# Is Herbal Tea Hydrating? Does Herbal Tea Have Caffeine? Yes. Brewed herbal tea is 99.7% water and counts toward your water intake in full. Chamomile, hibiscus and other herbal teas show no caffeine in USDA data. ## Numbers the app uses | Field | Value | | --- | --- | | Default serving | 240 ml (8.1 fl oz) | | Hydration factor | 1.00 | | Counts toward the daily goal | 240 ml per serving | | Calories | 1 kcal per 100 ml (2 kcal per serving) | ## Almost pure water USDA figures for brewed chamomile and for other brewed herbal teas show 99.7 g of water per 100 g, 1 kcal or less, and no caffeine. ([USDA FoodData Central](https://fdc.nal.usda.gov/food-details/174156/nutrients)) Hibiscus tea also shows 0 mg of caffeine. ([USDA FoodData Central](https://fdc.nal.usda.gov/food-details/171946/nutrients)) The Beverage Hydration Index trial tested black tea, hot and iced, and both were no different from still water. ([Maughan et al., 2016](https://pubmed.ncbi.nlm.nih.gov/26702122/)) Herbal tea was not tested, and it has no caffeine at all. WaterChamp counts it at a hydration factor of 1.00, the same as water. ## Which herbal drinks have caffeine Most herbal teas have no caffeine. The common exceptions: - Blends that include green or black tea leaves. The ingredients list says so. - Yerba mate, an infusion from a South American holly, which releases caffeine and related stimulants (methylxanthines) into the cup. ([Meinhart et al., 2010](https://pubmed.ncbi.nlm.nih.gov/20058928/)) It is logged as its own drink, with caffeine. Decaf tea is real tea with most of the caffeine removed, and the FDA notes that decaf teas still contain some. ([FDA](https://www.fda.gov/consumers/consumer-updates/spilling-beans-how-much-caffeine-too-much)) A cup of Decaf Tea counts as 2 mg. ## Herbal drinks you can log Herbal Infusion, Rooibos, Fruit Tea and Barley Tea all count at 0 mg of caffeine and a factor of 1.00. Turmeric Latte, made with milk, sits at 1.10. Since herbal tea has no caffeine, a late cup adds nothing to the bedtime figure in the [caffeine calculator](/tools/caffeine-cutoff/). ## Questions ### Does herbal tea count as water intake? Yes.
