Also I make seasonally honey, onion, and garlic in a mason jar (small one) so it’s a home made caugh and cold syrup.
It needs to sit a few weeks so it might not help you now but you can make a small batch for the next time.
Right now you can put a thick onion slice on bottom of your feet with a sock over them and sleep that way tonight.
Do you have essential oils or know anyone that sells them?
Make a flu bomb in a roller ball or take internally in a veggie cap.
Oregano
Lemon
Melaleuca
On Guard (Dotera) / Thieves (Young Living) (these are a blend of other oils Wild Orange, Clove, Cinnamon Bark, Eucalyptus, Rosemary)
