Coronavirus: SARS-CoV2 Virus and COVID-19 Disease

By Cat, March 2020 and ongoing

This article has been moved from its original home: Notes on Natural Health Topics, A – C.

The coronavirus known as SARS-CoV-2 and related disease COVID-19 that started in Wuhan, China in December 2019 is now affecting people around the globe. As I learn more about this virus and the disease it causes, I will add notes and references here. 

As I’ve learned more about COVID vaccines, I’ve moved the “Vaccines” section to a separate article: Coronavirus: Notes on Vaccines for COVID-19

  • Includes: 1. General Info on Coronaviruses; 2. Is COVID-19 Made in a Lab? 3. Effect of Social Distancing, Isolation; 4. Factors Affecting Risk of Getting COVID-19 and Related Diseases; 5. Prevention & Treatment of COVID-19 (Conventional Medicine); 6. Prevention & Treatment of COVID-19 (Natural Medicine)

General info on coronaviruses

The common cold*, influenza (respiratory flu), SARS, MERS, and COVID-19 are all caused by coronaviruses.  All incubate in the sinuses before moving down the respiratory tract to settle in the lungs. The SARS-CoV2 is a variation of the original SARS virus, and is the cause of COVID-19 disease that started in Wuhan China, and is now spreading around the globe. See a 4½ minute YouTube video about the two types of SARS-CoV2 (L- and S-Types) that cause COVID-19 (3a).

‘* NOTE: some varieties of the common cold are caused by other viruses such as rhinovirus.

One way to treat coronavirus early-on is to use a Neti pot to clean the sinuses; see my article on Ancient Remedies for Every Home, which includes instructions for using a Neti pot.

COVID Origin: Is it Made in a Lab?

Ever since I heard a news item on CBS news back in 2020, that researchers found a COVID-19 DNA segment that duplicates an HIV DNA segment (HIV is AIDS). While I believe it was intentionally engineered as a bio-weapon, this is still an open, unresolved topic. While there’s plenty of proof it was made in a lab, the intent of that experiment is still unknown/unproven.

See Mercola articles [NOTE: He closes down articles after 48 hours; however, some of his articles may be copied on other sites; I recommend searching for the article title…

Here’s his Story at a Glance (COVID-A Bio Warfare Weapon?):

    • Francis Boyle, who drafted the Biological Weapons Anti-Terrorism Act of 1989, believes COVID-19 is a weaponized pathogen that escaped from Wuhan City’s Biosafety Level (BSL) 4 facility
    • A Lancet paper published by physicians who treated some of the first COVID-19 patients in China showed that patient zero, the one believed to have started the transmission, was nowhere near the Wuhan seafood market. What’s more, there were no bats sold in or even close to the market
    • SARS-CoV-2 appears to be a benign bat coronavirus modified to integrate spike proteins that allows the virus to enter human cells by attaching to ACE-2 receptors
    • The virus also appears to have been modified to integrate an envelope protein from HIV called GP141, which tends to impair the immune system. A third modification appears to involve nanotechnology, which allows the virus to remain airborne longer


BA.5 Variant

See Mercola:; saved: Health-Nutrition / Podcasts-Articles / Mercola / COVID > COVID-BA.5_KingOfVariants_072122.pdf. Here’s his Story At-A-Glance:

    • Rapid mutation of the SARS-CoV-2 virus was expected and predicted, as vaccinating against any highly mutable virus, such as the coronavirus, pressures the virus to adapt. Omicron initially arose in “fully vaccinated” patients, raising suspicions that the mass vaccination campaign itself was driving the rapid mutation of the virus
    • One of the latest variants, BA.5 — now believed to be the cause of nearly all COVID infections — is tied with (and may even surpass) measles in terms of its infectiousness and transmissibility. That makes it the most infectious of all SARS-CoV-2 variants, and one of the most infectious viruses known to man
    • Fortunately, it’s also considerably less deadly than the original Wuhan strain
    • Even if you’ve had COVID before, got the jab and all your boosters, and even if you have hybrid immunity (meaning you’ve had both past infection and the COVID jab), chances are you’ll probably catch BA.5, as it seems particularly adept at circumventing all previous defenses
    • The likelihood of reinfection is the fodder fearmongerers needed to reignite calls for COVID restrictions such as lockdowns and stripping people of their inherent rights and freedoms, and, of course, more boosters

