Elderberry tree identification
Common elderberry or American elder (Sambucus nigra L. ssp. canadensis or just Sambucus canadensis) is a shrub that's commonly found throughout most of North America. Its characteristic cream-colored flowers, or elderflowers, are often seen on the road-side in late spring and early summer.
The flowers grow in umbels, which are sort of umbrella-shaped clusters. The umbels are normally six inches or so in diameter.
Once the elderflowers, also called elderblow, are finished, they yield to clusters of small dark purple berries that ripen mid-summer to early fall.
Elderberry trees have opposite, elongated, toothed leaflets that are three to four inches long.
Leaves, stems, bark and roots are toxic, so it's important to be vigilant about not including any of these when processing elderberries or elderflowers. The berries, bark and leaves have been used traditionally in medicinal preparations.
Watch out for Hercules' club which has similar leaves and berries -- the berries are poisonous. Hercules' club's berry clusters are flat instead of round, and the stems are covered in thorns, while elderberry stems are smooth.
Can You Eat Elderberries?
Cooked ripe elderberries are perfectly edible. Unripe elderberries are poisonous. Raw berries can cause nausea, vomiting, and diarrhea, among other symptoms, so be sure to cook them before eating. Cooking the berries also improves their flavor.
Elderberries can be baked into pastries, cooked into a syrup or dried for later use.
See our elderberry syrup recipe for a sweet, homemade cold season tonic.
The only edible parts of the elderberry tree are the berries and flowers.
What Are the Benefits of Elderberry?
Elderberries have long been used as a go-to remedy for treating and preventing all kinds of ailments. Here are a few peer-reviewed studies that corroborate what folk healers have known for ages.
Reducing duration of cold symptoms:
(Elderberry Supplementation Reduces Cold Duration and Symptoms in Air-Travellers: A Randomized, Double-Blind Placebo-Controlled Clinical Trial)
"Travellers using elderberry from 10 days before travel until 4–5 days after arriving overseas on average experienced a 2-day shorter duration of the cold and also noticed a reduction in cold symptoms. "
Antioxidant for disease prevention:
(The Phenolic Contents and Antioxidant Activities of Infusions of Sambucus nigra L.)
"The results of this study suggest that elder beverages could be an important dietary source of natural antioxidants for the prevention of diseases caused by oxidative stress."
(Elderberry flavonoids bind to and prevent H1N1 infection in vitro.)
"The Direct Binding Assay established that flavonoids from the elderberry extract bind to H1N1 virions and, when bound, block the ability of the viruses to infect host cells."
(A systematic review on the sambuci fructus effect and efficacy profiles.)
"Several in vitro studies together with two exploratory studies in humans and one open study in chimpanzees indicate that the aqueous elderberry extract Sambucol may be useful for the treatment of viral influenza infections."
"Although elder has been long advocated as an effective traditional plant treatment to counter the symptoms of diabetes..., scientific studies to evaluate its efficacy and possible mode of action are lacking. The present study reports for the first time that elder flowers contain water-soluble natural products which directly stimulate glucose metabolism by muscle and promote insulin secretion from clonal pancreatic β-cells."
"Sambucus nigra therefore represents a possible dietary adjunct for the treatment of diabetes and a potential source for the discovery of new orally active agent(s) for future diabetes therapy."
"Natural polyphenols extracted from S. nigra and A. melanocarpa modulate specific and non-specific immune defenses in insulin-deficiency diabetes and reduce the inflammatory status and self-sustained pancreatic insulitis."
(Antidepressant activities of Sambucus ebulus and Sambucus nigra.)
"Our report indicated the S. ebulus and S. nigra. extracts were safe and showed remarkable antidepressant activity in FST and TST in mice. These results introduced these plants as easily accessible source of natural antidepressant."
Here's a great video about the virtues of Elder by Rosemary Gladstar, one our favorite herbalists.
What Are the Benefits of Elderflower?
Elderflower shares some of the same healing properties as elderberries and has a few of its own. Here's some peer-reviewed research on some of those properties.
"The results confirmed that elderflower beverages (sabesa, syrup) should be recommended as a good source of phenolics in human diet."
Potential breast cancer treatment:
(Effects of Phytoestrogen Extracts Isolated from Elder Flower on Hormone Production and Receptor Expression of Trophoblast Tumor Cells JEG-3 and BeWo, as well as MCF7 Breast Cancer Cells)
"Our results clearly demonstrate beneficial features of EFE [elderflower extracts] in the setting of hormone receptor-positive breast cancer MCF7 cells by inhibition of estrogen secretion, downregulation of Erα, and upregulation of PR. Decreased local and circulating estrogen concentrations are certainly considered an advantage in treating breast cancer. In that view, EFE could be related to reduced tumor cell proliferation, possibly suggesting a protective effect on breast cancer. Nevertheless, the results and the conclusions made must be interpreted with caution as this is an in vitro cell culture study. In this setting, the use of plant extracts instead of chemically pure agents may be advantageous as it may more accurately reflect the effects of phytoestrogen-rich diets."
