I used those articles during COVID-19 to get me through COVID-19 Delta strain, the worst COVID-19 strain in June 2020 which my postman delivered. So much for keeping a distance, a young man in his very early 20's I would imagine.
I use Cordyceps Sinensis after first starting with Cordyceps Militaris but I avoid that now because of one of it's constituents which is significantly higher than C. Sinensis which is strongly COX-2 inhibiting which can be damaging to the kidneys if used in excess. There are stories in Thailand where people experienced kidney failure using Cordyceps Militaris extracts. BTW Cordyceps has been shown to raise male sex hormones which tend to be low in ME because of the pituitary dysfunction. It's also fairly anti-inflammatory which is helpful.
There are a quite a few other herbs that he recommends to counter the inflammatory processes created by COVID-19. Some of them might also be helpful for Long COVID. There is a pdf which gives recommendations for recovering taste and smell which can be disrupted by COVID-19.
I don't like Red Ginseng, I use Siberian Ginseng which is milder and less stimulating and cheaper. It does seem to sensitize the body to cortisol which lowers the adrenal cortisol production where less does more. It does also positively affect the natural killer cell function which is important with Lyme disease.
Take a look at the free pdf's to see if anything is useful to you.
