I too have pneumonia ..
Known as a wind/ heat condition in Chinese medicine .
A cold is completely different treatment
Considered wind/cold that enters through the back of the neck .
Both are benefited by a diaphoretic . Which helps facilitate breaking a fever for flu. And getting rid of excess cold in the body from the common cold.
Go get peppermint tea.. make 3 or 4 hot cups of it ... chug them down as fast as you can without Burning yourself.. bundle up and hop under a sleeping bag. And sweat it out. Then shower and wash everything and get fresh air .
The fever is your body's response to pathogens. You want to facilitate it not stop it .
On a side note I've had to cut down my kava usage because of losing so many fluids from the flu and pneumonia ! So be careful of that aspect and extra water !
