Favorite weed: Mullein

Mullein is used for cough, whooping cough, tuberculosis, bronchitis, hoarseness, pneumonia, earaches, colds, chills, flu, swine flu, fever, allergies, tonsillitis, and sore throat. Other uses include asthma, diarrhea, colic, gastrointestinal bleeding, migraines, joint pain, and gout.

I've never used it for any of these ailments.  I just adore the fuzzy leaves and the way it blooms.  Now I'm wondering if it could cure covid!?!  Is this the miracle drug we all need?
