Elderflower | Sambucus nigra | Family: Adoxaceae (formerly known as the Honeysuckle or Moschatel family)

Elderflower, the creamy white blossom of the elder tree, has long been cherished in herbal medicine for its fragrant aroma and remarkable healing powers. Revered for thousands of years, this ancient herb supports the respiratory system, soothes fevers, and assists in the gentle elimination of toxins. Both the flowers and berries of the elder tree hold valuable medicinal properties, making it one of nature’s most generous plants.

The Elder was one of the sacred trees of the Celts, known as Ruis the Elder, representing the thirteenth lunar month. Across Europe, it has been surrounded by folklore said to be both protective and magical. Native to Europe and North America, elder trees thrive along roadsides, forest edges, and fields.

There are two main species:

  • European elderberry (Sambucus nigra) – up to 20 feet tall
  • American elderberry (Sambucus canadensis) – shorter
    A related species, red elderberry (Sambucus racemosa), bears poisonous berries and should not be used.

Elderflowers bloom in late spring to early summer, depending on climate, with their short flowering window offering a precious time to harvest

Traditional and Therapeutic Uses

Respiratory & Immune Support

Elderflower shines in treating colds, flu, sinus congestion, and fevers. Its diaphoretic (sweat inducing) action helps the body regulate temperature and eliminate toxins through the skin. Rather than suppressing a fever, elderflower works in harmony with the body’s natural immune response enhancing the healing process.

It is especially indicated in catarrhal conditions such as sinusitis, tonsillitis, hay fever, and allergic rhinitis, helping to clear mucus and ease inflamed tissues.

Herbalists often combine elderflower with peppermint and yarrow during influenza or feverish colds to support the immune system and promote healthy sweating.

Note: Persistent or unexplained fevers may indicate a serious condition requiring medical care.

Circulation and Elimination

Elderflower promotes gentle detoxification by stimulating the skin and lymphatic system. As a diuretic and peripheral vasodilator, it helps move fluid through the body, relieving oedema and improving circulation to the extremities. These actions make it supportive for both skin health and hormonal balance.

Skin and Topical Uses

Thanks to its anti-inflammatory and antioxidant properties, elderflower can calm irritated, inflamed, or allergic skin.
It may be used externally as:

  • poultice or wash for rashes and eczema
  • cool infusion for tired or itchy eyes
  • bath addition to soothe the skin

Historically, Victorian women used elderflower water to cleanse and brighten the complexion  a practice now enjoying a revival in natural skincare.

Research Insights

Modern studies primarily focus on elderberries, yet promising research supports elderflower’s role as an immune modulator and antioxidant:

  • Phenolic compounds in elderflower exhibit strong free radical scavenging activity, protecting against cellular damage.
  • Polysaccharides from elderflower extracts may enhance immune cell activity, supporting recovery from viral infections.
  • Emerging neuroprotective research suggests elderflower may help reduce cellular stress in brain tissue.

Though more clinical studies are needed, traditional use and laboratory evidence continue to affirm elderflower’s healing reputation.

Safety and Dosage

Elderflower is generally safe when used appropriately.
Precautions:

  • May lower blood sugar; use caution with diabetes or anti-diabetic medications.
  • May interfere with blood sugar control during or after surgery.

Dosage:
Tincture (1:5 in 40%) — 2–4 ml, three times daily.