Effect of Social Distancing/Isolation

Our government bodies and many health practitioners are recommending social distancing and even social isolation, to keep the disease from spreading and reduce your risk of getting it from others, or giving it to others. But such behavior can also increase mortality (not necessarily caused by exposure to the disease, but rather by depression and other issues that result from avoiding social interaction). See an interesting article on Green Med Info: 13 [Scientific] Studies Reveal How Scoial Distancing (i.e. Social Isolation) Can Increase Mortality (2a).

Factors Affecting Risk of Getting COVID-19 and Related Diseases

Nutrients to Improve your Immunity to COVID

hmm, not sure what happened to this text. Hmm, although I lost the original text, I can add new text as follows.

Importance of Fermented Foods, Consumed Daily

If you are not familiar with fermented foods (different from “pickled” foods), check out my Curing, Culturing, Fermentation & Tonics Menu, and my article: Pickling and Lacto-Fermentation (About) 

From Mercola: Fermented Foods May Lower Risk of Death, especially to COVID. I’ve saved a pdf version of his article at HEALTH-NUTRITION / 2-PODCASTS-ARTICLES / MERCOLA > FermentedFoods-MayLowerRisk-Death_122321.pdf.

    • “Countries that consume higher amounts of traditionally fermented foods have lower COVID-19 mortality rates. According to German researchers, significant changes in the microbiome caused by modern life and low fermented food consumption may have increased the spread or severity of the disease
    • For each gram-per-day increase in the average national consumption of fermented vegetables, the mortality risk for COVID-19 decreased by 35.4%”

Fermented foods may also be helpful against depression and anxiety:

    • “A review of seven small clinical trials found probiotics and/or prebiotics may be helpful for those struggling with depression and anxiety
    • Two types of gut bacteria in particular, Coprococcus and Dialister bacteria, have been shown to be “consistently depleted” in individuals diagnosed with clinical depression
    • Gut bacteria associated with good mental health synthesize the dopamine metabolite 3,4-dihydroxyphenylacetic acid, while those associated with depression produce γ-aminobutyric acid.”

I love fermented fruits, such as blueberries mixed with orange (including the pith) and pecans; see my recipe: Fermented Blueberries, Raspberries, Blackberries or Fermented Orange or Other Citrus. I eat a spoonful every morning with breakfast (or I add it to my smoothie), or with dinner.

I also add Mercola’s fermented greens and fermented beet powders to my daily smoothie.

Glutathione Deficiency May Be Associated with COVID Severity

This topic got my attention because for a very long time, I had glutathione deficiency, primarily because I had trouble with sulfur containing foods such as the onion family, and with certain supplement substances like N-Acetyl Cysteine (NAC), Alpha Lipoic Acid (ALA), and glutathione because sulfur is part of those molecules. Fortunately, my naturopath recommended I take myo-inositol to help with my insulin resistance, and my acupuncturist who practices NAET (to resolve allergies and food sensitivities); these together resolved my sulfur issues in 20181-2019, and so far, even at the age of 71, I’ve not succumbed to COVID.

See also the Topic “Insulin Resistance” below.

The following is from Mercola’s article:

From the article’s summary notes:

    • “A glutathione deficiency may be at the root of severe illness, as it leads to significant oxidative stress, lung inflammation and multiorgan failure with COVID
    • One scientist linked glutathione deficiency with many of the comorbid conditions that raise COVID-19 severity, including age, diabetes, gender and smoking
    • The researcher also found data indicating that glutathione deficiency can impact your ability to synthesize vitamin D, another risk factor for severe disease
    • NAC supplementation, foods rich in glutathione precursors, aerobic exercise and strength training can help support healthy levels.”

