To recover from Covid--if Biff and Carolyn have only had Covid-19 for 1-3 days Take quercetin 500mg three to four times daily Take zinc 25mg twice daily. Do not take the zinc with grains, nuts, beans, or seeds. If they have had Covid longer than three days, this will not work. You have to be within a three day window. Quercetin and zinc are natural supplements that would not interact with any other drugs. You could also try to find some ivermectin. You could also try to find an IV clinic in your area that knows how to nebulize hydrogen peroxide, or give it to them IV. An IV clinic might also be able to tell you about ozone therapy to help them recover from exhaustion. I am not saying that any of these things are substitutes for drugs. They should still keep taking any drugs that their doctor has prescribed. They were having success using the antibody treatment of Regeneron to help people with Covid, though there is some controversy about using it now, because some people think it might not be effective with the omicron variant, and it may not be possible to get it anymore anyway. That is something else they can talk about with their doctor. To prevent Covid from occurring again in the future Take quercetin 500mg three to four times daily. Take zinc 25mg twice daily. Do not take the zinc with grains, nuts, beans, or seeds. It would also be good if they could try to get set up with a doctor who is willing to prescribe hydroxychloroquine, ivermectin, or a steroid for the lungs if they do come down with Covid. Hydroxychloroquine does the same thing that quercetin does. Also try to do some general things that build up the immune system, like taking vitamin D, vitamin A, or Vitamin C, or taking other herbal supplements that naturally strengthen the immune system, like elderberry. Also, I don't know about Alzheimers, but I do have some information about dementia. There might be some cross relevance. Search for this video on YouTube "Glutathione, Oxidative Stress and N-Acetylcysteine (NAC) in Psychiatric Disorders." It was made by a psychiatrist. He is talking about a natural treatment for dementia that might help. I don’t know for sure if it would work, but he is a doctor and he seems to believe in it. If it works for dementia, then it might work for Alzheimers.
