The elderberry extract used in the study is the result of technology developed by HerbalScience that enables the company to standardize the chemical profile of any selected botanical in order to deliver a compositionally and functionally consistent product that is effective and safe. The patented technology was developed for the company by top researchers in the areas of botanical and natural products chemistry and plant biology, as well as leading experts in supercritical CO2 and affinity absorbent extraction technologies, methods used for extracting plant phytochemicals.

The company's proprietary and environmentally-friendly technology is able to extract a broad diversity of phytochemicals from botanicals and produce a consistent and reliable chemical "fingerprint" for each and every dose. HerbalScience scientists also developed a process that enables the beneficial chemical compounds in botanicals to be enhanced while removing any harmful compounds like heavy metals and pesticides. With the application of this technology to elderberry, the company achieves a consistent chemical profile in its extract with batch-to-batch and dose-to-dose reliability, and maintains the natural synergy of the chemical make-up while optimizing the efficacy of its health benefits.
