Elderberry syrup is one of the oldest home remedies still in regular use. It is also one of the most oversold.
Long before it showed up as gummies at the grocery store checkout, families were cooking down dark purple elderberries into syrups, jams, and cordials to get through the cold months. The tradition is old. The research is newer, smaller, and more interesting than most labels let on.
We started to make elderberry syrup a few years ago. I tried to buy it, but it had pasteurized honey in them, and some even had straight sugar. I knew if I wanted to get all of the benefits, we would need to make it ourselves.
Here's what elderberry is, what the studies actually show, how to use it safely, and how to make a batch in your own kitchen.
What elderberry is
Most elderberry syrup is made from Sambucus nigra, the European black elder, or its North American cousin, Sambucus canadensis. It's a shrub that puts out flat clusters of white flowers in early summer, then heavy, drooping clusters of tiny dark berries by late summer.
Those berries are rich in anthocyanins, the same pigments that make blueberries and blackberries so dark. They also carry vitamin C, fiber, and flavonoids like quercetin. Anthocyanins are antioxidants, and they're where most of the research interest sits.
What the research says
The honest version: promising, small, and not settled.
Colds. A 2016 study followed 312 air travelers flying from Australia overseas. Travelers taking elderberry extract who still caught a cold were sick about two days less on average, with milder symptoms.
Cold and flu symptoms. A 2019 meta-analysis pooled randomized trials covering 180 participants and found elderberry substantially reduced upper respiratory symptoms.
Flu. Smaller trials in the 1990s and early 2000s found people with flu recovered several days sooner on elderberry than on placebo.
So elderberry is not a shield, a cure, or a replacement for your doctor. It's a nutrient-dense food with a reasonable body of early evidence behind it. For our family, that's enough to keep a jar in the fridge from fall through spring.
Three rules for using elderberry safely
1. Always cook it. Raw or unripe berries, along with the stems, leaves, and seeds, contain compounds that can release cyanide in the body and cause nausea, vomiting, and diarrhea. Simmering breaks those compounds down. Never eat raw berries or the uncooked mixture, and strain out the solids. If you forage, be certain of your plant. Red elderberry (Sambucus racemosa) is a different species and is not the one you want.
2. No honey for babies under one. Raw honey can carry botulism spores that an infant's gut can't handle. Elderberry itself hasn't been studied in infants, so skip the syrup for babies and ask your pediatrician.
Why make it at home
Pick up a bottle of store-bought elderberry syrup and read the label. In many brands, a sweetener like glucose syrup or cane sugar is listed before the elderberry.
Making it yourself puts you in charge of three things: what sweetens it, how concentrated it is, and what it costs per ounce. It takes about an hour, and most of that is the pot simmering while you do something else.
How to make elderberry syrup
You'll need: dried elderberries (plus any spices you like), 6 cups water, about ¾ cup raw honey, a medium pot, a fine mesh strainer or cheesecloth, and a glass jar.
- Simmer. Combine the berries, spices, and water in the pot. Bring to a boil, then drop to a simmer with the lid cracked. Let it go 45 minutes to an hour, until the liquid has reduced by about half.
- Strain. Mash the berries with a spoon, then pour everything through your strainer or cheesecloth. Squeeze out as much liquid as you can and discard the solids.
- Cool, then sweeten. Let the liquid cool until it's warm, not hot, before stirring in the raw honey. High heat breaks down the enzymes that make raw honey worth buying.
- Store. Pour into a glass jar and refrigerate. It keeps 2-3 months. For longer storage, freeze it in ice cube trays and thaw a few days' worth at a time.
How much to take. A common approach is 1 tablespoon daily for adults and 1 teaspoon for children, taken more often during cold and flu season.
Add-ins worth knowing about. Elderberry is the base, but a few additions earn their place:
- Rose hips add vitamin C and a bright, tart edge.
- Hibiscus adds more tartness and a deep red color.
- Ginger, cinnamon, and cloves bring warmth and round out the flavor.
Getting started
If you'd rather not source six ingredients separately, we put together an Elderberry Syrup Kit with dried elderberries, rose hips, ginger, hibiscus, cinnamon sticks, and cloves, measured for one batch and makes around 4 cups. You add the water and honey.
Elderberry won't keep every cold out of your house. Nothing will. But a jar you made yourself, from ingredients you can name, is a good place to start.
