The Spices in Chai: Safety by Ingredient
This is the part of the chai pregnancy question that matters most โ and the part most articles handle vaguely. Here's a specific breakdown by spice, based on what the evidence says at typical chai tea doses:
๐ซ Ginger
Well-studied in pregnancy โ actually recommended for nausea by ACOG. Studies show up to 1g/day is considered safe and effective for morning sickness. Chai contains far less than this per cup.
โ
Safe
๐ฟ Cardamom
No evidence of harm at food or tea doses. Anti-inflammatory, digestive benefits. The amounts in chai โ typically a pod or fraction of a teaspoon โ present no known risk during pregnancy.
โ
Safe
๐ฐ Cinnamon
Cassia cinnamon (the common variety) contains coumarin, which at very high doses has blood-thinning properties. At culinary and tea doses, research does not show harm during pregnancy. Avoid cassia cinnamon supplements; tea is fine.
โ
Safe in tea
๐ธ Cloves
Used in small amounts in chai blends. High-dose clove oil has uterine-stimulant properties, but the fraction of a clove in a tea blend presents no established risk. Food doses are considered safe.
โ
Safe in tea
โซ Black Pepper
A small amount of black pepper appears in some chai blends for warmth. Standard culinary and tea doses show no adverse pregnancy effects. Safe as used in chai.
โ
Safe
โญ Star Anise
Some chai blends use star anise (distinct from licorice root but similar compounds). The National Institutes of Health and ACOG advise caution with large amounts. At tea doses, limited but inconclusive evidence โ use modest amounts.
โ ๏ธ Limit
๐ฟ Licorice Root
ACOG and European food safety authorities (EFSA) explicitly advise avoiding licorice root during pregnancy. Glycyrrhizin can disrupt cortisol metabolism and has been linked to preterm birth and cognitive effects in offspring in prospective studies. This is the one real concern in chai blends.
โ Avoid
โ ๏ธ Licorice Root in Chai โ The Real Concern
Some chai blends โ particularly "spiced chai" or "masala chai" products from specialty tea brands โ include licorice root for sweetness and depth. ACOG advises avoiding licorice root during pregnancy. A 2009 Finnish cohort study published in the American Journal of Epidemiology found that children whose mothers consumed high amounts of licorice during pregnancy had lower cognitive test scores at 8 years old. The EFSA echoed this concern. Check your chai blend ingredient list before every purchase.
Traditional Indian masala chai (ginger, cardamom, cinnamon, cloves, black pepper + black tea) contains no licorice root and is considered safe during pregnancy. The licorice concern applies to Western commercial blends that add it for sweetness. Read the ingredient list.
