Elderberry has been getting a lot of respect in the media in recent years, but it has long been revered by Naturopathic Doctors and herbalists as a potent immune booster and medicine for the prevention and treatment of influenza.
What is Elderberry?
Elderberry, or Sambucus nigra is one species of elder that is grown primarily in Europe and western Asia. It is a shrub or small tree that has small black berries. The leaves, twigs, branches, seeds, roots and unripe berries are toxic due to the presence of a cyanogenic glycoside. The ripe berries are safe to eat (once cooked) and are used to make syrups, liquors and medicines.
Elderberry and Influenza
Multiple studies have been published in the past decade that support the use of elderberry to prevent the flu, treat symptoms of the flu and to decrease duration and severity of the flu.
A study published in the scientific journal, Phytochemistry (2009 Jul;70(10):1255-61) compared elderberry to Tamiflu (Oseltamivir) and Amantadine – two pharmaceutical drugs used in the treatment of influenza, including H1N1 (“swine flu”). The researchers found that elderberry inhibited H1N1 infection in people by binding to H1N1, blocking the entry of the virus into cells and preventing infection.
An older study published in the Journal of Alternative and Complementary Medicine compared the use of elderberry to placebo and found that elderberry decreased the symptoms of influenza (including fever) within 2 days and achieved a cure of influenza in 2 days in 90% of the group receiving elderberry, compared to 6 days with placebo. The most interesting thing about this study is that it was looking at Influenza type B – a type of influenza that Tamiflu and Amantadine are not effective in treating.
Elderberry has other distinct advantages over Tamiflu and Amantadine. The use of prescription Tamiflu and Amantadine is limited by the potential for side effects. Common side effects of these drugs include insomnia, restlessness and anxiety. No side effects of medicinal elderberry have been reported in clinical studies in adults and children.*
*Consumption of raw and unripe berries, seeds, and other plant parts can cause nausea, vomiting or severe diarrhea.
How to Use Elderberry for Influenza
The best way for most people to take elderberry is in a syrup form. The syrup that I recommend is Sambucol. Dosage is individualized based on age and severity of symptoms (whether it is used for prevention or treatment of influenza).
Start Sambucol within 12-24 hours of onset of symptoms for fastest results. It is unclear whether elderberry is safe in pregnancy. Discuss with your Naturopathic Doctor whether you should use elderberry during pregnancy and breastfeeding.
Other Treatments for Influenza
There are a number of natural treatments for influenza. Bed rest, warming socks, vitamin D, vitamin C, zinc, Echinacea, Ginseng, Andrographis, Astragalus, Goldenseal, Larch arabinogalactans, homeopathic belladonna and eupatorium, and other natural therapies all have been used successfully in the management of influenza symptoms and may be combined with Elderberry in certain situations.
The best advice if you are feeling the first signs of the flu (fever, aches, chills, fatigue, headache, coughing and sore throat)is to rest, take Elderberry and consult with a Naturopathic Doctor for individualized advice.
