After long research I found out that fever is actually a normal function of the body.
This is true, but as with diarrhea, fevers should stop once they have completed a useful purpose such as burning toxins. Before discovering Hippocratic medicine, I was wrongly persuaded to always view diarrhea and fever as intrinsically bad rather than as mechanisms of healing a sick body.
A fever can be a most feared thing. Fever ranks as one of the major symptoms, or complaints, that lead people to consult their doctor, or seek medical help.
In Greek Medicine, fever, or pyrexia, is seen as a manifestation of the Fire element in the human body. A localized manifestation of heat, or Fire, is inflammation; fever is basically inflammation that has spread through the lymphatic or circulatory systems and gone systemic to affect the whole organism.
Many fevers can be broken through sweating. Sweat is the waste product of the Fire element, which drains excess heat and fever from the body. Although Western medicine tends to look upon fever as something that should always be brought down or suppressed, in Greek Medicine, fever isn't always a bad thing. Fever is seen as a protective cleansing response, or catharsis, of the organism; by manifesting a fever, the elevated metabolic heat can burn off toxins, pathogens and superfluous morbid humors at a faster rate once they have accumulated to critical levels.
And so, as a natural protective cleansing response of the organism, many fevers tend to be self-limiting, and of limited duration. After the offending toxins and superfluous morbid humors have been consumed, the fever has served its purpose and run its course, homeostasis is reestablished, and the body returns to normal.http://www.greekmedicine.net/pathology/Differentiation_of_Fever.html
