Pau d'arco standardized extract capsules combined with olive leaf extract, standardized capsules, work wonders to combat virus like the flu. Antibiotics are incapable of addressing a virus, but those herbal extracts combined helped my husband recover from the flu days before his friends, who also suffered.
Add Zinc as an extra tissue cleanser, but take it with food and don't take too much or you'll feel sick to your stomach.
Drink lots of water, avoid white flour products and dairy because those cause mucous and that just compounds feeling sick.
(Hug) God bring you healing and peace.
Holding you in my prayers.
