What is Elderberry?

Elderberry refers to the dark purple berries of the Sambucus nigra plant, a flowering shrub native to Europe and parts of North America. The plant has a long history in folk medicine, used for everything from treating colds and flu to reducing inflammation and soothing skin conditions.

The berries grow in clusters and are typically harvested in late summer to early autumn. While the flowers can also be used to make tea, the berries are the primary source of the potent bioactive compounds that make elderberry so popular in the wellness world.

The key health-promoting compounds in elderberry include:

Anthocyanins — powerful antioxidants that give the berries their dark purple color
Vitamin C — an essential immune-supporting nutrient
Dietary fiber — supporting digestive health
Flavonols — anti-inflammatory and cardiovascular-supportive compounds
Phenolic acids — additional antioxidant properties

It’s important to note that raw elderberries contain cyanogenic glycosides, which can cause nausea if consumed in large quantities. This is why elderberry is almost always consumed cooked—either as a tea, syrup, or extract.

Top 8 Science-Backed Benefits of Elderberry Tea

1. Potently Supports Immune Function

This is elderberry’s most celebrated benefit. Multiple clinical studies confirm that elderberry extract has a significant impact on immune function, particularly during cold and flu season.

A landmark study published in the Journal of International Medical Research found that air travelers taking elderberry extract experienced significantly fewer cold symptoms—averaging 4 days shorter duration—compared to those taking a placebo. The study, which tracked 312 economy-class travelers from Australia, noted that participants taking elderberry experienced a 38% reduction in cold symptom duration and a 50% reduction in overall symptom severity.

Another study published in Nutrients found that elderberry supplementation (500 mg daily) significantly increased inflammatory cytokine production in healthy individuals after 4 weeks, suggesting a general immune-supportive effect even in the absence of active illness.

2. Reduces Duration and Severity of Cold and Flu Symptoms

Building on its immune-supportive properties, elderberry has demonstrated specific effectiveness against influenza viruses.

A 2016 study published in Pharmaceuticals found that elderberry extract showed potent inhibitory activity against influenza A and B viruses in cell cultures. The compounds in elderberry appear to work by preventing the viruses from entering and replicating within cells.

A randomized, double-blind, placebo-controlled study—the gold standard in clinical research—found that patients with influenza-like symptoms who took elderberry syrup (15 mL four times daily) experienced symptom resolution an average of 4 days earlier than those taking a placebo. The elderberry group also required significantly less medication (e.g., pain relievers and decongestants) to manage their symptoms.

3. Rich in Antioxidants That Combat Oxidative Stress

Elderberry is one of the most antioxidant-dense berries available, second only to blackcurrants among commonly consumed fruits.

A study published in the Journal of Agricultural and Food Chemistry analyzed the antioxidant capacity of various berries and found that elderberries scored significantly higher than blueberries, cranberries, and raspberries in ORAC (Oxygen Radical Absorbance Capacity) assays. Anthocyanins, the pigments responsible for elderberry’s deep purple color, are the primary drivers of this antioxidant activity.

Antioxidants work by neutralizing free radicals—unstable molecules that cause oxidative damage to cells and are linked to aging, inflammation, and chronic diseases including heart disease, cancer, and neurodegenerative conditions like Alzheimer’s.

4. Supports Cardiovascular Health

The antioxidant and anti-inflammatory properties of elderberry extend to cardiovascular health. Several mechanisms are at play:

Lowers cholesterol: A study in the European Journal of Clinical Nutrition found that consuming 400 mg of elderberry extract daily for 4 weeks led to a 15% reduction in LDL (“bad”) cholesterol and an 18% increase in HDL (“good”) cholesterol in participants with mild hyperlipidemia.

Reduces blood pressure: The anthocyanins in elderberry have been shown to support healthy blood pressure levels by promoting the relaxation of blood vessels and reducing arterial stiffness.

Anti-inflammatory effects: Chronic inflammation is a key driver of atherosclerosis (hardening of the arteries). By reducing inflammatory markers, elderberry may help protect against the development of cardiovascular disease.

5. May Have Anti-Cancer Properties

This is one of the most exciting areas of elderberry research. While not a cure for cancer, laboratory studies suggest elderberry compounds may have anti-proliferative effects on cancer cells.

