He should definitely have a supply of collodial silver on hand as well. Of is known to kill viruses as well as bacteria.
I heard that Snake Oil was the best remedy.
I first learned of colloidal silver when I heard a doctor discussing it on his weekly radio program. He believed in natural remedies first, but traditional medicine when needed. He pointed out that in the days before refrigeration, people put a silver dollar in their milk because it made it keep longer, though they didn’t know why. Silver kills bacteria. This same doctor claimed it will also kill a virus, which isn’t a living organism on it’s own; it must have a host to live and replicate.
I have actually used it to stop colds, sore throats and even a bladder infections, so we always keep some on hand and take it when we go on vacations, as well.
My veterinarian husband (who also takes colloidal silver) backs up the claim that silver is medically beneficial. It is used in devices and bandages in the medical field.
