Quick Answer: No, chamomile tea contains zero caffeine. It is made from the dried flowers of the Matricaria chamomilla plant, which naturally produces no caffeine at all. This makes it one of the safest herbal teas to drink at night and a reliable alternative to caffeinated beverages for people trying to improve sleep.

People switching away from caffeinated beverages in the evening often reach for chamomile tea, but they are not always sure whether it is truly caffeine-free. The answer is an unambiguous yes -- chamomile is completely caffeine-free -- and understanding why this matters for sleep is worth a few minutes of your time.
Why Chamomile Has No Caffeine
Caffeine is a xanthine alkaloid produced by certain plants -- primarily Camellia sinensis (the tea plant), Coffea arabica and robusta (coffee), Theobroma cacao (cacao), and Paullinia cupana (guarana). It serves as a natural pesticide in these plants, deterring insects from consuming their seeds and leaves.
Chamomile (Matricaria chamomilla or Roman chamomile, Chamaemelum nobile) belongs to the Asteraceae family and does not produce caffeine at any growth stage. The dried flowers used to make chamomile tea contain apigenin, bisabolol, chamazulene, and various flavonoids -- but no xanthine alkaloids of any kind. There is no processing step that adds caffeine, and no variant of chamomile that contains it.
True Herbal Teas vs. "Tea" from Camellia Sinensis
A useful distinction: "true teas" (green, black, white, oolong, pu-erh) all come from Camellia sinensis and all contain caffeine (50 to 200 mg per cup depending on preparation). Herbal teas -- also called tisanes -- are infusions of herbs, flowers, fruits, and spices that are not from the Camellia sinensis plant. Chamomile is a herbal tea (tisane) and is naturally caffeine-free.
Why Caffeine-Free Matters for Sleep
Caffeine blocks adenosine receptors in the brain. Adenosine is a neurotransmitter that accumulates throughout the day and signals increasing sleepiness -- the longer you are awake, the more adenosine builds up, and the more strongly you feel the drive to sleep. Caffeine blocks adenosine from binding to its receptors, temporarily suppressing this sleep drive signal.
The problem with evening caffeine consumption is persistence. Caffeine has a half-life of approximately five to seven hours in most adults. This means that a coffee drunk at 3pm still has half its caffeine present in your bloodstream at 8 to 10pm -- directly interfering with adenosine signalling at the very time your body is trying to prepare for sleep.
Drinking a caffeinated beverage in the evening -- even one you think of as "light" like green tea -- can meaningfully delay sleep onset, reduce total sleep time, and reduce the proportion of slow-wave sleep you obtain. Replacing it with caffeine-free chamomile tea avoids these problems entirely.
Caffeine Half-Life and Evening Cutoff
Sleep researchers and the American Academy of Sleep Medicine generally recommend stopping caffeine consumption at least six hours before bed, though some experts recommend eight to ten hours for people who are caffeine-sensitive. Here is what that looks like in practice:
| Target Bedtime | 6-Hour Cutoff | 8-Hour Cutoff |
|---|---|---|
| 10:00 pm | 4:00 pm | 2:00 pm |
| 11:00 pm | 5:00 pm | 3:00 pm |
| Midnight | 6:00 pm | 4:00 pm |
If you enjoy a warm beverage in the evening -- a habit with genuine psychological and social benefits -- chamomile tea is an excellent solution. It provides a comforting ritual, zero caffeine impact on sleep architecture, and the added benefit of apigenin's mild sedative properties.
Dorothy on Evening Beverage Habits
"One of the most common sleep mistakes we hear about at Mattress Miracle is underestimating how late people can comfortably drink caffeine. People are surprised when they learn that a 4pm coffee is still significantly active at 9pm. Switching to chamomile in the afternoon or evening is one of the simplest, most impactful sleep changes you can make."

Watch Out for Chamomile Blends
Pure chamomile tea is always caffeine-free, but blended "chamomile" teas on supermarket shelves sometimes contain other ingredients that may include caffeine. Read labels carefully:
- Chamomile green tea blends: These contain actual green tea (Camellia sinensis) alongside chamomile. They have caffeine -- typically 20 to 45 mg per cup, lower than pure green tea but not zero.
- Chamomile matcha blends: Matcha is ground green tea and contains significant caffeine (40 to 70 mg per cup).
- Chamomile white tea blends: White tea from Camellia sinensis contains caffeine, typically 15 to 30 mg per cup.
- Pure chamomile herbal tea: Always caffeine-free. Look for single-ingredient labels listing only Matricaria chamomilla or "chamomile flowers."
Other Caffeine-Free Teas for Sleep
If you want variety in your evening tea rotation, several other herbal teas are also naturally caffeine-free and offer sleep-supporting properties:
- Valerian root tea: Contains valerenic acid, which modulates GABA receptors. Stronger sedative evidence than chamomile, with a more pungent flavour.
- Lemon balm tea: From Melissa officinalis; reduces anxiety and may shorten sleep onset time. Often blended with chamomile.
- Passionflower tea: Contains chrysin and other flavonoids that interact with GABA-A receptors; some clinical evidence for sleep quality improvement.
- Lavender tea: Linalool and linalyl acetate in lavender have sedative properties; also available as an inhalation (aromatherapy).
- Peppermint tea: Caffeine-free; not specifically sedating, but relaxing muscles and easing digestion may help with comfort before bed.

Is decaffeinated chamomile tea a thing?
No, because chamomile has no caffeine to remove. You will never see "decaffeinated chamomile" because the decaffeination process is only relevant for true teas from Camellia sinensis. All chamomile tea is naturally caffeine-free.
Can I drink chamomile tea if I am sensitive to caffeine?
Yes. Chamomile is an excellent choice for people who are caffeine-sensitive or who have been advised to reduce their caffeine intake. There is no caffeine of any kind in pure chamomile tea.
Does chamomile tea keep you awake?
No -- quite the opposite. Chamomile is mildly sedating due to its apigenin content, which acts on GABA receptors. It is one of the herbs most commonly recommended for improving sleep.
How much caffeine is in chamomile tea?
Zero milligrams. Chamomile is entirely caffeine-free. If a product labelled "chamomile tea" contains caffeine, it contains other ingredients (like green tea or white tea) in addition to or instead of pure chamomile.
