Boil a large onion, a few pegs of garlic and a large lemon sliced in two cups of water. Boil for a few minutes, then let simmer. Drink half cup twice per day. Boil enough if you want to go three days. Add more ingredients. That flu remedy got COVID from my body in twelve days. Google the benefits of the ingredients. It smells horrible. But worked for me. Hope you feel better. I drink eucalyptus tea with honey for sinus issues.
