“Vaccinations are important,” but They Aren’t Enough – An Ancient Remedy May Be the Next Big Pill Against Coronaviruses, Colds, Flu and Meningitis – According to New Research

Nature’s Pharmacy just got a tech upgrade: ancient willow bark, long revered for its healing hug, might be the next big pill to pop against today’s viral pandemonium.

Viruses, ranging from the common cold to more severe illnesses, are a universal human challenge, and the search for effective, sustainable treatments is ongoing.

In a significant development, Finnish researchers have discovered that willow bark extract, known for its role in creating medicines like aspirin, exhibits potent antiviral properties in laboratory studies.

This natural extract has demonstrated effectiveness against a variety of viruses, including the enveloped coronaviruses responsible for colds and Covid-19, and the non-enveloped enteroviruses linked to diseases like flu and meningitis. The absence of current medications directly targeting enteroviruses makes this finding particularly promising.

“We need broadly acting and efficient tools to combat the virus load in our everyday life,” explains Professor Varpu Marjomäki from the University of Jyväskylä, the study’s lead researcher published in Frontiers in Microbiology. “Vaccinations are important, but they cannot deal with many of the newly emerging serotypes early enough to be effective on their own.”

The team had already established the extract’s efficacy against enteroviruses and has now broadened their investigation to include other viruses, aiming to decode how the extract works its antiviral magic.

To create the extract, willow bark is meticulously processed through freezing, grinding, and hot water extraction. This extract was then put to the test against various enterovirus strains and coronaviruses, showing that it could protect cells from infection without causing any harm to the cells themselves. Even when the Covid-19 virus penetrated the treated cells, it failed to replicate.

The study found differing mechanisms when combating various viruses. While it impeded the entry of enteroviruses into the cells, it seemed to disrupt the surface structure of coronaviruses, indicating that the extract operates through more than one antiviral pathway.

Further investigation into the willow bark extract revealed that among several tested compounds, only a specific salixin extract displayed antiviral activity, hinting at the complex interplay of multiple substances within the willow extract.

Although the precise chemicals responsible for this effect remain elusive, they are dedicated to isolating and identifying the active molecules, which may pave the way for groundbreaking antiviral drugs.

“We are presently continuing fractionations and bioactive molecule identification from willow bark extracts,” shares Marjomäki. “This will give us a number of identified pure molecules which we can study in further detail. Also, we will study a larger number of viruses with purified components. Purified components will give us better opportunities to study their mechanisms of action.”
