Wild Plant Extracts Can Block Covid-19 Infection

A new study led by Emory University has found that two common wild plants can inhibit the activity of the virus causing Covid-19 to infect human cells. Laboratory experiments revealed that extracts from the flowers of tall goldenrod (Solidago altissima) and the rhizomes of the eagle fern (Pteridium aquilinum) efficiently stopped SARS-CoV-2 from entering human cells.

Since the active compounds are only present in small quantities in the plants, it would be ineffective – and even potentially dangerous – for people to attempt to treat themselves with them.

“It’s very early in the process, but we’re working to identify, isolate and scale up the molecules from the extracts that showed activity against the virus,” said study senior author Cassandra Quave, an associate professor of Dermatology and Human Health at Emory. “Once we have isolated the active ingredients, we plan to further test for their safety and for their long-range potential as medicines against Covid-19.”

By testing over 1,800 extracts and 18 compounds from the Quave Natural Product Library for activity against the new coronavirus, the scientists managed to identify the most promising candidates for potential treatments.

In a first step, they devised experiments with virus-like particles (VLPs) of SARS-CoV-2 and cells programmed to overexpress ACE2 (the receptor on which the coronavirus binds to infiltrate cells) on their surface. The analyses revealed a handful of extracts that stopped viral entry, with those from the tall goldenrod and the eagle fern exhibiting the strongest blocking activity.

Additional experiments using infectious SARS-CoV-2 virus instead of VLPs confirmed these results and showed that the protective power of the plant extracts worked in the case of four Covid variants: Alpha, Beta, Delta, and Gamma.

Further research is needed to determine the precise mechanism which enables these two extracts to block the virus from binding to the ACE2 receptor.

“We’ve shown that our natural products library is a powerful tool to help search for potential therapeutics for an emerging disease,” said study lead author Caitlin Risener, a doctoral student in Molecular and Systems Pharmacology at Emory. “Other researchers can adapt our screening method to search for other novel compounds within plants and fungi that may lead to new drugs to treat a range of pathogens.”

The study is published in the journal Nature Scientific Reports.

Does not matter how it works or if it works, FDA will not approve.

Infection or injection?

C’mon man, we all know the jab works so well, sheesh, no need for all these natural remedies.

In many cases the plant substances are highly toxic

Administering them is dosages high enough to be effective may do more harm than the original infection

Sounds a lot like ‘Forsythia’. /s

Seriously, though...I hope people are allowed to share their experiences somewhere without influence of our overlords.

Emory, eh?

Vikas P. Sukhatme, MD, ScD is the Dean of Emory Medical School. See here:
https://www.med.emory.edu/about/leadership/index.html

He co-wrote an article in the Times of India way back in May of 2021 (!!) advocating using Ivermectin against Covid, among other things. This got =ZERO= coverage in US media, including his hometown paper, the AJC, and his hometown news network, CNN.

Tell democrats that topically applying Toxicodendron radicans across the entire body is three times more effective than masking

May I direct your attention to sentence #2: “Since the active compounds are only present in small quantities in the plants, it would be ineffective – and even potentially dangerous – for people to attempt to treat themselves with them.”

Didn’t they claim the same dangers for ivermectin ? Can’t have people actually getting better without the help of big pharmaceutical companies!

They made absolutely outrageous claims about the dubious safety of both Hydroxychloroquine and Ivermectin. Both have been used for long periods (multiple decades) by tens of millions of people with no safety problems.

The FDA does not approve supplements.

“Consumer Reports” (Jan. 2023) had a review of supplements and it listed these supplements to always avoid. Many cause serious harm:

Chaparral (creasote bush, greasewood, Larrea divaricata, Larrea tridentata, larreastat): Kidney problems, liver damage.

Coltsfoot (coughwort, Farfarae folium leaf, foalswort, Tussilago farfara): Liver damage, possible carcinogen.

Comfrey (blackwort, bruisewort, slippery root, Symphytum officinale): Liver damage, cancer.

Germander (Teucrium chamaedrys, Teucrium viscidum): Liver damage, hepatitis.

Greater Celandine (celandine, Chelidonium majus): Liver damage.

Kava (ava pepper, kava kava, Piper methysticum): Liver damage, exacerbates Parkinson’s disease and depression, impairs driving.

Lobelia (asthma weed, Lobelia inflata,vomit wort, wild tobacco): nausea, vomiting, kiarrhea, tremors, rapid heartbeat, confusion, seizures, hypothermia, coma.

Pennyroyal Oil (Hedeoma puleggiodes, Mentha pulegium): Liver and kidney failure, nerve damage, convulsions.

Usnic Acid (beard moss, tree moss, usnea): Liver injury.

Yohimbe (Johimbi, Pausinystalia yohimbe, yohimbine, Corynanthe johimbi): raises blood pressure, causes rapid heart rate, headaches, seizures, liver and kidney problems, heart problems, panic attacks.
