<<Disclaimer: Verify this information before applying it to your situation.>> Hi! I e-mailed Celestial Seasoning's regarding the gluten-free status of their teas and this was the reply: "Persons that have reactions to gluten should avoid consuming any wheat, barley, oats or rye. Some Celestial Seasonings' products contain roasted barley and/or roasted barley malt. These ingredients are always listed on the label when present. Another potential issue concerning some gluten-sensitive individuals may be natural flavors. Some natural flavors are extracted using grain alcohol derived from corn. According to our reference sources, this should not be an area of concern and should not interfere with a gluten-free regimen. If you have additional questions or would like further information, please call us toll-free at 1-800-351-8175." Sincerely, Jeanean Davis Edison, New Jersey