“Foods that have had a positive impact on glutathione production include cruciferous vegetables such as broccoli, green tea, curcumin, rosemary and milk thistle.36 Getting quality sleep may also help.

Different types of exercise* can influence your levels. In one study researchers enrolled 80 healthy but sedentary volunteers to measure the type of exercise that may have the greatest effect.39 They found that aerobic training in combination with circuit weight training showed the greatest benefit.” [* see]

Insulin Resistance and Keto

from Mercola: Here’s quote of his “story at a glance” (bolding the text is added by me)

  • Your metabolic health has a significant impact on COVID-19 severity, and at least 9 in 10 Americans are metabolically unhealthy
  • One of the classic changes associated with insulin resistance, obesity and metabolic syndrome is overactivation of the innate immune system, with decreasing activity in the adaptive immune system
  • When it comes to healthy aging, it’s not your biological age that matters but, rather, your immune and metabolic age, both of which are malleable and can be improved through simple lifestyle changes
  • Research shows that when blood sugar is well-controlled and there’s less glycemic variability, people do better when contracting COVID-19. When they have high levels of glycemic variability, which is indicative of insulin resistance, they fare much worse

Mercola also discusses (in a separate article: “Ketones, the Fourth Fuel” (1L)) how going keto (following a ketogenic eating plan) can reduce your risk of getting COVID-19 by avoiding insulin resistance.

I have insulin resistance, but when I started taking myo-inositol supplement in 2018 (at the advice and guidance of my naturopath), my insulin resistance minimized so that I lost 30 pounds in 2 months, and have maintained that.  I highly recommend taking this supplement. My ND recommended starting with 1/16 tsp daily, and slowly increasing to ¼ tsp daily; this is less than the cited dosage on the supplement container. I tried increasing to ½ tsp daily and then to 1 tsp daily, but these increases had no added effect, so I returned to ¼ tsp daily.

For more about myo-inositol and insulin resistance, see my post: Choline, Inositol, and Insulin Resistance.

Blood Type 

from Mercola: See his article for references.

The results from three studies show that blood type O has some protective effect against COVID-19; one scientist believes the factor is small compared to comorbidities”

“23andMe released preliminary results from a study they conducted using the information of more than 750,000 people.7 Their early results suggest that a person’s blood type has an influence on their susceptibility to the virus.” … “[They] reported that the percentage who tested positive for COVID-19 by blood type was 4.1% for blood group AB.10 The differences reported in the study showed that those with type O had a 9% or 18% lower potential for testing positive for the virus when compared to those with blood types A, B or AB.”

Similar conclusions were made by at least two other studies: one in China, one in Spain and Italy.

Mercola also states that blood type is not the most important factor; instead, “optimize your vitamin D level, improve your metabolic sensitivity and reduce insulin resistance with intermittent fasting.

Prevention and Treatment of COVID-19 (Conventional Medicine)

This section includes reasons why I don’t recommend these recommendations. NOTE: Each method is listed in alphabetic order.



A Mercola article (1q) recommends this drug for treatment of COVID infection; however it is controversial. It has a long history of use as an antiparasitic, but its antiviral properties have been under investigation since 2012.

Povidone iodine (PVP-I)

From Mercola (1s); see also Dr Peter McCullough’s article: Povidone Iodine, Oran and Nasal Hygiene (Jan 2022) (13)

“A simple mouth/nose spray containing povidone iodine (PVP-I) could act as an effective shield to protect against COVID-19. PVP-I is a microbicidal agent with a virucidal efficacy of 99.99%. When applied, [it] acts as a protective layer, coating the nasal and oral mucosa, which helps prevent SARS-CoV-2 from binding with ACE2 receptors and gaining entry into your cells. … Povidone iodine solutions have been found to inactivate SARS-CoV-2 in as little as 15 seconds and potentially reduce the carriage of infectious SARS-CoV-2 in people with mild to moderate COVID-19.

