inflammatory action — well-documented in studies on functional dyspepsia — gradually improves the gut environment over days to weeks of regular use.
Stress and nervous-system effects. Constipation has a strong stress component for many people. The same GABA-mediated calming effect that helps people sleep also reduces the sympathetic nervous system activation that suppresses bowel movement. This is probably chamomile’s most useful function for constipation.
When Chamomile Tea Works for Constipation
Chamomile is most effective when one or more of these factors are involved:
Stress-driven constipation. Travel constipation, deadline weeks, post-surgery, or any period of acute stress where your gut has gone quiet. Chamomile’s nervous-system effect addresses the root cause directly.
IBS-related constipation. Especially the alternating type with cramping. The antispasmodic action on intestinal smooth muscle is a real benefit here. A 2014 review in Phytotherapy Research found chamomile reduced symptoms across multiple gastrointestinal disorders, with the strongest evidence for IBS and functional dyspepsia.
Constipation with bloating or gas. Chamomile is a mild carminative — it helps release trapped gas and reduces the bloated, distended feeling that can interfere with productive bowel movements.
Bedtime use. The relaxation effect supports sleep, and uninterrupted sleep itself improves bowel function. Chamomile before bed is a gentle two-for-one for stressed, sleep-deprived people whose digestion has slowed in response.
When Chamomile Doesn’t Help
If your constipation is purely mechanical — slow transit from low fiber, dehydration, or sluggish gut motility — chamomile won’t do much. There’s no laxative compound in chamomile, no caffeine for stimulation, no anthraquinones like senna. Drinking three cups won’t trigger a bowel movement the way a stimulant laxative tea would.
Specifically, chamomile is the wrong tool for:
Constipation from opioid medications, iron supplements, or other constipating drugs. Constipation from low fiber and low water intake. Chronic constipation lasting weeks. Severe acute constipation where you haven’t moved your bowels in 4+ days.
For those situations, you need either a more direct laxative approach (dandelion, ginger, or short-term senna) or attention to the underlying cause.
How to Brew Chamomile for Constipation
For maximum gut benefit, brew chamomile stronger and longer than you would for purely flavor:
Use 2–3 grams of dried chamomile flowers (about 2 teabags or 2 heaping teaspoons of loose flowers). Steep in 8 oz of just-below-boiling water for 8–10 minutes, covered to prevent volatile oil loss. The longer steep extracts more apigenin and other active compounds at the cost of slightly more bitter flavor — for digestive use, that tradeoff is worth it.
Drink 2–3 cups daily, with one specifically before bed. The bedtime cup compounds the gut benefits with sleep support.
Combining Chamomile With Other Approaches
Chamomile works best as part of a broader strategy rather than alone:
+ Ginger tea for motility. Ginger drives motility while chamomile reduces tension. Drink them at separate times — ginger morning, chamomile evening.
+ Adequate fiber and water. No tea works without these basics. Aim for 25 g fiber daily and 60+ oz water.
+ Walking after meals. Light movement triggers the gastrocolic reflex and helps motility. Combined with chamomile’s relaxation effect, this is unusually effective for stress-related constipation.
+ Magnesium. Magnesium glycinate or citrate at bedtime adds osmotic mild laxative effect that pairs well with chamomile’s relaxation. This combination helps many people more than either alone.
Chamomile vs. Other Teas for Constipation
Compared to other constipation tea options:
vs. Dandelion root: Dandelion is a more direct laxative; chamomile addresses the stress and tension that often drive constipation. Use dandelion for genuine slow transit, chamomile for stress-related slowdown.
vs. Peppermint: Peppermint is more stimulating to the gut; chamomile is more calming. For IBS-C with significant pain, peppermint usually does more. For IBS-C with anxiety, chamomile usually does more.
vs. Ginger: Ginger drives motility from the top down (gastric emptying); chamomile relaxes the gut from the inside. Different mechanisms. Often combined for best effect.
vs. Senna: Different category entirely. Senna is a stimulant laxative for occasional use; chamomile is a daily-safe support tea. Don’t substitute one for the other.
Side Effects and Cautions
Chamomile is one of the safest teas for daily use, but a few cautions apply:
Allergy. If you’re allergic to ragweed, daisies, marigolds, or chrysanthemums (the Asteraceae family), you may react to chamomile. Reactions range from mild oral irritation to anaphylaxis in severe cases.
Pregnancy. Most evidence suggests chamomile is safe in moderate amounts during pregnancy, but heavy use has been associated with uterine contraction in some studies. Limit to 1–2 cups daily during pregnancy, and check with your provider if you have a history of preterm labor.
Blood thinners. Chamomile has mild anticoagulant properties. If you’re on warfarin or similar medications, talk to your doctor before drinking large amounts.
Sedation. Chamomile has mild sedating effects. Don’t pair high doses with sleep medications, alcohol, or before activities requiring alertness.

The Bottom Line
Chamomile tea helps constipation when the cause involves stress, gut tension, IBS-style cramping, or accompanying bloating — through antispasmodic, anti-inflammatory, and nervous-system effects rather than direct laxative action. For mechanical constipation from low fiber or slow transit, it’s not the right tool.
For daily gut health, 2–3 cups of well-steeped chamomile (especially one before bed) is a low-risk, broadly beneficial addition to your routine. Combine with ginger for motility, dandelion for true laxative effect, or magnesium for nighttime support depending on what your specific situation needs.
Frequently Asked Questions
How many cups of chamomile tea should I drink for constipation?
2–3 cups daily of well-steeped chamomile (8–10 minute steep, 2 teabags or 2 tsp dried flowers per cup) is the standard therapeutic range. One cup before bed is particularly useful. Above 4 cups daily, the sedation effect can become noticeable.
How fast does chamomile tea work for constipation?
Chamomile isn’t a fast-acting laxative. For stress-related constipation, you may notice improvement within 24–48 hours of consistent use. For IBS-related symptoms, full benefits typically appear after 1–2 weeks of daily intake.
Can chamomile tea cause constipation?
Rarely, but possible. The muscle-relaxing effect can over-relax intestinal muscles in people who are already constipated due to weak motility. If chamomile seems to make your constipation worse rather than better, switch to ginger or dandelion tea instead.
Is chamomile tea safe for daily use?
Yes, for most adults. It’s one of the most well-tolerated teas in regular use. Exceptions: allergy to Asteraceae plants, late-stage pregnancy, blood-thinner medications. For everyone else, daily chamomile is safe and beneficial.
