Elderberry
Specifically for Whooping Cough
0 up • 0 down
Why it works for Whooping Cough:
Elderberry has some supportive and fairly consistent data for shortening symptoms of viral upper-respiratory infections (common cold / influenza) when started early, but pertussis is a bacterial infection (Bordetella pertussis) for which recommended therapy is antibiotics and medical care — not elderberry.
- Antioxidant / anti-inflammatory compounds. Elderberries are rich in anthocyanins and other polyphenols that have antioxidant and anti-inflammatory effects in lab studies; these properties are one reason investigators study elderberry for respiratory symptoms. MDPI
- Antiviral activity in vitro. Extracts of Sambucus nigra have shown inhibition of influenza viruses in laboratory (in-vitro) studies and animal models. This is why most clinical trials have tested elderberry against influenza / cold viruses. ScienceDirect
- Immune-modulating effects. Some ex-vivo and small human studies show elderberry can alter cytokine production (for example TNF-α and other markers), which could plausibly reduce symptom severity in viral infections — but immune modulation is complex and not equivalent to killing bacteria. BioMed Central
Important clinical point: pertussis (whooping cough) is caused by the bacterium Bordetella pertussis. Elderberry’s data are mostly about viruses (cold, influenza). There are no clinical trials or authoritative studies showing elderberry cures or treats pertussis — so you should not rely on elderberry instead of standard medical antibiotic treatment. CDC
How to use for Whooping Cough:
Because there is no clinical evidence for pertussis, there are no evidence-based elderberry instructions specifically for whooping cough. Below are the dosing regimens that have been used in human clinical trials for viral upper-respiratory infections (useful for comparison):
- Syrup (common clinical trial regimen): 15 mL (≈1 tablespoon) of elderberry syrup, 4 times daily, usually for 3–5 days, when started within 48 hours of symptom onset. This is the regimen used in several randomized trials (for influenza-like illness / influenza). SAGE Journals
- Lozenges / extract forms: Some trials used lozenges containing ~175 mg elderberry extract taken 4 times daily for short courses. Other trials report liquid dosages equivalent to several grams of fruit juice per dose (check product labels and trial details). RxList
- Timing: Most trials that showed benefit started elderberry within 48 hours of symptom onset; earlier start was associated with better outcomes for viral illness. ScienceDirect
If someone chooses to use elderberry as a supportive measure for viral coughs (not for pertussis), use commercially prepared, cooked/processed elderberry products and follow the product label / clinical-trial style dosing (eg. 15 mL 4×/day), and tell your clinician. There is no approved standard dose for treating pertussis because there are no trials. Drugs.com
Scientific Evidence for Whooping Cough:
Evidence that exists (viral respiratory infections):
- Randomized trials (small) showing elderberry syrup reduced duration/severity of influenza-like illness and common cold symptoms (examples: Zakay-Rones et al. and later trials). Typical positive trials used 15 mL four times daily and reported shorter symptom duration. sambucol-phiz.com
- Systematic review (BMC Complementary Medicine and Therapies, 2021) — review of 5 randomized trials: elderberry may reduce duration/severity of colds and influenza, but evidence quality is limited and uncertain. BioMed Central
- Meta-analyses / reviews and regulatory monographs (EMA assessment, Nutrients, MDPI review) summarize in-vitro antiviral activity and limited clinical benefits for viral URIs when started early. ScienceDirect
- Recent clinical trials (emergency department and outpatient influenza trials) looked at elderberry extracts for influenza and reported mixed but sometimes favorable results when used early. SpringerLink
What is not found in the literature:
- No credible clinical trials or systematic reviews show elderberry is effective against pertussis (whooping cough) caused by Bordetella pertussis. I could not find randomized trials, observational data, or authoritative guidance recommending elderberry for pertussis. If you search the elderberry literature you find viral studies — not bacterial pertussis trials. That means there is no proof elderberry treats whooping cough. BioMed Central
Specific Warnings for Whooping Cough:
Whooping cough is bacterial — see CDC: treat with antibiotics and get medical care. Delay in appropriate antibiotic therapy for pertussis can lead to serious complications (especially in infants). Elderberry is not an alternative. CDC
Raw/unprocessed elderberries, leaves, stems can be toxic. Many elderberry species (and plant parts) contain cyanogenic glycosides that can release cyanide if eaten raw; there are documented poisonings from improperly prepared elderberry products. Always use commercially processed or properly cooked preparations. Guidance from university extension services and agricultural safety documents warns to cook before consuming. OSU Extension Service