Hydrogen Peroxide (H2O2)

From Mercola: Hydrogen PeroxidePrevents COVID-19. He closes down his articles after 48 hours, so I saved a pdf copy: HEALTH-NUTRITION / PODCASTS-ARTICLES / MERCOLA > COVID-HospitalStudy-H2O2-CanPreventInfection_072322.pdf. If you’d like a copy, see my  “About” page to contact me. Here’s Mercola’s Story at a Glance:

    • “A hospital study published in June 2022 revealed that hydrogen peroxide (H2O2) mouthwash, gargle and nasal rinse protected against COVID-19 better than the jab
    • When food grade H2O2 is nebulized for approximately 30 minutes in normal saline it also reaches your sinuses and lungs where it can kill the virus, augment your natural defense system and may help stop an ongoing infection in the lungs and upper respiratory tract
    • Taxpayers recently spent $275 million, or $1,833 per dose, on a new monoclonal antibody drug. It is approved for people who are most vulnerable and at high risk for progression to severe disease despite the risks not being known at this time
    • Paxlovid is another drug purchased with taxpayer dollars at up to $530 per five-day course of treatment. People are requiring a second course of treatment when the infection rebounds with worse symptoms, as it did with quadruple-vaccinated Dr. Anthony Fauci
    • Although health authorities would like to keep you chained to new and not thoroughly tested drugs, you have choices including highly successful protocols that cost less and use supplements and drugs that have been sold for many years”

For instructions on how to nebulize H2O2, see: Get Better Wellness article: How to Nebulize H2O2


From Mercola (1r):

Zinc and Selenium deficiency leads to worse COVID outcomes. these deficiencies are not uncommon and may be prevalent in those with co-morbidities linked to worse COVUD outcomes. Protect your health and wellness with adequate levels of zinc and selenium.

Cat’s notes (See also Minerals (About) for more):

  • It is important to have proper balance of zinc and copper (8:1 per Weston a Price Foundation, so I would add copper to the list.
  • Selenium must be in chelated form, such as “selenomethionine,” rather than salt form such as sodium selenite, which is a toxic heavy metal.

Monoclonal Antibodies

I’m not familiar with this option, but learned about it in an email from Medicare so I thought I’d share it. Its about this treatment for people with high-risk COVID-19-positive patients. See “Combat COVID”for more info (9).

Vaccines for COVID

Moved to its own article: Coronavirus: Notes on Vaccines for COVID-19 

Ventilators and Other Options:

You may have heard that some patients do not do well on ventilators; the following is a quote from Dr. Mercola’s 5/6/20 email newsletter: “A number of published papers have noted ventilators make COVID-19 death risks soar. One report suggests the comparison was 76.4% vs. 19.8% (18-65) and 97.2% vs. 26.6% (65+). Should we be doing this instead?

From Mercola (1g); the following are his summary notes for the article:

    • “COVID-19 patients who are put on ventilators have an increased risk of death. It may turn out that ventilators are inappropriate for a majority of patients.
    • Doctors at UChicago Medicine report “truly remarkable” results using high-flow nasal cannulas (HFNC) in lieu of ventilators. Of 24 COVID-19 patients who were in respiratory distress, only one required intubation after 10 days of HFNC.
    • A more complicated treatment strategy that’s showing promise is membrane oxygenation (ECMO), in which the patient’s blood is oxygenated outside the body before pumped back into circulation. ECMO is recommended for relatively young patients with few comorbidities who fail to respond to ventilator treatment.
    • Mechanical ventilation can easily damage the lungs as it’s pushing air into the lungs with force. Hyperbaric oxygen treatment (HBOT) may be a better alternative, as it allows your body to absorb a higher percentage of oxygen without forcing air into the lungs.
    • Chinese doctors report “promising results” after treating five COVID-19 patients with HBOT and NYU Langone Health is currently recruiting COVID-19 patients for a study comparing HBOT to standard of care alone.”

From Mercola (1h)

Lying in the prone (face down) position, in which your chest is down and your back is up, could be a simple way to improve outcomes in cases of severe respiratory distress. This topic has received renewed attention during the COVID-19 pandemic, as invasive mechanical ventilation is conventionally delivered with the patient in the supine (face up) position, which refers to lying on your back.

