Why is barberry strongly advised against for women who are breastfeeding?

Answer

Compounds from the herb could pass through breast milk and potentially affect the infant

The concern regarding barberry use during lactation stems from the potential for the active components, particularly berberine, to transfer from the mother into her breast milk. Since the safety profile for newborns exposed to these compounds via milk has not been reliably established, caution is paramount. If these compounds are transferred, there is a risk they could exert unintended physiological effects on the developing infant, similar to the risks observed in newborns directly administered the substance, necessitating complete avoidance by nursing mothers.
