chamomile herbal tea vs brewed oolong tea: the numbers

Sources: chamomile herbal tea's figure is verified in our chamomile herbal tea caffeine guide against USDA / naturally caffeine-free herbal (source); brewed oolong tea's figure is verified in our brewed oolong tea guide against USDA FoodData Central (source).

The concentration gap is the striking part: brewed oolong tea packs roughly 462 times the caffeine per ounce. Sipping speed matters at that density; a 8 oz cup finished in minutes hits differently than the same milligrams spread over a slow cup.

Which one should you pick?

Pick chamomile herbal tea when you want the lighter dose or a slower ramp, and brewed oolong tea when you actually need the bigger hit and know your tolerance. If you are stacking either with other caffeinated drinks through the day, run the math against the 400mg reference rather than guessing.

For context, the FDA cites 400mg of caffeine a day as an amount generally not associated with negative effects in healthy adults. Tolerance and health vary, so treat these numbers as information, not advice.
