Top Herbal Tea Flavors: Celestial Seasonings and Yogi

Celestial Bengal Spice (a herbal blend) contains 0 mg of caffeine per 240 ml cup (herbal tea, caffeine-free).

• 0 mg — Celestial Bengal Spice and most Celestial/Yogi herbal-only blends are caffeine-free per 240 ml cup.
• 47 mg — A 240 ml cup of black tea typically contains ~47 mg of caffeine (use this to compare strength).
• 70 mg — Matcha (1 tsp, 240 ml) is a concentrated tea with ~70 mg caffeine per serving.
• 96 mg — Standard 240 ml drip coffee contains ~96 mg; use this value for decay math and sleep timing examples.
• 400 mg/day — FDA's recommended upper limit for healthy adults; aim lower in pregnancy (~200 mg/day) and for adolescents the AAP discourages regular caffeine use.

Why Bengal Spice is caffeine-free and what that means

Celestial Bengal Spice is formulated as an herbal, spice-forward tisane rather than a Camellia sinensis infusion. That means its base is dried spices and herbs — not black or green tea — so caffeine is effectively zero for a standard 240 ml steep (dataset value: 0 mg). The lack of caffeine makes Bengal Spice a late-evening choice when you want warming aromatics without alertness.

Flavor groups: Celestial Seasonings fruit zingers

Fruit Zinger-style blends center hibiscus, orange peel and apple for bright, tart-sweet cups. Celestial Seasonings' fruit lineup emphasizes lively acidity and aroma rather than tannic bitterness — these are naturally caffeine-free when they contain only fruit and herbs. Steep 5–7 minutes for full flavor; cool quickly for iced variations.

Spice and comfort blends: Bengal Spice and kin

Bengal Spice and similar blends layer cinnamon, cardamom, cloves and ginger. The result is chai-like warmth without tea-caffeine. These blends are designed for aroma and digestive comfort; they can be mixed with milk or a plant milk for a caffeine-free 'chai' experience. If a blend includes black tea, expect caffeine near black tea levels (≈47 mg per 240 ml).

Herbal wellness teas (Yogi examples) and what to expect

Yogi markets many functional herbal blends — Turmeric Ginger, Honey Lavender, and so on — that are typically caffeine-free when made from herbs and roots. Yogi also produces blends containing black or green tea: those will carry caffeine roughly in the range of green tea (~28 mg/240 ml) to black tea (~47–50 mg/240 ml). Check packaging and use the USDA FoodData Central or product label for exact numbers.

Comparing Celestial Seasonings and Yogi: flavor, caffeine, and use cases

Both brands offer large herbal portfolios. Practical differences:

• Focus: Celestial leans fruit- and spice-forward bagged blends; Yogi emphasizes 'functional' blends with Ayurvedic-inspired herbs.
• Caffeine: Herbal-specific offerings from both are 0 mg per 240 ml. If a blend contains black/green tea, use black tea (≈47 mg) or green tea (≈28 mg) as benchmarks.
• Preparation: Both perform well as steeped hot tea, iced, or in milk-based preparations; stronger steeps extract more flavor but not caffeine from true herbals.

How brewing, format and ingredients affect caffeine

For true herbals, steep time and temperature affect flavor and extraction of volatile oils, not caffeine. For blends that include Camellia sinensis leaves, caffeine per 240 ml depends on leaf type and method: dataset comparisons show drip coffee 96 mg/240 ml, pour-over 145 mg/240 ml, French press 107 mg/240 ml, and black tea ~47 mg/240 ml. Processing (instant, cold brew) and concentration create larger spreads — cold brew can reach 200 mg per 240 ml in concentrated servings.

Timing, half-life and sleep: concrete decay math

Caffeine follows first-order kinetics with a population-average half-life of ~5.7 hours (sources: FDA, Mayo Clinic summaries). That means roughly 69% remains after 3 h, 48% after 6 h, 33% after 9 h and 23% after 12 h. Use the table below to estimate how much caffeine remains from a 96 mg drip coffee.

Practical takeaway: a 96 mg morning cup leaves measurable caffeine in the bloodstream well into the afternoon and early evening for many people. For sensitive sleepers, avoid caffeine within 6–8 hours of bedtime.

Health, safety and tracking

Agency guidance: the FDA cites 400 mg/day as a reasonable upper limit for healthy adults; pregnant people are commonly advised to limit intake to ~200 mg/day (varies by guideline). The American Academy of Pediatrics discourages caffeine for young adolescents because of sleep and developmental concerns. Herbal blends like Bengal Spice let you enjoy warming flavors without counting toward these limits.

If you track multiple sources (tea, coffee, energy drinks, pills), a tracker like CoffeeLog helps total daily intake and timing so you can correlate caffeine with sleep and symptoms. For medical questions about pregnancy, anxiety, heart conditions or suspected overdose, consult a clinician immediately — this page is informational, not medical advice.

Can I blend Bengal Spice with black tea and how much caffeine will the cup have?

Yes — you can mix Bengal Spice with black tea and the caffeine in the finished cup scales directly with how much Camellia sinensis you include, so a half-and-half cup made from 120 ml black tea plus 120 ml Bengal Spice contains about 23.5 mg of caffeine. The dataset lists black tea at 47 mg per 240 ml, so 120 ml (half of 240 ml) supplies 47 × 120/240 = 23.5 mg (the dataset).