Potential immune effects — caution in autoimmune / immunocompromised patients. Elderberry can modulate cytokines; theoretical concerns exist that it could interact with autoimmune conditions or immunosuppressive treatments. While evidence is limited, many reviewers recommend caution and clinician input for people with autoimmune disease, those on immune-suppressing drugs, and pregnant/breastfeeding people. BioMed Central
Pregnancy and breastfeeding: Safety data are insufficient; many authorities advise avoiding elderberry supplements in pregnancy/lactation unless a clinician approves. EatingWell
Drug interactions / other cautions: Not many well-documented drug interactions, but because of immune effects and variable supplement quality, check with a clinician or pharmacist if on chronic medications (especially immunosuppressants). Also avoid giving concentrated elderberry products to infants under 1 year unless directed by pediatrician. RxList
Product quality / labeling: Supplements are not standardized like prescription drugs. Use reputable brands, third-party tested products, and follow label dosing. Clinical trials used specific standardized products and dosing; homemade raw syrup may be unsafe. Drugs.com
General Information (All Ailments)
What It Is
Elderberry refers to the dark purple berries of the Sambucus nigra plant, also known as the European elder or black elder. These berries have been used for centuries in traditional medicine, especially in Europe and North America, for their potential immune-boosting and antiviral properties. The most common form used in health products comes from the ripe berries, though the flowers are also used for teas and syrups. Elderberry is commonly available as syrups, lozenges, gummies, capsules, and teas.
The raw berries, bark, and leaves of the elder plant are toxic when unripe, as they contain cyanogenic glycosides — compounds that can release cyanide. However, properly cooked or processed elderberries are safe to consume and rich in beneficial compounds such as anthocyanins, flavonoids, and vitamin C.
How It Works
Elderberry’s health effects are primarily attributed to its bioactive compounds, especially anthocyanins, which are potent antioxidants. These compounds help neutralize free radicals — unstable molecules that can damage cells and contribute to inflammation and disease.
In terms of immune function, elderberry appears to support the body’s natural defenses by:
- Enhancing immune response: Certain studies suggest elderberry can increase the production of cytokines, which are signaling molecules that regulate immune activity.
- Antiviral effects: Laboratory research has shown that elderberry extracts may inhibit the replication of certain viruses, including influenza strains. The compounds seem to prevent viruses from binding to and entering host cells, potentially shortening the duration and severity of symptoms.
- Anti-inflammatory action: The flavonoids in elderberry may reduce inflammation, which is beneficial during infections when inflammation can contribute to discomfort and fatigue.
While these mechanisms are supported by some scientific studies, results vary, and more rigorous clinical research is still needed.
Why It’s Important
Elderberry has gained popularity as a natural remedy for colds and flu. Its importance lies in its potential to:
- Shorten the duration of respiratory infections: Some clinical trials have reported that elderberry extract can reduce the length and severity of cold and flu symptoms when taken early.
- Provide antioxidant protection: The high levels of anthocyanins and vitamin C help combat oxidative stress, supporting overall cellular health and resilience.
- Offer a plant-based immune supplement: For those seeking natural alternatives to synthetic medications, elderberry is an appealing option due to its long history of traditional use and relatively mild side effect profile when prepared properly.
Beyond immunity, elderberry may also contribute to heart and metabolic health due to its anti-inflammatory and antioxidant effects, though more evidence is needed in these areas.
Considerations
While elderberry can be beneficial, there are important points to consider:
- Raw berries are toxic: Unripe or uncooked elderberries contain cyanogenic compounds that can cause nausea, vomiting, and diarrhea. Only properly prepared or commercial products should be used.
- Quality varies: Supplements are not tightly regulated, so product potency and purity can differ widely. Look for standardized extracts from reputable brands.
- Possible interactions: Elderberry may interact with immune-suppressing medications (e.g., for autoimmune conditions or organ transplants), as well as with certain diabetes or diuretic drugs.
- Pregnancy and children: There’s limited safety data for use during pregnancy or in young children, so caution is advised.
- Evidence limitations: Although some studies show promising results, the overall body of scientific evidence remains moderate, and elderberry should not replace conventional medical treatment for serious infections.
