If you have the proper organs to filter alcohol. Missing some parts guys.
Get some fresh ginger root. Grate 4-6 tablespoons into a medium sized pot filled 3/4 way with water. Bring that to a boil, then simmer for 20 mins. Strain it (if you want) and drink as much as you can. You can sweeten it, too, if you prefer. A natural sweetener like raw sugar or honey is best.
If your remaining organs can handle spice, go heavy on the ginger. And add 1 or 2 whole cayenne peppers (dried) along with the ginger.
Ginger is a thermogenic herb. Which means it cranks up the internal furnace of the body. It will help break a fever, safely and naturally. Ginger has antibacterial/antimicrobial properties. Google it if you want more info on all of its benefits.