A study published in the Journal of Cancer Research and Clinical Oncology found that elderberry extract significantly inhibited the growth of colon cancer cells in vitro. The researchers attributed this effect to the high concentration of anthocyanins, which appeared to induce apoptosis (programmed cell death) in the cancer cells while leaving healthy cells largely unaffected.

Another study in the Journal of Medicinal Food found that elderberry extracts showed anti-proliferative activity against breast cancer and brain tumor cell lines. More research—particularly human clinical trials—is needed, but the preliminary results are promising.

6. Supports Digestive Health

Elderberry is a good source of dietary fiber, with approximately 7 grams of fiber per 100 grams of fresh berries. Fiber is essential for maintaining a healthy digestive system, supporting regular bowel movements, and feeding the beneficial gut bacteria that make up the microbiome.

The prebiotic effects of elderberry fiber may also contribute to improved immune function, since a significant portion of the immune system resides in the gut. Additionally, the anti-inflammatory properties of elderberry’s anthocyanins may help soothe digestive tract inflammation.

7. May Improve Skin Health

The antioxidants in elderberry don’t just work internally—they can also benefit the skin. Anthocyanins have been shown to support collagen production and protect skin cells from UV-induced damage.

Elderberry is also a natural source of vitamin A (in the form of carotenoids), which is essential for maintaining healthy skin cell turnover. Some skincare researchers have specifically noted elderberry’s potential as an anti-aging ingredient due to its ability to neutralize free radicals that contribute to wrinkles and age spots.

Topical elderberry extracts are increasingly found in premium skincare products, though drinking elderberry tea offers systemic antioxidant benefits that may support skin health from within.

8. Supports Respiratory Health

Elderberry’s traditional use for treating respiratory infections has received scientific support in recent years. Beyond its direct antiviral effects, elderberry appears to help with the congestion, inflammation, and sinus discomfort that often accompany colds and allergies.

The anti-inflammatory properties of elderberry’s flavonoids can help reduce swelling and irritation in the nasal passages and throat. Some practitioners of integrative medicine specifically recommend elderberry for seasonal allergy support due to its ability to modulate inflammatory responses.

How to Prepare Elderberry Tea

Elderberry tea is typically made from dried elderberries, elderberry flower, or tea bags containing powdered elderberry. Here’s how to make it:

Basic Elderberry Tea:
– Use 1–2 teaspoons of dried elderberries (or 1 tea bag) per cup of water
– Bring water to a boil, then add elderberries
– Reduce heat and simmer for 10–15 minutes
– Strain and enjoy
– Add honey for sweetness, or blend with lemon or ginger for extra benefits

Elderberry and Ginger Tea (Immunity Boost):
– Combine 1 teaspoon dried elderberries with 3–4 slices of fresh ginger
– Add a squeeze of lemon juice
– Steep in hot water for 10–15 minutes
– Strain and add honey to taste

Elderflower Tea:
– Use 1–2 teaspoons of dried elderflowers per cup
– Pour boiling water over the flowers
– Steep for 5–10 minutes
– Strain and enjoy warm or iced

Safety note: Always use cooked elderberries (as in tea)—never eat raw elderberries, bark, or leaves from the elder plant, as these contain compounds that can cause nausea and digestive upset.

Potential Side Effects and Considerations

While elderberry tea is generally safe for most people when consumed in moderation, there are some important considerations:

Raw berries are toxic — Never consume raw elderberries, which contain cyanogenic glycosides that can cause nausea, vomiting, and diarrhea. Cooking destroys these compounds.
Autoimmune conditions — Because elderberry may stimulate immune activity, individuals with autoimmune diseases such as rheumatoid arthritis, lupus, or multiple sclerosis should consult a healthcare provider before use.
Medication interactions — Elderberry may interact with immunosuppressants, diabetes medications, and diuretics. If you’re on any medications, check with your doctor.
Pregnancy and breastfeeding — There is insufficient safety data for elderberry during pregnancy or breastfeeding. Consult a healthcare provider.
Allergies — Individuals allergic to other plants in the Caprifoliaceae family (including honeysuckle and viburnum) should use caution.
Surgery — Due to its potential immune-stimulating effects, it is generally recommended to stop taking elderberry at least two weeks before scheduled surgery.
