Elderberry: Health Benefits and Risks

This post was written with Consensus AI Academic Search Engine – please read our Disclaimer at the end of this article. Elderberry (Sambucus nigra L.) has been used for centuries in traditional medicine for its purported health benefits. Recent scientific studies have explored its potential effects on cardiovascular health, respiratory infections, metabolic functions, and more. This article reviews the health benefits and risks associated with elderberry consumption based on current research.

Cardiovascular Health

Elderberry is rich in anthocyanins, which are believed to have cardio-protective properties. However, studies have shown mixed results regarding its efficacy. A 12-week study involving postmenopausal women found that chronic consumption of 500 mg/day of elderberry extract did not significantly alter biomarkers of cardiovascular disease (CVD) risk, although it was deemed safe1 3. Another study indicated that elderberry juice had a minor effect on serum lipids and antioxidative capacity, suggesting that higher doses might be needed to observe significant benefits2.

Respiratory Health

Elderberry has been traditionally used to combat respiratory infections, and some studies support its efficacy. A clinical trial involving air travelers found that elderberry supplementation significantly reduced the duration and severity of cold episodes5. Another study on elderly subjects showed that a combination of elderberry and reishi extracts reduced the duration and severity of respiratory tract infections8. However, a study on influenza patients found no significant difference in the duration or severity of symptoms between the elderberry and placebo groups, contradicting previous findings4.

Metabolic Health

Elderberry may also influence metabolic health. A pilot study found that elderberry juice increased carbohydrate oxidation after a meal tolerance test, although it did not affect insulin sensitivity or glucose tolerance6. This suggests potential benefits for metabolic function, but more research is needed to confirm these findings.

Cognitive Function

A study on older adults consuming a mixed berry beverage, including elderberry, showed improvements in cognitive performance, particularly in working memory. The beverage also reduced total and LDL cholesterol levels, indicating potential benefits for both cognitive and cardiovascular health9.

Safety and Tolerability

Elderberry is generally considered safe for consumption. A study on mice found that elderberry extract had a favorable toxicological profile and could be a healthier alternative to synthetic colorants7. Human studies also reported good tolerability, with no significant adverse effects observed1 6.

Conclusion

Elderberry shows promise in various health domains, including cardiovascular, respiratory, metabolic, and cognitive health. While it is generally safe for consumption, the efficacy of elderberry in altering specific health biomarkers remains inconclusive and warrants further research. Higher doses and longer study durations may be necessary to fully understand its potential benefits.
