As someone with CKD I want to know more about this...
Anything that ends with “ricin” as a suffix deserves to be treated carefully.
By the way, I have wondered about possibly getting a source lined up for a prophylactic supply of Ivermectin, just in case. Not that I have any maladies that I would take it for now, but just as an “in case of need” type thing- any opinions on that?
