The Story Behind Chamomile Herbal Tea: Why It's the Best Bedtime Brew

Chamomile is often known to be calming. That's true, but what are the actual reasons why, and a detail about the plant itself that most people buying chamomile tea have never been told. 

Not All Chamomile Is the Same Plant

Here's the detail that gets missed almost everywhere: "chamomile" isn't one single plant. German chamomile (Matricaria chamomilla, sometimes labelled M. recutita) and Roman chamomile (Chamaemelum nobile) are two genuinely different species, often sold under the same generic name with no distinction made on the label. Roman chamomile shows up far more often in essential oils and aromatherapy than in a teacup.

German chamomile is the one most commonly used in tea and the one most studied for its calming properties. It is also used to make our authentic Ceylon Chamomile herbal teas as well. 

The reason for this is that German chamomile has a short growing season. So, farmers in Sri Lanka can time the harvesting and avoid the monsoon rains in the country. But Roman chamomile has a long growing season, and this makes it impossible to save it from the rain.

It's worth checking which one you're actually buying. A pack that just says "chamomile" with no botanical name listed could be either, and if you've ever had a chamomile tea that tasted thin or oddly bitter compared to another, species difference is a genuine possible reason, not just a quality gap between brands.

Warmth, the Factor That Complements the Tea

Part of how your body signals it's ready for sleep is a drop in core temperature, and warming yourself up beforehand, then cooling down afterward, is thought to help trigger that process. 

It's the same principle behind why a warm bath before bed is a well-known sleep aid. The warmth causes blood vessels near the skin to dilate, which speeds up heat loss as you cool back down afterwards, nudging your body toward its natural pre-sleep temperature drop.

A warm drink works on a smaller scale, but the same idea applies. When you feel like “it’s switching you off” when drinking a chamomile tea, the warmth play a significant role. The ritual, and the simple act of sitting still with a hot drink for a few minutes before bed.

How to Judge Real Chamomile Tea Quality When You're Buying It

A few things worth checking, whichever brand you buy:

Whole flowers vs. dust and fannings. 

Chamomile's essential oils are concentrated in the flower head itself. Teas made from crushed petals or leftover plant dust lose much of that aroma and flavour before the bag is even sealed. You can smell the aroma of chamomile even in loose format or in pyramid tea bag format.

Colour. 

Good chamomile should look pale gold to light yellow-green, not dull brown. A browner colour usually means the flowers were harvested past their prime or stored too long before packing.

Aroma before brewing. 

Real chamomile should smell distinctly floral with a soft apple-like note, even dry, straight from the bag. If there's little to no scent before hot water touches it, there's unlikely to be much flavour once it's brewed either. The aroma compounds degrade over time, so a faint smell is often a sign of age rather than a mild variety.

Harvest timing. 

Chamomile flowers are typically picked at full bloom, when their essential oil content peaks; flowers picked too early or too late yield a noticeably flatter cup, regardless of species or growing region.

Ceyara's chamomile is grown in the cool highland climate of Haputale, Sri Lanka, using whole Matricaria chamomilla flower heads rather than crushed fillers. If you'd like to try a cup built on everything above, explore our Chamomile Herbal Tea.
