Is elderberry safe during pregnancy?

What does the evidence say about elderberry during pregnancy?

1. Some early research suggests elderberry may ease flu, cold, or other upper-respiratory symptoms in adults generally. 1
2. Raw or unripe elderberries, along with the leaves and stems of the plant, contain a substance that can cause nausea, vomiting, and severe diarrhea. Cooking removes this toxin. 1
3. The evidence on elderberry for colds is still limited overall, and there aren't large controlled studies in pregnant women to support routine use during pregnancy. 2
4. Supplement makers in the U.S. aren't required to prove safety or purity before selling a product, so what's actually in the bottle can differ from what the label says. 3

Is elderberry safe in each trimester?

• First trimester. This is the least-studied window, and it's when the baby's organs are developing. Most providers suggest skipping elderberry supplements in the first trimester unless yours specifically recommends it.
• Second trimester. Some second-trimester use has been reported without documented harm, but the studies are too small to draw firm conclusions. Check with your provider before using it.
• Third trimester. Herbs that affect the immune system, like elderberry, are usually set aside close to delivery. Lean on well-studied approaches for immune support instead, and coordinate with your provider.