This seems counter intuitive, as it must be more difficult for the lungs to expand when you lay face-down. However, from the article: “In [Acute Respiratory Distress Syndrome], the lung’s air sacs, or alveoli, become damaged. Fluid leaks through the air sacs’ damaged walls and collects.11 Fluid in the lung will increase its weight, which then squeezes out the gas from the dependent regions. If the sponge represents a fluid-filled lung, in the supine position the dependent regions are at the back of the lung.

See a 10 min YouTube video: for more about the prone position.

Prevention and Treatment of COVID-19 (Natural Medicine)

NOTE: Each method is listed in alphabetic order, except Vitamins are first.

Check out an eBook, Stealth Strategies to Stop COVID Cold, by several authors including Mercola on In the introduction, it states, “The information in this document is a summary of a more comprehensive review of vitamin D and COVID-19 for health professionals. It can be downloaded for free at” (I’ve saved the downloaded pdf on HEALTH-NUTRITION / PODCASTS-ARTICLES / EBOOKS >  CovidStopCold_fm Mercola.pdf).

Herbal Remedies for Treating Coronavirus Disease

From Mercola: article (2/5/22): Sweet Wormwood Again Shows Effectiveness Against COVID-19. Sadly Mercola pulls his articles from the web after 48 hours, so I’ve saved this article as a pdf (saved HEALTH-NUTRITION / PODCASTS-ARTICLES / MERCOLA ARTICLES > COVID-HerbalRemedy_SweetWormwood_020522.pdf).



      • Sweet wormwood (Artemisia annua) is a traditional plant-based medicine with antiparasitic, antiviral and anticancer properties. Studies show it’s also an effective remedy in the treatment of mild to moderate COVID-19
      • In April 2020, China added three Traditional Chinese Medicine (TCM) formulas to its standard of care for COVID-19, including one containing sweet wormwood, called Jinhua Qinggan
      • In one COVID-specific study, Jinhua Qinggan granules were found to significantly alleviate fever, cough, fatigue, sputum, anxiety and need for hospitalization. Most recently, a Pakistani trial found the TCM remedy was 82.6% effective when used in COVID-positive patients treated at home for mild to moderate infection
      • In February 2022, Saudi Arabian researchers published a paper detailing how one of its main components, artemisinin, and its derivatives inhibit SARS-CoV-2 infection by binding to an enzyme the virus uses to multiply within the cell and disarm the host’s immune defenses
      • Artemisia annua is also bioactive against other viruses, including cytomegalovirus, hepatitis B and C, and members of the herpes family, including herpes virus type 1 and Epstein-Barr”

MATH+ for Treating Coronavirus Disease

From Mercola:

This highly effective treatment is mostly made of natural meds, and is largely ignored by conventional medicine:

  • Early in the pandemic, five critical care physicians formed the Front Line COVID-19 Critical Care Working Group (FLCCC), which developed the highly effective COVID-19 treatment protocol known as MATH+
  • MATH+ involves a combination of:
    • Prescribed medicines: ivermectin and methylprednisolone; and
    • OTC supplements: vitamin C, thiamine (a B-vitamin0, vitamin D and other readily available substances such as quercetin to treat COVID-19

Vitamins C and D for Treating Coronavirus Disease 

[Cat’s Note: adequate levels of vitamins C and D are also helpful in avoiding COVID.]

The following bullets are from Mercola (1i); see also my articles on Vitamin C and Vitamin D.

  • Vitamin C strengthens your immune system and kills pathogens, including viruses, when taken in high doses
  • Other important immune boosting nutrients are vitamin D, magnesium and zinc
  • If you own a sauna, now’s the time to put it to regular use. By increasing your core body temperature, which is what happens when you have a fever, your body becomes more efficient at killing pathogens

The following text is my own:

Vitamin C for the common cold:

You may remember Dr Linus Pauling declaring that vitamin C can be used to combat respiratory diseases like the common cold. Many people thought he was crazy, but the use of high doses of Vitamin C intravenously to treat COVID-19 is proving him right.

