Plain herbal teas are naturally gluten-free — botanical infusions, no grain.
Yes. Herbal teas (tisanes) are infusions of herbs, flowers, roots, and fruits — chamomile, peppermint, rooibos, ginger, hibiscus — with no wheat, barley, rye, or oats in their plain form. The Republic of Tea maintains a dedicated gluten-free tea category. Two things to watch: flavored/dessert blends that add barley or malt, and barley-based “teas” (roasted barley tea / mugicha), which are made from barley and are NOT gluten-free.
Plain herbal tea is gluten-free. It’s just botanicals steeped in water — flowers, leaves, roots, fruit. There’s no grain in a chamomile or peppermint tea. The only real gluten traps are flavored dessert blends that sneak in barley malt, and the genuinely confusing case of “barley tea,” which is literally made from barley.
What’s in Herbal Tea
Herbal teas (tisanes) are infusions of herbs, flowers, roots, fruits, and spices — chamomile, peppermint, rooibos, ginger, hibiscus, lemongrass, and so on. They contain no true tea leaf. Per FDA labeling rules, the gluten-containing grains are wheat, barley, rye, and their hybrids — none of these botanicals is on that list. The Republic of Tea maintains a dedicated gluten-free tea category and states its pure teas are gluten-free.

Frequently Asked Questions
Is herbal tea gluten-free?
Yes. Plain herbal teas are infusions of herbs, flowers, roots, and fruits — chamomile, peppermint, rooibos, ginger, hibiscus — with no wheat, barley, rye, or oats. The Republic of Tea maintains a dedicated gluten-free tea category for its pure teas.
Is barley tea gluten-free?
No. Roasted barley tea (mugicha and similar grain teas) is made from barley, which is a gluten-containing grain. Despite being called “tea,” barley tea is not gluten-free and is not safe for celiac disease.
Is chamomile or peppermint tea gluten-free?
Yes. Single-botanical herbal teas like chamomile, peppermint, ginger, and hibiscus are naturally gluten-free. They contain only the dried herb or flower and no grain.
Is rooibos tea gluten-free?
Yes. Rooibos (red bush) and honeybush are South African botanicals, not grains, and are naturally gluten-free. Flavored rooibos blends should still be checked for added barley or malt.
Are flavored herbal tea blends gluten-free?
Usually, but verify. Dessert-style or “toasted/cookie” herbal blends can add barley malt or grain-derived flavorings. The botanical base is gluten-free; the risk is the added ingredients, so read the list.
Can people with celiac disease drink herbal tea?
Yes. Plain herbal teas are naturally gluten-free and safe for celiac disease. Avoid barley-based “teas” and check flavored blends, where added barley or malt — not the herbs — would be the gluten source.
