FAV: Please Recap Natural Cures for Covid, I have a few co-workers with Symptoms lingering...

I have a few co-workers begging for any kind of cure that have lingering Covid symptoms. One of my co-workers has hair loss (tho she looks great?) but her finger nails are cracked and split / lifted up like a 90 year old. Her 17 year old son has a heart issue now and can't play football anymore. I have read great things on this site but can't track them all

Any helpful hints getting Covid out of the human body is greatly appreciated!!!
Love you guys!
