What is elderberry?
Elderberry is a small purple berry from a tree (Sambucus) common in Europe and North America. That's why Sambucus often appears in product names.
It's rich in polyphenols and flavonoids (antioxidants plants make to protect themselves), like the anthocyanins that give it its purple color.
In the US and Europe, elderberry syrup is easy to find on pharmacy shelves as something to take when you feel a cold coming on.
Elderberry benefits: does it help with colds?
Elderberry may support the immune system in these ways:
- Calming inflammation: Its polyphenols help calm excessive inflammation and keep the immune system balanced.
- Indirect defense against viruses: One explanation is that anthocyanins make it harder for viruses and bacteria to latch onto your cells.
- Antioxidant support: It helps reduce free radicals (compounds that "rust" your cells).
How strong is the evidence?
| Topic | Summary |
|---|---|
| Symptoms of colds and upper respiratory infections (nose and throat) | Several sets of data show symptoms improved and illness was shorter |
| Size of the effect | How much it helps isn't clear yet |
Who it's right for
- □ You catch a cold every time the seasons change
- □ Your cough lingers after a cold
- □ Your kids often bring colds home from daycare or school
- □ You're looking for a gentle supplement to try before medication
How to take elderberry and how to choose it
- Focus on seasonal changes and cold season. It isn't a supplement to take all year.
- Follow the label for the dose. For kids, always use a children's product and dose.
- A bottle of syrup doesn't last very long. Think of it as something to have ready for cold season.
What to look for
- Form: Syrup is easy for both kids and adults. Capsules and gummies are also available if you take it daily.
- Extract content: Products that list a standardized (consistent) anthocyanin content are easier to compare.
- Sugar: Syrups and gummies can contain a fair amount of sugar. Check if you give it to your kids every day.
Cautions
- Don't eat raw or unripe berries, leaves or stems. They can cause nausea or vomiting. Store-bought products are processed, so they're fine.
- If you have a high fever, trouble breathing, or symptoms that last more than a week, don't rely on supplements — see a doctor.
- If you take immunosuppressants, or you're pregnant or breastfeeding, talk to your doctor first.
Medications and conditions to watch
- Note Immunosuppressants — May affect immune response — talk to your doctor
Combinations
