Organic Elder Berry
Also known as: Sambucus nigra, Elderberry, Black Elderberry
Overview
Elderberry, derived from the *Sambucus nigra* plant, is a fruit traditionally used for its medicinal properties. It is rich in flavonoids, anthocyanins, and other bioactive compounds, giving it antioxidant, anti-inflammatory, and potential antiviral properties. Primarily, elderberry is used to prevent and treat viral respiratory illnesses such as the common cold and influenza. It is available in various forms, including extracts, capsules, and syrups. Research on elderberry is considered moderate, with several clinical trials and systematic reviews exploring its effects. While studies show promising results in reducing the duration and severity of upper respiratory symptoms, more research is needed to confirm long-term effects and optimal dosing. The available evidence is generally of moderate quality, indicating the need for further investigation to fully understand its benefits and safety.
Benefits
Elderberry supplementation has been shown to reduce the duration and severity of upper respiratory symptoms, particularly in the context of influenza and the common cold. A meta-analysis indicated a substantial reduction in symptom duration, with a large mean effect size. One systematic review found that elderberry may reduce the duration of influenza and could be associated with a lower risk of influenza complications and adverse events compared to oseltamivir. There is some evidence that elderberry has anti-inflammatory effects, although these may decline with ongoing supplementation. Elderberry supplementation has been found to be beneficial across various age groups, including adults and children, in reducing upper respiratory symptoms. Benefits are typically observed within the first few days of supplementation, with significant reductions in symptom duration and severity.
How it works
Elderberry's bioactive compounds, particularly flavonoids and anthocyanins, are believed to interact with viral particles and inhibit their replication. These compounds also have anti-inflammatory properties by modulating cytokine production. Elderberry extracts interact with the immune system by reducing the production of pro-inflammatory cytokines and may also have direct antiviral effects by binding to viral particles. Specifically, the flavonoids and anthocyanins in elderberry bind to and prevent the infection of cells by influenza viruses, such as H1N1. The bioavailability of elderberry's bioactive compounds can vary depending on the preparation and dosage form, but the extracts are generally well-absorbed and can exert their effects systemically.
Side effects
Elderberry is generally considered safe for use in treating viral respiratory illnesses, and there is no evidence that it overstimulates the immune system or leads to cytokine storms. However, mild gastrointestinal symptoms such as nausea, diarrhea, and stomach cramps have been reported in some studies. Allergic reactions, though rare, can occur in some individuals. There are no well-documented rare side effects associated with elderberry supplementation. Potential interactions with immunosuppressive drugs and other medications that affect the immune system exist, though specific interactions are not well-documented. Individuals with autoimmune diseases or those taking immunosuppressive medications should consult their healthcare provider before using elderberry supplements. Pregnant or breastfeeding women should use elderberry supplements with caution and under medical supervision due to limited data on safety in these populations.
Dosage
The minimum effective dose of elderberry is not well-established, but typical dosages range from 500 mg to 1000 mg per day of elderberry extract, standardized to contain a specific amount of anthocyanins or flavonoids. Optimal dosages are generally in the range of 500 mg to 1000 mg per day, taken 2-3 times a day at the onset of symptoms. There is no established maximum safe dose, but doses above 1000 mg per day are not typically studied or recommended. It is best taken at the onset of symptoms to maximize benefits. Capsules, syrups, or lozenges are common forms; the choice depends on individual preference and the specific formulation. Bioavailability can be enhanced by taking the supplement with food or in a form that is easily absorbed, such as a syrup or lozenge.
FAQs
Is elderberry safe?
Elderberry is generally safe and does not overstimulate the immune system, but it should be used under medical supervision in certain populations like pregnant or breastfeeding women.
When should I take elderberry?
It is best taken at the onset of symptoms to maximize benefits. It can be taken 2-3 times a day.
What results can I expect from taking elderberry?
You can expect a reduction in the duration and severity of upper respiratory symptoms, particularly in the context of influenza and the common cold.
Does elderberry cure viral infections?
Elderberry does not cure viral infections but can alleviate symptoms and reduce the duration of illness. It is not a substitute for medical treatment but can be used as a complementary therapy.
Research Sources
- https://pubmed.ncbi.nlm.nih.gov/33827515/ – This systematic review of 5 randomized trials (1187 records screened) found that elderberry may reduce the duration and severity of colds and influenza, but the evidence is uncertain. The review found no evidence of overstimulating the immune system or increasing cytokine storms, suggesting a safe profile for elderberry use.
- https://pubmed.ncbi.nlm.nih.gov/24409980/ – This meta-analysis of randomized, controlled clinical trials (180 participants) showed that elderberry supplementation substantially reduces upper respiratory symptoms, with a large mean effect size. The findings suggest that elderberry presents an alternative to antibiotic misuse and prescription drugs for routine cases of the common cold and influenza.
- https://pubmed.ncbi.nlm.nih.gov/30670267/ – This systematic review consolidates safety and efficacy data, including pharmacology, kinetics/dynamics, interactions, adverse effects, toxicology, and dosing. It supports the use of elderberry as a safe and potentially effective treatment for viral respiratory illnesses, providing a comprehensive overview of its properties.
