What is a tisane?
A tisane is an herbal infusion from anything other than the tea plant, so 'herbal tea' isn't technically tea. Here's the difference from real tea, and why caffeine varies.
A tisane is an herbal infusion made from anything other than the tea plant — herbs, spices, flowers, roots, or fruit. That means “herbal tea” isn't technically tea at all. True teas (green, black, oolong, white, pu-erh) all come from Camellia sinensis and contain caffeine; tisanes like rooibos, chamomile, or peppermint are usually caffeine-free.
True tea vs tisane
| Property | True tea | Tisane (herbal “tea”) |
|---|---|---|
| Made from | Camellia sinensis leaves | Herbs, spices, flowers, roots, fruit |
| Caffeine | Yes (varies by type) | Usually none (a few exceptions) |
| Examples | Green, black, oolong, white, pu-erh | Rooibos, chamomile, peppermint, ginger, hibiscus |
| Brewing | Shorter, temperature matters | Often longer steeps, near-boiling |
Why the distinction matters
Calling everything “tea” is common and harmless in daily speech, but the label tells you two useful things. First, caffeine: a true tea will have some; a pure herbal tisane usually won't — handy if you're avoiding caffeine at night. Second, brewing: many tisanes are more forgiving and can steep longer and hotter without turning bitter, while delicate green teas can't.
Common caffeine-free tisanes
Rooibos, chamomile, peppermint, ginger, hibiscus, and lemongrass are all tisanes. Rooibos is a popular one because it's naturally caffeine-free and low in the tannins that make some teas astringent — more in is rooibos caffeine-free and rooibos.
What about spiced or blended “teas”?
It depends on the base. A masala chai is built on black tea, so it's a true tea with a caffeine content, spices and all. A caffeine-free “herbal chai” built on rooibos is a tisane. If caffeine matters to you, check what the base actually is — see what is masala chai and black tea.
Frequently asked questions
What is a tisane?
A tisane is an herbal infusion made from plants other than the tea plant — herbs, spices, flowers, roots, or fruit. Chamomile, peppermint, rooibos, and ginger 'teas' are all tisanes.
Is herbal tea real tea?
Technically no. Real tea comes from Camellia sinensis (green, black, oolong, white, pu-erh). Herbal 'teas' are tisanes — infusions of other plants — even though everyone calls them tea.
Do tisanes have caffeine?
Most don't. Pure herbal tisanes like chamomile, peppermint, and rooibos are naturally caffeine-free. A few exceptions (like yerba mate) contain caffeine, so check if it matters to you.
Is chai a tea or a tisane?
It depends on the base. Masala chai is built on black tea, so it's a true, caffeinated tea. A caffeine-free 'herbal chai' made on a rooibos base is a tisane.