I met Dr. Pauling when he gave a talk at Reed College in Portland in the late 70s, that included his ongoing research about vitamin C (4) to effectively treat a cold and related viruses. At the time, I was in graduate school studying quantum chemistry. It is again making the headlines because of its use in the Wuhan China epidemic; it is believed to be why the rapid spread of the virus there was finally slowed. Now that the disease has spread to the USA, conventional medicine is finally beginning to accept the use of Vitamins C and D for treatment of the respiratory diseases caused by the coronavirus.

While vitamin C may not “cure” the disease, it can make it less serious/deadly, and may also minimize the spread of the disease, and may also prevent you from succumbing to it. Although high-dose IV treatment with vitamin C is the most effective, even taking it supplementally at doses higher than the RDA can help you avoid and even treat the disease. I’m currently taking: 

    • liposomal vitamin C: 1000 mg gel-cap twice daily (after lunch and dinner);
    • 300 mg liquid vitamin C supplement (plus fresh fruits: orange, berries, apple and avocado) in my daily smoothie,
    • 80 mg /day by adding acerola extract powder (from a fruit native to central America that is rich in vitamin C) to my daily smoothie, and
    • 500 mg 3-times daily as part of Alphasorb-C supplement (buffered vitamin C and alpha lipoic acid).

That totals to 3880 mg vitamin C daily. And if I do start to get sick, I’ll increase the liposomal-C to 3-times daily, increasing the total amount to 4800 mg/day.

While there are no clinical trials investigating vitamin D for coronavirus specifically, there are plenty of data showing it’s an important component in the prevention and treatment of influenza and upper respiratory tract infections.” See also Mercola’s article: Vitamins C and D Finally Adopted as Coronavirus Treatment (1a)”

Vitamin D: From the e-book, “Stealth Strategies to Stop COVID Cold (see,” of which Mercola is one of the authors:

“A recent study at the University of Chicago of over 4,000 patients8 found that untreated vitamin D deficiency was associated with an increased risk for COVID-19 infection. Another observational study involving 212 patients in Southeast Asia found that of those with a critical or severe case of COVID-19, only 4% had normal levels, while 96% of those with a mild case of COVID-19 had normal vitamin D levels.

Another retrospective study involving 780 cases in Indonesia found that vitamin D status was strongly associated with COVID-19 mortality.” [For a summary of their findings, see the impressive Figure 3 from that e-book (page 5], “which demonstrates a radical reduction in the death rate from COVID-19 as vitamin D levels increase to over 30 ng/ml.

Other nutrients that may increase effectiveness of Vitamin D, also from the e-book, “Stealth Strategies to Stop COVID Cold (see

  • Magnesium helps to activate vitamin D; take at least 500 mg magnesium/day;
  • Vitamin K2, 150-200 mcg/day, works synergistically with vitamin D. An excellent food source of this vitamin is brie cheese, which I eat daily with sliced apple.

Glycyrrhizin in Licorice; Can it Help Fight SARS Viruses?

From Mercola (1e)

Glycyrrhizin (1f) was valued in ancient Arabia and Greece for treating coughs and in China for relieving irritation of the mucous membranes. In modern times, glycyrrhizin has been shown to be a formidable antiviral, fighting herpes, HIV, hepatitis, influenza, encephalitis and pneumonia as well as less known viruses like respiratory syncytial virus, arboviruses, vaccinia virus and vesicular stomatitis virus.”

It works against SARS (virus SARS-CoV-1) that emerged in 2003; because SARS-CoV-2 is closely related, there is hope it may be useful in treating COVID-19. “According to the Journal of General Virology, glycyrrhizin’s method of stopping the replication of SARS viruses may differ from other treatments that have been tried. [Its] antiviral effects may be exerted, for example, during virus adsorption or release.” (8)


from Mercola article: “Ketones Combat Inflammation and Improve Metabolic Function” (1m)

Ketones are water-soluble fats that aid in tissue healing. They are also very helpful in cases of viral infections such as COVID-19, as they reestablish cellular homeostasis, provide rapid energy, recharge your antioxidants and control oxidation within the cell…

Ketones also suppress inflammatory pathways present as a result of an infection; they elevate NAD+, which in turn upregulates SIRT genes, SIRT3 in particular, that directly control inflammation…

Baking soda and Alka-Seltzer Gold help squelch excessive inflammation by immediately neutralizing peroxynitrites, which are among the most damaging free radicals there are, and work synergistically with ketones to preserve bone and prevent the loss of muscle.”

