How to Make Elderberry Syrup

Elderberry syrup is easy to make at home for a fraction of shop prices. There is one rule that matters: cook the berries properly.

Safety first

• Raw elderberries are toxic. They contain cyanogenic glycosides that cause nausea, vomiting and diarrhoea. Cooking destroys them.
• Never eat the leaves, bark, roots or stems. Only the ripe cooked berries.
• Remove all green stems. Use a fork to strip berries from the umbels; discard the stems.
• Simmer at least 20–30 minutes, and do not eat the mixture before then.

The recipe

• 1 cup dried elderberries (or 2 cups fresh, de-stemmed)
• 3 cups water
• 1 cinnamon stick, optional
• 3–4 cloves, optional
• 1 tablespoon fresh ginger, optional
• 1 cup raw honey

Method

1. Combine berries, water and spices in a saucepan.
2. Bring to a boil, then reduce and simmer covered for 30–45 minutes, until reduced by about half.
3. Mash the berries against the side of the pan and strain through a fine sieve or muslin. Press well.
4. Let it cool below 40°C / 104°F before adding honey — heat destroys honey's enzymes and flavour.
5. Stir in the honey until dissolved. Bottle in a sterilised jar.

Yield: roughly 1½ cups from these quantities. It keeps about 2–3 months in the fridge, or 6+ months if frozen in ice cube trays.

Dosage

What the evidence says

Elderberry has small trials suggesting it may shorten influenza duration by a few days. The trials are modest and some were industry-funded. It is reasonable as a supportive measure, not a treatment.

It is not a substitute for flu vaccination or medical care.

Who should avoid it

• Autoimmune conditions — elderberry stimulates the immune system, which may be counterproductive
• Immunosuppressant medication — possible interaction
• Pregnancy and breastfeeding — insufficient safety data
• Children under 1 — because of the honey
• Anyone with a nightshade or daisy-family allergy — rare cross-reactions

If you cannot find elderberries

Dried elderberries are sold online and in health shops. Frozen ones work too — use 2 cups and simmer the same way. Do not substitute other berries; the recipe depends on elderberry specifically.

Common questions

Are raw elderberries poisonous?

Yes. Raw berries, leaves, bark and stems contain cyanogenic glycosides. Cooking for 20-30 minutes destroys them.

How long does homemade elderberry syrup last?

About 2-3 months in the fridge. Frozen in ice cube trays it keeps 6 months or more.

Can children take elderberry syrup?

Over one year old, at about 1 teaspoon daily. Never under one, because of the honey.

Does elderberry syrup actually work?

Small trials suggest it may shorten flu duration by a few days. Evidence is modest. It is not a replacement for vaccination.
