I think pleurisy root from milkweed, is another one, good for severe pneumonia. European pioneers took it for breathing illnesses.

Noted as unsafe for heart, but heck if your dying coz of virus doesnt really matter eh?

Despite serious safety concerns, pleurisy root is used for coughs, swelling of the lining of the lungs (pleurisy), swelling of the air sacs in the lungs (pneumonitis), swelling of the airways (bronchitis), influenza, and swine flu. It is also used to treat disorders of the uterus, muscle spasms, and pain; to loosen mucus so it can be coughed up; and to promote sweating.
