Try this other one: an infusion of thyme with honey. That's working with me. It helps to disinfection of broncheus, and honey is a natural antibiotic.

My fever has reduced substantially during the past two days (of course, not only for these brews, but they help). Right now I have 37.2ºC (normal body temperature is between 36.5 and 37ºC) at 2 am. I think I'm seeing the end of the road.

Hope you feel better after your feverish day.
