Coriander
spice
Coriander, or Coriandrum sativum, is an annual herb in the family Apiaceae. The leaves are known as cilantro in the US. Most people perceive the leaves as having a fresh, slightly citrus taste. Due to variations in the gene OR6A2, some people perceive its flavor to be more soaplike or rotten.

Pregnancy, Breastfeeding & Children
No herb-specific pregnancy/child safety research is documented for Coriander in our references — the guidance below is based on its general effect category, not research on Coriander itself. Always confirm with a midwife, doctor, or pediatrician.
Pregnancy
Use CautionThis herb is processed through the liver, which is already working harder during pregnancy — generally used cautiously and not at high/concentrated doses without guidance. This is a general, mechanism-based caution, not herb-specific research.
Breastfeeding
Use CautionLiver-processed compounds can appear in breast milk — generally used cautiously and in moderation.
Children
Use CautionA child's liver is still developing its full drug/herb-processing capacity — these herbs are generally used cautiously and at reduced, age-appropriate doses.
As a member of the Apiaceae (carrot/celery) family, this herb is a known cross-reactivity group with birch pollen ("oral allergy syndrome") — use caution with a birch pollen or celery allergy.
Interactions & contraindications
May affect blood sugar
Watch for: Insulin and oral diabetes medications (metformin, sulfonylureas)
Additive blood-sugar-lowering effects can risk hypoglycemia — monitor glucose closely.
Processed by the liver
Watch for: Any medication that is also processed by liver enzymes (ask your pharmacist — this includes many common prescriptions)
Can alter how quickly the body clears certain medications, raising or lowering their effective dose.
May have a diuretic effect
Watch for: Diuretic medications and lithium
Additive fluid loss can affect electrolyte balance and change how the body clears lithium.
May affect immune activity
Watch for: Immunosuppressants (for transplant or autoimmune conditions)
Immune-stimulating herbs can work against immunosuppressive therapy.