"The main findings from these studies are that elderflower extracts, their constituents and the corresponding flavonoid metabolites showed a major effect on the enhancement of glucose uptake and oleic acid uptake in human liver cells and human skeletal muscle cells."
"Elderflower constituents and metabolites also act as strong antioxidants and might play an important role in the controlling of postprandial hyperglycemia by strong inhibition of α-glucosidase and α-amylase. The antidiabetic properties found in phenolics from elderflower increase the nutritional value of this plant as a functional food against diabetes."
How to Harvest Elderflower
Harvest the flowers when they appear or leave them on the tree and come back for elderberries later. Less-traveled country roads are good places to forage for elderflowers and elderberries but stay away from busy roads (more about that in our foraging guidelines).
To harvest elderflowers, cut off flower heads with scissors, keeping in mind that flowers develop into berries and harvesting them will detract from berry production.
As a side note, call us superstitious, but we always ask permission before harvesting elderflower or berries. Actually, we do that for everything but this is an old tradition with the Elder tree.
How to Harvest Elderberry
What's tricky is getting to the berries before the birds get them, because they really start to disappear once they're ripe.
The best way to make sure you get to them before they're gone is to drape mesh or netting over the flowers. Be sure to leave space between the netting and the flowers to prevent berry damage from penetrating birds' beaks.
I always try to leave plenty for the wildlife that depends on elderries for food, taking only what I will reasonably use.
The process of harvesting the berries is basically the same as harvesting the flowers. Simply cut off the stems with scissors and put in a paper bag.
If you feel like doing something monotonous and meditative, then painstakingly pick every berry from its stem.
But if you'd like to get on with your day, put your paper bag full of elderberries in the freezer for an hour or so until the berries are completely frozen.
Then, making sure the bag is closed, shake it up a bit to help loosen the berries. For the berries that still aren't loose, just rub them away from the stems with your hands.
You can then put the berries into a bucket of water to help separate any debris that may be mixed in. Then pour off the water.
You can use the berries right away, freeze them, or dry them to use later.
How to Dry Elderflowers
Elderflowers can be used fresh or dried for later use. To dry, either lay the fresh flower heads on a piece of cardboard or hange them in a well-ventilated shady, dry area.
They're ready for storage when they can be easily brushed off of the stems. Store in air-tight glass jars or something similar.
How to Make Elderflower Tea
Elderflower is naturally sweet and makes an excellent floral tea that really doesn't need any added sweetener.
To make tea from fresh elderflowers, boil a pot of water and add two to four freshly cut elderflower heads to steep for 10 minutes.
If you're using dried elderflower, steep two teaspoons in a cup of boiled water for ten minutes.
Where Can You Find Elderberries?
The Common elderberry grows throughout most of the United States.
It's a really versatile tree that thrives in a variety of conditions, but it loves areas with lots of moisture and nitrogen. Look for it along streambanks, in damp woods, open fields, old homestead sites, and power line cuts.
While the elderflowers are blooming in late spring/early summer, it's easy to spot them growing in thickets along the road.
Elderberry Recipes and Uses
I just discovered this awesome video about making elderberry syrup with Sylvie Doré of Redwood Fairy Herbs & Ferments.
You can also check our our "super-charged" elderberry syrup recipe (complete with echinacea and turkey tail mushrooms) or just use this simple recipe:
6 cups water
1 cup dried elderberries or 2 cups fresh elderberries
1 cup honey
In a medium-sized sauce pan, water and elderberries, bring to a boil, lower heat and simmer, covered, for 30 to 40 minutes.
Remove from heat, strain out the seeds, and stir in honey (mixture should still be warm but not boiling).
Set aside to cool, pour into jars or bottles, and refrigerate for up to 3 months. Syrup can also be frozen in ice cube trays or plastic containers and stored for up to a year.
Elderflower Cordial Recipe
Elderflower cordial is a drink that dates back as far as the Roman Empire -- an ancient soft drink.
Traditionally, it's mixed with carbonated water before drinking, but this recipe makes a naturally bubbly sparkler -- no carbonated water needed.
We love making a big batch so that we can preserve and enjoy summer into the colder months.
3 1/2 cups caster sugar
2 cups hot water
4 large fresh elderflower heads
2 TBL white wine vinegar
juice or rind of 1 lemon
7 pints water
Fresh strawberry juice (optional)
Mix sugar and hot water.
Pour mixture into large glass container.
Add remaining ingredients and stir well.
Cover and let sit at room temperature for 5 days.
Strain liquid into sterilized screw- or flip-top bottles and let sit another week.
Serve cold and garnish with lemon, strawberry, and/or mint. Add fresh strawberry juice for flavor and color.
