Is Goldenseal safe while breastfeeding?
Here is what LactMed, the Drugs and Lactation Database published by the U.S. National Institute of Child Health and Human Development (NICHD), reports about Goldenseal. The text below is quoted from that source — it is not our own verdict.
Summary of use during breastfeeding
Goldenseal (Hydrastis canadensis) root contains berberine and other isoquinoline alkaloids. Goldenseal has traditionally been used as an anti-infective both systemically and topically, although high-quality studies of its efficacy and safety are lacking. It has also been used to mask illicit drugs in the urine, although it appears to be ineffective with modern laboratory methods. Goldenseal has been used topically by nursing mothers to treat sore nipples.[1] No data exist on the excretion of any components of goldenseal into breastmilk or on the safety and efficacy of goldenseal in nursing mothers. Berberine can displace bilirubin from serum albumin, causing concern about exposure of newborn infants, because bilirubin can build up in the infant's brain, causing brain damage.[2] However, the extent of berberine's passage from the mother to the infant is unknown. Most sources recommend avoiding exposure of neonates to goldenseal via breastfeeding or otherwise.[3-5]
Dietary supplements do not require extensive pre-marketing approval from the U.S. Food and Drug Administration. Manufacturers are responsible to ensure the safety, but do not need to prove the safety and effectiveness of dietary supplements before they are marketed. Dietary supplements may contain multiple ingredients, and differences are often found between labeled and actual ingredients or their amounts. A manufacturer may contract with an independent organization to verify the quality of a product or its ingredients, but that does not certify the safety or effectiveness of a product. Because of the above issues, clinical testing results on one product may not be applicable to other products. More detailed information about dietary supplements is available elsewhere on the LactMed Web site.

“No published information” means the studies do not exist yet — not that Goldenseal is known to be harmful, and not that it is known to be safe. Your prescriber or pharmacist can weigh your baby's age and whether a better-studied alternative would do the same job. Worth asking before stopping a medicine you need.
