Yes, you can mix chamomile and green tea, and the combination works well both in flavor and function. Chamomile’s mild, floral sweetness balances the grassy, slightly vegetal taste of green tea, and the two share some overlapping health benefits that may complement each other. The main thing to get right is the brewing temperature, since the two teas have different ideal ranges.
Why the Blend Works
Chamomile is naturally caffeine-free, so blending it with green tea dilutes the caffeine content of your cup. A standard 8-ounce serving of green tea contains roughly 24 to 39 milligrams of caffeine. If you use a 50/50 blend by weight, you’re cutting that to somewhere around 12 to 20 milligrams per cup, which is less than a quarter of what you’d get from coffee. That makes a chamomile-green tea blend a reasonable option for late afternoon drinking or for people who are sensitive to caffeine but still want a small lift.
Flavor-wise, chamomile’s honey-like, apple-tinged notes soften the bitterness that green tea can develop, especially if it’s slightly over-brewed. The combination tastes clean and light without either ingredient overpowering the other.
How to Brew the Blend
This is where most people run into trouble. Green tea and chamomile technically prefer different water temperatures. Green tea brews best between 160 and 180°F (70 to 80°C), with the sweet spot around 170 to 175°F. Go much hotter and the tea turns bitter. Chamomile, meanwhile, is often recommended at near-boiling temperatures (200 to 212°F) to extract its essential oils fully. But delicate chamomile flowers can actually turn tart if the water is too hot.
The simplest solution: brew both together at around 170°F for 3 minutes. This temperature is gentle enough to avoid bitterness from the green tea while still pulling plenty of flavor and aroma from the chamomile. You won’t get quite as strong a chamomile extraction as you would at boiling, but the blend will taste balanced and smooth. If you want more chamomile intensity without raising the temperature, just increase the proportion of chamomile flowers in your mix.
A good starting point is a 1:1 ratio by weight, roughly 2 grams of each for a single cup. From there, adjust to taste. If you prefer a more floral, calming cup, go heavier on the chamomile (try 3:1 chamomile to green tea). If you want more of the green tea’s body and a bit more caffeine, flip that ratio.
Overlapping Benefits for Blood Sugar
One of the more interesting findings about this pairing involves how both teas affect sugar absorption in the gut. A study published in the British Journal of Nutrition found that chamomile and green tea both inhibit digestive enzymes involved in breaking down sugars, specifically the enzymes that release glucose from starches. Both teas also blocked the transport of glucose and fructose through key channels in the intestinal wall.
Chamomile had an additional effect that green tea didn’t: it also blocked a separate transport channel specifically responsible for fructose absorption. Green tea, on the other hand, directly inhibited an enzyme called sucrase that chamomile left untouched. In other words, the two teas target sugar metabolism through slightly different pathways, which means drinking them together could offer broader coverage than either one alone. The researchers noted that both teas showed potential for managing blood sugar spikes from high-sugar meals, particularly those containing high-fructose corn syrup.
This doesn’t mean the blend is a treatment for diabetes. But if you’re drinking tea with or after a meal, the combination may offer a mild advantage for blood sugar control compared to drinking just one or the other.
Safety Considerations
For most people, mixing these two teas is completely safe. The main caution applies to chamomile specifically: it contains coumarin-like compounds that could theoretically interact with blood-thinning medications like warfarin. Many hospital websites warn patients to stop drinking chamomile two weeks before surgery because of bleeding risk.
That said, the clinical evidence behind this warning is thin. It traces back largely to a single case report of a 70-year-old woman on warfarin who developed internal bleeding after drinking four to five cups of chamomile tea daily. Her blood-clotting levels were dangerously elevated, and researchers speculated the chamomile’s coumarin compounds may have amplified the warfarin’s effect. A more recent randomized trial in healthy volunteers found no significant changes in coagulation from chamomile intake alone, though the study didn’t test people already taking anticoagulants.
If you take blood thinners, it’s worth being cautious with chamomile in any form. For everyone else, a cup or two of this blend daily poses no known risks beyond the modest caffeine from the green tea component.
Loose Leaf vs. Tea Bags
You can make this blend with tea bags (one of each steeped together), but loose leaf gives you much more control over the ratio and produces better flavor. Whole chamomile flowers release their oils more evenly than the crushed dust found in most bagged chamomile teas, and loose-leaf green tea is less likely to turn bitter since the leaves have room to unfurl in the water. If you’re mixing in bulk, combine your desired ratio in a jar, shake it to distribute evenly, and scoop about 4 grams total per 8-ounce cup.
For green tea variety, a mild Japanese sencha or a Chinese dragonwell pairs naturally with chamomile’s sweetness. Stronger, smokier green teas like gunpowder can overwhelm the chamomile, so you’d want to use less of those in the blend.
