Is there a therapy for Covid?

Thus far, we have seen numerous therapies appear in the news and then quickly disappear. What ever happened to plasma therapy, HCR, monoclonals, etc.? According to some doctors, these therapies are still out there and do work, but all practicioners have somehow been silenced. Were they silenced because these cures don't work and therefore they were considered inattenible or were they silenced because someone out there doesn't want these therapies to be known?

Mainstream media has given word to numerous doctors who more or less promote the same thing. We sincerely hope that all other doctors will take the time to illustrate these therapies and show their laboratory and hospital results.