Blend ratio is the fraction of each liquid in the final cup measured by volume. Use that fraction to prorate dataset values: for any blend, caffeine (mg) = volume fraction of caffeinated component × its dataset mg per 240 ml × (actual cup volume/240 ml). For example, a 360 ml cup made of two-thirds Bengal Spice (0 mg) and one-third black tea gives 47 × (120/240) = 23.5 mg, and the Bengal Spice portion contributes 0 mg (the dataset).

Practical caveat: if you steep an actual commercial tea bag that contains both herbals and real tea leaves, treat the labeled blend as a caffeinated product and use a black- or green-tea benchmark — see our guide on black tea caffeine and compare in the caffeine comparison tool.

How much caffeine do I avoid if I replace my morning drip coffee with Bengal Spice?

Replacing one 240 ml drip coffee (96 mg per the dataset) with a 240 ml cup of Bengal Spice (0 mg per the dataset) avoids 96 mg of caffeine that day. Over a five-day workweek that substitution avoids 96 × 5 = 480 mg of caffeine (the dataset).

Avoided dose is the caffeine milligram difference between two beverage choices. If you currently drink two 240 ml drip coffees (2 × 96 mg) and swap both for Bengal Spice, you remove 192 mg per day; compare that to the FDA's 400 mg/day guidance (the FDA) when assessing total intake.

If you want to quantify the timing impact of the avoided cup, use our caffeine half-life calculator to see how much caffeine would have remained later in the day from a 96 mg dose using the 5.7-hour half-life model discussed below.

Will drinking Bengal Spice help with caffeine withdrawal or tolerance?

Switching habitual caffeinated drinks to Bengal Spice removes the daily caffeine stimulus and so removes the driver of tolerance; many people experience withdrawal symptoms when they cut caffeine abruptly. Withdrawal is a predictable physiological syndrome that includes headache, fatigue and irritability after stopping or reducing regular caffeine intake.

Our caffeine withdrawal guide summarizes typical timelines and symptom management strategies and is the reference we use for expectations on onset and peak. Practical approach: replace a morning caffeinated beverage with Bengal Spice while keeping one lower-dose option (for example, a 240 ml latte at 68 mg per the dataset) to taper rather than quit cold if you want to reduce withdrawal risk.

For logging and spotting symptom patterns, put the swap into a tracker or use CoffeeLog once to timestamp doses and symptom entries, then compare days with and without caffeine in our calculator.

How does 'herbal' labeling differ from 'decaf' or 'naturally caffeine-free' on a package?

An "herbal" label means the infusion is made from herbs, fruits or spices rather than Camellia sinensis, and such herbal teas register 0 mg of caffeine per 240 ml in the dataset. The dataset marks "Herbal tea (caffeine-free)" at 0 mg per 240 ml.

Decaffeinated (decaf) is processed tea or coffee from which most caffeine has been removed, not a claim of absolute zero. Decaffeinated coffee in the dataset still contains about 3 mg per 240 ml (the dataset), so reading labels matters if you need truly zero caffeine for sleep or medical reasons.

If a product label reads "naturally caffeine-free" or simply "herbal," you can treat it as 0 mg per the dataset; if the product is labeled "decaf" check the package and, when in doubt, consult USDA FoodData Central or the manufacturer's nutrition facts for exact mg values before combining with a caffeinated beverage.

Can Bengal Spice replace an evening energy drink and how long would that cut lower evening caffeine?

Yes — swapping a 250 ml Red Bull (80 mg per the dataset) for a 240 ml Bengal Spice (0 mg) removes 80 mg of evening caffeine exposure immediately. The dataset lists Red Bull (250 ml) at 80 mg, so that 80 mg is eliminated the moment you stop drinking the energy drink.

First-order elimination is a process where the drug amount declines by a constant proportion per unit time; for caffeine we use a population-average half-life of 5.7 hours (342 minutes) as a working model (the Mayo Clinic). Using that model, 6 hours after an 80 mg evening dose about 80 × 0.5^(6/5.7) ≈ 38.4 mg remains (half-life math using 5.7 h). The Mayo Clinic provides the half-life summary we apply in this calculation (the Mayo Clinic).

Practical takeaway: replacing a 250 ml Red Bull with Bengal Spice removes an immediate 80 mg dose and, using the 5.7-hour half-life model, prevents about 38 mg still being present six hours later — useful when timing the last stimulant before bed and when using our last-cup-before-bed tool.

Bottom line

Celestial Bengal Spice is an herbal blend and contains 0 mg of caffeine per 240 ml (the dataset). That zero-mg profile makes Bengal Spice a direct substitute for any caffeinated drink when your goal is to remove caffeine from your day: replacing one 240 ml drip coffee (96 mg per the dataset) with Bengal Spice avoids 96 mg immediately, and replacing a 250 ml Red Bull (80 mg per the dataset) avoids 80 mg immediately.

Caffeine follows first-order elimination with a population-average half-life of 5.7 hours (342 minutes), so whatever caffeine you avoid by choosing Bengal Spice instead would otherwise decline by roughly half every 5.7 hours (the Mayo Clinic). Put another way, a 96 mg morning drip coffee would leave about 46.1 mg after 6 hours (96 × 0.5^(6/5.7) ≈ 46.1 mg) and a 250 ml Red Bull (80 mg) would leave about 38.4 mg after 6 hours (80 × 0.5^(6/5.7) ≈ 38.4 mg) using the half-life model.

Use the FDA's 400 mg/day benchmark when measuring overall risk and the EFSA 2015 pregnancy guidance of ~200 mg/day if you are pregnant (the FDA; EFSA 2015). For practical tools, compare drink values in our caffeine comparison, run timing math in our half-life calculator, and pick the last acceptable cup with last cup before bed to match your sleep goals.
