 viable and economical treatments banned

As someone who tries to keep up with the evolving medical literature on treatment of Covid-19, I'd greatly appreciate some clarification and evidence regarding this statement. Does "viable" mean "proven effective," "possibly effective," or if something else, what? I'd also appreciate evidence about which specific treatments you are referring to, who has banned them and how, and why? Thanks in advance.
