Wow. That is exactly my go-to-list. I've got some other things on hand like hydrogen peroxide (3%, which can be nebulized against "the virus"), Listerine (original), anise extract plus star anise, Ricola drops (have menthol), and some Ivermectin. I use some colloidal silver, too.
I've begun to feel a bit better overall since I started taking all these things. I try to add onions and garlic now and again, too.
For some specific issues I have I've added occasional L-carnitine as well as phosphatidyl serine.
Anons can probably become like old fashioned "chemists" who used to give people their medicines back in the day. Reminds me of how among "anti-vaxxers" it used to be said that if you wanted to know all about vaccines just ask the mother of an autistic child.