See his article (1m) for more detail.

Where do you get ketones? by eating good quality natural fats or fatty-foods, such as coconut oil, butter, and avocados. The body breaks down the fats, and one of the results of that break-down is ketones (hence the name for the “ketogenic diet”).

See also my article: Ketogenic Diet (Intro).

NAC (N-Acetyl Cysteine) Combats COVID

From Mercola; his article summary is listed below; see his article (1k) for more detail. Article also has educational 26 min video about oxidative stress, which is a factor in COVID-19.

  • “NAC [is a natural substance that] has a long history of use as a first-aid remedy for acetaminophen poisoning. Compelling research suggests it may also be useful against COVID-19.
  • By raising glutathione, NAC combats oxidative stress, which is a main cause of the cytokine storm associated with COVID-19. NAC also inhibits hypercoagulation and breaks up blood clots, which is another complication seen in some COVID-19 cases.
  • NAC helps loosen thick mucus in the lungs and improves a variety of lung-related problems, including pneumonia and acute respiratory distress syndrome (ARDS), both of which are common characteristics of COVID-19.
  • NAC has been shown to inhibit replication of influenza virus.
  • Aside from increasing glutathione, NAC may also prevent or improve COVID-19 infection by improving T cell response and modulating inflammation.”

Also the article discusses the FDA crackdown on NAC as a supplement, so that pharmaceutical companies can copyright it for big $$$.

Natural Cough and Lung Remedies: Top 10¾

Cough and trouble breathing are primary symptoms of COVID-19, as well as common cold, influenza and pneumonia. A Green Med Info article provides 10 natural remedies for these symptoms. See Notes on Natural Health and Healing Topics, A-C; scroll down to “Cough and Lung Remedies” for more detail (originally from a Green Med Info article (2b)

Nebulized Hydrogen Peroxide

Cat’s note: hydrogen peroxide should be diluted with saline, before using the nebulizer. Mercola’s article (1p) includes details on how to do the dilution.

“the peroxide needs to be diluted with saline. I recommend diluting it down to 0.1%. Brownstein recommends diluting it to 0.04”

See Mercola video included in his article: “How COVID-19 ‘Vaccines’ May Destroy the Lives of Millions” (1g). In his article, scroll down about 7/8 of the way to view the video, and learn how to do the nebulization and use the end product. He writes:

Nebulizing hydrogen peroxide into your sinuses, throat and lungs is a simple, straightforward way to augment your body’s natural expression of hydrogen peroxide to combat infections and can be used both prophylactically after known exposure to COVID-19 and as a treatment for mild, moderate and even severe illness.

Another Mercola article (1p) provides more detail about the success of using nebulized hydrogen peroxide (along with other nutrients such as iodine, Vitamins A, C, D3, and more).

About the nebulizer:

“to optimize your benefits, be sure to buy an electric tabletop jet nebulizer. The battery-driven handheld versions simply aren’t as effective. As Brownstein points out, in nearly all cases where patients were not getting better, they were using a handheld nebulizer. Once they got a more powerful version that can drive the peroxide deep into the lungs, the treatment started working as it should. “

[Cat’s note: hydrogen peroxide should be diluted with saline, before using the nebulizer. Mercola’s article (1p) includes details on how to do the dilution.]

