Quercetin-rich foods such as asparagus, elderberries, blueberries, cranberry juice, okra, water cress, onions, etc.
I also take Vitamin C, and elderberry gummies. I will discontinue use of elderberry if I get a fever. They do contain high amounts of quercetin. I also have zinc lozenges and quercetin to use in case of exposure or fever (I will plan on using an N95 mask as soon as my local community has more than two cases).
FYI on elderberry:

Quote:
Sambucus nigra (Elderberry): There is preclinical evidence that elderberry inhibits 22
replication and viral attachment of Human coronavirus NL63 (HCoV-NL63) , different than COVID-19, but a member of the coronavirus family. Sambucus appears most
effective in the prevention or early stage of corona virus infections. Sambucus
significantly increases inflammatory cytokines, including IL-B124 so should be discontinued with symptoms of infection (or positive test). An evidence-based systematic review of elderberry conducted by the Natural Standard Research Collaboration concluded that there is level B evidence to support the use of elderberry for influenza25 which may or may not be applicable to COVID-19 prevention. Typical dosing of 2:1 elderberry extract is 10mL -60mL daily for adults and 5mL-30mL daily for children.
