Pukka'a Advent Calendar features 24 carefully selected, organic herbal tea, fruit and green teas. Countdown to Christmas with a different tea every day! All Pukka organic herbal teas are free from gluten containing ingredients. However, we want to point out that Night Time and Relax tea bags contain oat straw flowering tops. Although the analytical tests undertaken on these teas show that gluten is absent, consumers who are extremely sensitive may want to check the suitability of oat straw further for related gluten allergies like avenin.
