Black elder is one of the most deeply rooted plants in European infusion traditions. Its delicately scented white flowers are harvested in spring, then dried to be steeped in autumn and winter, at the heart of the cold season. This page covers the traditional uses, how to prepare the infusion properly, and the important precautions to be aware of (yes, elder does have real contraindications worth knowing).

Elder: a flower with traditional uses

Sambucus nigra is listed in the HMPC community herbal monograph of the EMA (European Medicines Agency). Elder is listed there for its long-standing use as an infusion. This use reflects several centuries of documented tradition across Europe.

The flowers contain flavonoids (rutin, quercetin), phenolic acids, essential oils and mucilages. This composition partly explains the traditional uses:

• A flower traditionally associated with the cold season, in a comforting infusion.
• A gentle sudorific character that tradition links to warm winter drinks.
• A plant found in the infusion rituals of spring.
• A warm drink appreciated for its delicate floral character.

Elder has been the subject of research work, focusing mainly on the berries (rather than the flowers). The use of the flowers in a classic infusion belongs to tradition, well established over the centuries across Europe.

Flowers, berries, bark: what you need to know

Not all parts of the black elder plant are used in the same way, and some carry real risks.

• Dried flowers are the most commonly used part in herbal infusions. Well tolerated at recommended doses.
• Cooked berries are used to make syrups, jams and liqueurs. They are rich in anthocyanins and vitamin C.
• Raw berries contain sambunigrin, a cyanogenic glycoside that is toxic. NEVER consume them raw: nausea, vomiting and severe digestive upset are possible. Cooking above 80 °C (175 °F) destroys this compound.
• The bark and leaves are also high in sambunigrin. Avoid for home use unless advised by a qualified phytotherapy practitioner.

For an infusion, stick to dried flowers from organic black elder. This is the safest and best-documented form.

How to make a good elderflower infusion

Elder flowers release their compounds in 10 minutes of steeping. Here's how to do it right:

• Quantity: 1 tablespoon (about 2 g) of dried flowers per 250 ml cup.
• Water: bring to just below boiling (95 °C / 200 °F). Avoid prolonged boiling, which degrades the aromatic compounds.
• Steeping time: 10 minutes, with the cup covered to retain the volatile essential oils.
• Straining: pour through a fine sieve. You can add a teaspoon of honey and a squeeze of lemon juice to soften the taste.
• Frequency: 2 to 3 cups per day during the period of discomfort, over a short course of 5 to 7 days.

Elder pairs particularly well with other plants suited to the cold season:

• Elder + thyme: a classic combination among cold-season infusions. See our thyme herbal infusion guide.
• Elder + lemon + honey: a time-honored home remedy, validated by generations of use.
• Elder + blackcurrant + meadowsweet: a trio with woodland, tangy notes.
• Elder + ginger: for a warming, lively infusion. Our ginger herbal infusion guide covers this use in detail.

When to drink an elderflower infusion

The best time depends on what you're looking for:

• As a winter ritual: 1 cup per day, over a one-week course, repeated several times throughout the cold season.
• Through the cooler days: 2 to 3 cups per day, over a short 5 to 7 day course.
• In spring: 1 to 2 cups per day, as a warm pause through the season.
• In the evening: preferable, as the mild sudorific effect can be uncomfortable during an active day.

Precautions and contraindications

An elderflower infusion is generally well tolerated, but a few rules apply:

• Raw berries, bark and leaves: NEVER consume without cooking. Sambunigrin is a precursor to hydrogen cyanide.
• Pregnancy and breastfeeding: use of the flowers warrants caution. The ANSES recommends seeking medical advice before regularly drinking any herbal infusion during pregnancy.
• Children: an elderflower infusion is generally acceptable from the age of 6, in moderate amounts (1 cup per day maximum).
• Diuretic treatment: the mild diuretic effect of elder may be additive. Monitor hydration and let your doctor know you are using it.
• Immunosuppressant medications: as a precaution, ask your doctor's advice if you are on post-transplant treatment or managing an autoimmune condition before regular consumption.
• Allergies: rare, but possible in people sensitive to Adoxaceae pollens.

If you have a fever lasting more than 48 hours, difficulty breathing, or any worrying symptoms, consult a doctor. An herbal infusion is a complement, not a treatment.
