Elderberry: The Flu Fighter

| October 17, 2008

Sambucus nigra, a. k. a. Black Elderberry, Blue Elderberry

Elder was called the “country people’s medicine chest.”  Elder keeps viruses at bay by blocking the virus from entering the cell itself. All flu viruses have trouble with elderberry’s blockades. The symptoms of flus like coughs, sore throats and sinus congestion melt under this herb’s attention.

Elder is a graceful shrub with elegant arching branches, vibrant green leaves and white sprays of flowers that turn into irresistible berries at the end of summer. Black elderberry is native to Europe and North America. Its availability increases its appeal. The elder species have several variations. Elders that produce blue-black berries are considered to be in part of the Sambucus nigra species. Black and blue elderberries, in my opinion, taste the sweetest.

Medicinal Properties and Actions of Elderberry


Unripe Elderberry – Note Lack of White Berry Coating

Elderberry holds a bounty of flavonoids and triterpenes packed within its tiny fruit. These chemicals seem to be the key to elder’s anti-inflammatory, antiviral and immune stimulating effects. New research points to elderberry’s ability to block avian and human influenza viruses from connecting to cells throughout the body. Researchers are particularly pleased to see dangerous viruses like the swine flu virus included in the list of infections elderberry prevents.

Many symptoms connected to colds and flus are effectively treated with this tiny berry. Coughs, fevers and sinus infections all bow to elder’s healing touch.  This makes elderberry a rare herb as it not only prevents infection but also treats the infection after it’s taken hold.

Elder is an important herb for the immune system, but it needs to be used as a daily supplement. Elder constituents do not cling to the tissue, which means daily treatment is not only safe but necessary to block viruses. It doesn’t overtax the immune system or cause imbalances in the digestive tract that allow yeast infections to take hold, either, making it safe for daily consumption.

Conditions Best Helped by Elderberry

Elderberry is best for flus and symptoms of flus. It stimulates the immune system in ways that also prevent herpes simplex from taking a hold in the body. Scientists hope this immune stimulation will prove to be useful against more serious infections like HIV. Elderberry has Sambucus nigra agglutinins (SNAs) that keep the cell walls barred against viruses.

People with compromised immune systems due to allergies or asthma benefit from this herb’s attention. Those who suffer from bronchitis would do well to add elderberry into their diet as well.

Elder flower has been traditionally used to treat skin inflammations. It’s useful in creams and ointments. A rash caused by allergies or bug bites can be soothed by elder flower after just a few treatments. Many years ago, Elder Flower Water was a common skin treatment for sunburn and pimples. It was said to contain elder flower tea, glycerine and borax.

Medicinal Processing


Elder Flower and Fruit with Tea

Elderberries and elder flowers make wonderful tinctures. The herbs may be processed with a 1:1 plant weight to solvent weight ratio. It is processed with about 50 percent water to 50 percent pure alcohol. The range is flexible with this plant, so feel free to play around with what suits your needs best. Brandy is a perfect alcohol with which to to process elderberries and elder flowers since it’s generally around 100 proof thus it needs no watering down.

Elderberry makes a delicious syrup or moxey. It’s easy to cook into glycerite in a slow cooker or the stove top. The natural sweetness of the berries cook easily in to syrup so less cooking time is required. A standard 70 percent glycerin to 30 percent water formula is required. The usual weight ratio is 1:5 or 1:4 depending on the strength required.

Elder tea is an excellent way to start a morning and stave off the flu viruses lingering in the rest of the day. Drying elder flower takes only a day or two upside down away from light. Elderberries should be dried in a food dryer or in the oven on low for a few hours. Check the berries frequently so they do not over dry and become tasteless.

Elderberry may be frozen or cooked into jams or jellies. If you want a creative way to introduce elderberry as medicine into the lives of your family, try spreading their medicine on toast. The jam is a little seedy, but it may be combined with blackberries or raspberries if need be.

Gardening and Gathering Elderberries


Elderberry likes to grow in damp, well-drained, fertile soil. It does best in full sun but will also tolerate partial shade. Soil acidity of 5.5 to 6.5 is optimum. A light, airy place, such as in the middle of a field, will offer elder the best opportunity to develop into a tree with a wide, airy canopy.

Elder can also be planted as a hedgerow, which will take goodly shape within roughly three seasons. Regular spring pruning after the third year is advised if you want to encourage an abundant crop of flowers and berries.

Propagation of elder is from hardwood or softwood cuttings and from suckers or rootstock. Expect your first elder flower and berry harvest in the third year after planting. Elder is shallow rooted, so watering well during the first year and possibly the second is wise.

For more information on elder propagation, see elderberries.com.

Gathering Elder Flowers and Elderberries

Flowers are picked in spring when the buds have first opened. Be certain to leave plenty of flowers on each bush so plenty of berries will form and ripen for all to enjoy. As elder is an early bloomer, its flowers offer an excellent food source to native pollinators, making reserved harvest of elder flowers that much more important. Do not consume the elderberry stems since they contain trace amounts of cyanide.

Elderberries are ready to eat at the end of summer and often are even tastier well into fall if the weather remains warm. Pick the entire cluster to separate later. Leave enough for wildlife on each bush. Elderberries dry on the stem and offer cold weather fruit to hungry birds in winter.

Be certain  you have your elderberry identified properly. Red elderberries are not known to be edible. There is no problem with red elder’s flower however.

Using Elderberries to Care for Animals

elderberrychickenElderberry is safe to feed birds in small doses. I like to give my chickens an elderberry supplement when the cold autumn weather comes in. Birds are susceptible to respiratory diseases. Add a few dried elderberries to the feed dish when conditions grow damp or if your bird starts to look listless.

Wild birds are big fans of native elderberry. As elderberries dry on the twig, this becomes a valuable food source when wild fruit sources disappear. Bird watchers do well to plant a native elder bush in their yard. It is sure to be busy with feathered friends all year round.

Elderberry syrup or glycerite is easy to feed to a sick pet with an herbivore or omnivore diet. An elderly animal like a dog or a goat with a compromised immune system will tolerate the pressures of winter with the help of a daily dose of elderberry. Cats are carnivores and don’t medicate without a battle. Good luck.

Household Formulas and Non-medicinal Uses of Elderberry

Elder flowers and berries have been used as beauty treatments since the middle ages. Mixed with vinegar or water, elder berries are reputed to make a good dye for black to brown hair. Washes made with elder flowers were used to lighten the skin. Today, elder flower infusions provide a gentle astringent with healing properties for normal to dry skin. Elder flowers are also used occasionally in perfumes and are said to provide relief to irritable skin and nerves when used in the bath.

Elder can be used in incense formulas, particularly those designed to provide protection against those who would infringe on your boundaries or do you harm or  designed to honor a crossing, such as a death or birth, or to invoke the guardian who stands at the gateway you desire to cross.
