Beat Flu Season with this Powerful Herb

Elderberries are dark violet, almost black-appearing stone fruits that grow in clusters in temperate to subtropical regions of the earth. Their rich color is due to anthocyanins—a class of phenolic compounds. Among flavonoids, anthocyanins are highly concentrated in elderberries and are thought to be the active constituents of the fruit (Mikulic-Petkovsek et al., 2015). Elderberries also contain a host of vitamins (A, B1, B2, B6, B9, C, and E), minerals (potassium, calcium, and magnesium), trace elements (copper, zinc, and iron), and phytochemicals (carotenoids, phytosterols, and polyphenols) (Tiralongo, Wee, & Lea, 2016).

In a randomized, double-blind, placebo-controlled clinical trial, Tiralongo and colleagues (2016) investigated whether or not a standardized elderberry extract could provide beneficial effects on respiratory and mental health. 

In this study, black elderberry (Sambucus nigra L.; Haschberg variety from the Steiermark region in Austria) was chosen because it was previously found to demonstrate antimicrobial activity against human respiratory pathogens (gram-positive bacteria of Streptococcus pyogenes, groups C and G Streptococci, and gram-negative bacterium Branhamella catarrhalis), and be an inhibitor of the propagation of human pathogenic influenza viruses (Krawitz et al., 2011). 

The exact extract was produced by Iprona AG, Lana (BZ), Italy (under the brand name BerryPharma), and contained 300mg of elderberry extract:  22% polyphenols (quercetin and its glycosides, rutin), 15% anthocyanins (cyanidin and pelargonidin glycosides), 150mg of rice flour, and several mineral, trace elements, and vitamins. Further research is needed to assess the range of elderberry's effect on cold duration and severity and mental health proposed benefits.

One of the distinctions of the Tiralongo et al. study that conducted an RCT of a standardized, proprietary preparation of elderberry is that the researchers took the time not only to standardize the dose (300mg of elderberry per dose) but also to standardize the polyphenol and anthocyanin content (22% and 15%, respectively). 

This does not necessarily mean that a different preparation of 300mg of elderberry extract does not contain anthocyanins and polyphenols or would not be as effective, but it does suggest that using the proprietary product would give the consumer a lab-verified and researched dose of anthocyanins and polyphenols that was shown to have a documented, statistically significant clinical effect.

Treatment with elderberry fruit extracts is very well-tolerated. No adverse events related to elderberry have been reported in clinical trials in children or adults using specific extracts, including BerryPharma, Iprona AG, Sambucol, Nature's Way, and ViraBLOC, Herbal Science. (Zakay-Rones et al., 1995; Zakay-Rones, Thom, Wollan, & Wadstein, 2004; Kong, 2009; Tiralongo, Wee, & Lea, 2016).

Many people cannot afford to take time off work, even when they are sick, so being able to use elderberry can be beneficial for them.
