I was part of an earlier discussion of suramin here. It seems that for treatment of African sleeping sickness and River blindness the drug is injected.

The drug has been trialed in autism, but I wonder if it is useful if taken orally?

I have found discussion of something called shikimic acid, with beneficial health effects but do not know if a source of shikimic acid is beneficial against "spike protein disease" in the absence of suramin.

Star anise would be a good source of shikimic acid (if my understanding is correct) but not, I don't believe a source of suramin.

Some species of pine needles apparently would have both, but what is the effect if taken orally? Found anon post some time ago, that if memory serves mentioned pine sap or some such as a cure for worms.

Caution with all these ideas! However, I think we may be onto some things with this line of exploration.