About recommended vitamins and iodine:

    • Dr. David Brownstein has successfully treated more than 230 COVID-19 patients using immune boosting strategies such as intravenous or nebulized peroxide, iodine, oral vitamins A, C and D, and intramuscular ozone. None has died from the infection.
    • Beta carotene is a water-soluble form of vitamin A that does not provide immune boosting benefits. For that, you need the fat-soluble form, so make sure you’re taking emulsified vitamin A.
    • At the first signs of illness, Brownstein recommends taking 100,000 units of vitamin A and 50,000 units of vitamin D3 per day for four days, along with 1,000 milligrams of vitamin C per hour during waking hours as well as 25 mg of iodine until symptoms recede. Nebulizing peroxide with iodine is also recommended.
    • Hydrogen peroxide is a topical disinfectant that kills viruses on contact. It’s also an oxidative therapy that stimulates the redox pathway, thereby stimulating energy production and repair cells. It also improves oxygenation and may have a detoxifying effect on your lungs.

[Cat’s note: I take natural cod liver oil from fermented cod, which includes the proper forms of vitamins A and D. This is the form of cod liver oil taken by our ancestors (prior to the late 1800s). It has a very sharp taste, so I blend it with my smoothie.]

Regarding Iodine (quoting Dr. Brownstein (1p)):

    • “The average dose of iodine over the years that I’ve had my patients on is 25 milligrams a day. And it’s a combination of iodine and iodide, which is found in Lugol’s solution. That was quickly added into that four-part regimen, and that made a huge difference. People liked that. They felt better with it.”

[Cat’s note: I used to take Lugol’s to help my thyroid, but had to stop taking it because I was no longer deficient in iodine. It’s a good idea to have a blood test to determine your iodine level.]

About the nebulizer (bold text is added by Cat):

“to optimize your benefits, be sure to buy an electric tabletop jet nebulizer. The battery-driven handheld versions simply aren’t as effective. As Brownstein points out, in nearly all cases where patients were not getting better, they were using a handheld nebulizer. Once they got a more powerful version that can drive the peroxide deep into the lungs, the treatment started working as it should. “

Quercitin for Preventing/Treating Coronavirus (and other viruses)

from Mercola: Quercetin and Vitamin D – Allies Against Coronavirus (1c):

Quercetin is a powerful immune booster and broad-spectrum antiviral. It also inhibits the release of pro-inflammatory cytokines, which may be beneficial since serious COVID-19 infection and subsequent death appears to be due to cytokine storm activity.

Other nutraceuticals thought to be useful in the prevention of coronavirus infection include NAC, spirulina, beta-glucan, glucosamine, selenium, zinc, lipoic acid and sulforaphane. … Coconut oil may also be useful.

Seaweed for Treating Coronavirus

from Mercola: Seaweed for SARS CoV-2 (1j):

  • “A dose response study was performed with five seaweed extracts, revealing the effective concentration that inhibits 50% of viral activity — known as EC50; a lower EC50 is indicative of a more effective extract.
  • The results revealed that the seaweed extract RPI-27 had an EC50 of about 83 nanomolar, compared to remdesivir’s 770 nanomolar.
  • Remdesivir is an antiviral drug that has shown some promise in treating COVID-19; however, serious side effects have been reported, including kidney failure.
  • With the seaweed extracts, no cellular toxicity was found, even at the highest concentrations, and in some cases they outperformed Remdesivir in fighting SARS-CoV-2.”

Thiamine (Vitamin B1) forTreating Coronavirus

from Mercola (1d) 

Taking thiamine daily, along with vitamins C and D, zinc and quercetin can help protect against infectious respiratory illness such as influenza and the coronavirus. Another important nutrient is magnesium, which “is required for the activation of both thiamine and vitamin D.”

While the minimum daily intake for thiamine is about 1 mg, taking 200 mg thiamine every 12 hours, along with high-dose vitamin C (IV), has been shown to be effective against sepsis, a primary cause of COVID-19 mortality. “Thiamine deficiency syndrome (beriberi) has many similarities to sepsis.” There is also a “link between thiamine deficiency and fever.”

For those with thyroid/adrenal problems, Isabella Wentz (Hashimoto’s Protocol) recommends taking a daily dose of 600 mg thiamine (B1) for 3 – 6 months. See my article on Vitamin B-Complex for more.
