St. John's Wort
St. John's Wort is a popular herbal supplement for mild depression, but it should be used cautiously while breastfeeding. Small amounts do transfer into breast milk, and case reports have noted colic, drowsiness, and lethargy in some breastfed infants. It also interacts with many medications — including birth control pills, reducing their effectiveness.
St. John's Wort contains hyperforin and hypericin, which have antidepressant properties. Studies have detected these compounds in breast milk, though at relatively low levels. Some case reports describe colic and lethargy in breastfed infants of mothers taking St. John's Wort, though larger studies have not found consistent adverse effects. A major concern is drug interactions: St. John's Wort is a potent inducer of CYP3A4 enzymes and P-glycoprotein, which means it can reduce the effectiveness of many medications including oral contraceptives, SSRIs, warfarin, and cyclosporine. If considering it for postpartum depression, prescription antidepressants like sertraline have much more safety data.
Safer Alternatives:
Always confirm with your doctor or lactation consultant before making dietary changes while breastfeeding.
