Eastern White Pine Tree

A compound found in pine needles, called suramin, has been identified as a potential antidote to the current spike protein contagion resulting from the chimeric SARS-CoV-2 coronavirus, and the potential pathogenic transmission of the spike protein from the experimental mRNA vaccines.


Suramin can be naturally obtained as a tea from eastern white pine tree needles (Pinus Strobus). Among other beneficial constituents of eastern white pine tree needles are Alpha-Pinene, Beta-Pinene, Beta-Phellandrene, D-Limonene, Germacrene D, 3-Carene, Caryophyllene, vitamin A, and vitamin C. Eastern white pine needles also contain shikimic acid, the same molecule found in star anise herb used historically in Traditional Chinese Medicine to treat plagues and respiratory illness.


Pine needles have been used by indigenous populations around the world as both food and medicine for thousands of years. Fresh pine needles from eastern white pine trees and other appropriate trees have been used for centuries as sources of vitamin C and other phytochemicals that Native Americans used to treat respiratory infections and other ailments. Vitamin C is a known cure for scurvy, as scurvy is a disease of vitamin C deficiency. Pine needles contain many other substances that appear to reduce platelet aggregation in the blood, potentially preventing blood clots that lead to strokes, heart attacks, and pulmonary embolism diagnoses.


Suramin is strongly inhibitory to the replication of the coronavirus spike protein. It also has an inhibitory effect against components of the coagulation cascade and the inappropriate replication and modification of RNA and DNA. Excessive coagulation causes blood clots, mini-clots, strokes, and unusually heavy menstrual cycles, which are now being daily reported to VAERS post-vaccination. Recent research has shown it to be an in vitro inhibitor of SARS-CoV-2 infection in cell culture by preventing viral entry. Research shows this to be due to its potent inhibition of SARS-CoV-2 RNA-dependent RNA polymerase (RdRp), an essential viral lifecycle enzyme. It is proposed that suramin is 20 or more times as powerful as remdesivir, currently used as an anti-COVID-19 drug.1, 2, 3


Suramin is a polysulphonated naphthylurea with a potential antiviral, antiparasitic and antineoplastic activity that has been widely used in the clinical treatment of parasites and viral infections. It has also been used in the treatment of trypanosomiasis (sleeping sickness) and onchocerciasis since the early 1920s. Particularly, it is effective to treat African sleeping sickness caused by Trypanosoma brucei rhodesiense and Trypanosoma brucei gambiense without affecting the central nervous system. It is usually administered by intravenous injection. The mechanism of action of suramin is unclear, but parasites are thought to be able to selectively take suramin through receptor-mediated endocytosis of a drug that is bound to low-density lipoproteins and, to a lesser extent, other serum proteins. Once found inside parasites, suramin combines with proteins, especially trypanosomal glycolytic enzymes, to inhibit energy metabolism. It is also used in the treatment of river blindness or Onchocerciasis, a disease caused by infection with the parasitic worm Onchocerca volvulus. Symptoms include severe itching, bumps under the skin, and blindness. It is the second-most common cause of blindness due to infection, after trachoma.


Suramin has also been shown to be an inhibitor against a wide variety of other viruses, including Zika and Chikungunya viruses, indicating its diverse mechanisms of action against multiple viruses.4, 5, 6, 7, 8, 9, 10 Zika virus is a mosquito-borne flavivirus that mostly causes asymptomatic infections or mild disease characterized by low-grade fever, rash, conjunctivitis, and malaise. Chikungunya virus is a mosquito-transmitted alphavirus that can cause a debilitating disease that is primarily characterized by persistent joint pain.

Suramin

History

Suramin was first produced by chemists Oskar Dressel, Richard Kothe, and Bernhard Heymann in the laboratories of Bayer AG in Elberfeld after research into several urea-like compounds. Bayer still sells the drug under the Germanin brand. The chemical structure of suramin was kept secret by Bayer for commercial and strategic reasons but was clarified and published in 1924 by Ernest Fourneau and his team at the Pasteur Institute.


Mechanism Identified Whereby Suramin Inhibits SARS-CoV-2 RdRp


Thus, research shows that suramin is a direct and potent viral RdRp inhibitor by direct inhibition, with structural analysis showing the mechanism of binding and inhibition. This is the first non-nucleotide inhibitor of the SARS-CoV-2 RdRp, and this indicates the potential to develop suramin analogs and drug formulations as potent and effective inhibitors of viral replication.

Comparing the RdRp-suramin complex to the remdesivir-bound RdRp complex shows that the two suramin molecules occupy specific positions on the RNA strand and the primer strand, blocking the binding of the duplex RNA template-primer strand to the active site of the enzyme. Simultaneously it prevented the entry of nucleotide triphosphate into the catalytic site. This directly blocked RdRp catalytic activity.11


Suramin and Cancer Therapy


Not only has suramin from pine needles been used traditionally for viruses and parasites, but suramin-based drugs have been extensively tested as a treatment for several types of cancers..12, 13, 14, 15, 16, 17 Technically, as an anti-cancerous compound suramin blocks the binding of various growth factors, including insulin-like growth factor I (IGF-I), epidermal growth factor (EGF), platelet-derived growth factor (PDGF), and tumor growth factor-beta (TGF-beta), to their receptors, thereby inhibiting endothelial cell proliferation and migration. This agent also inhibits vascular endothelial growth factor (VEGF)- and basic fibroblast growth factor (bFGF)-induced angiogenesis; retroviral reverse transcriptase; uncoupling of G-proteins from receptors; topoisomerases; cellular folate transport; and steroidogenesis.18, 19, 20, 21, 22


The inhibitory effect of suramin from pine needles on the coronavirus spike protein, Zika and Chikungunya viruses, and certain parasites warrant further evaluation of this naturally occurring compound as a potential broad-spectrum therapeutic

Preparing Pine Needle Tea

Making pine needle tea is easy, and only requires fresh, young pine needles and hot water. However, it is imperative to choose the right pine needles as there are 20 known toxic varieties of pine trees. The Eastern White Pine (Pinus strobus) is nontoxic and an excellent variety. Avoid using these toxic varieties: Ponderosa Pine, Balsam Fir, Lodgepole, and Monterey Pines. Additionally, there are also quite a few trees that are commonly called “pine trees”, but are in fact toxic imitators, such as the English Yew, Norfolk Island pine, and the Yew pine. These should never be used to brew pine needle tea. Again, most experts recommend using Eastern White Pine to brew tea.


Ingredients:

1 cup water filtered

1 handful fresh eastern white pine needles


Instructions:


· To begin, collect or purchase fresh pine needles. A small handful should be sufficient for a strong cup of tea.

· Cut off any of the brown ends or sheaths of the needles - they can also just be pulled off. Chop the needles into 1/4 inch chunks

· Bring a pot of water to boil, and then add in the freshly cut pine needles.

· Cover the pot with a lid and allow the needles to steep for 3-4 minutes.

· Remove the pot from heat, but keep it covered and allow it to continue steeping.

· Once all the needles have sunk to the bottom and the tea has cooled, pour through a strainer into a cup and enjoy!
