i thought i'd share a little knowledge about it:
from the point of a nurses son and E-Course Biology Pupil with a+ grades that chart is almost absolute nonsense. i wanna see you giving your kid water to drink and light food while it's fighting with 41°C body temperatures.
it's true, fever is a response to infections. but usually its not nearly as adequate or "perfect" as you may think. and of course you have to fight the infection along with the fever.
Basically an infection is nothing more than a poisoning - on bacteria level.
bacteria are processing nutrients from your body and are basically "peeing and pooping" into your blood. those excrements are usually non-toxic for most of bacteria.
some although are exerting toxic excrements. that's when we're talking about infection.
so there are two ways to deal with those infecting bacteria:
a) kill them
b) neutralise their poisonous exertions
a) the body's own instrument to kill them is to have them eaten by anti-cells and by raising your temperature.
just that some of those bacteria are happy with higher temperatures, else evolution would have made them extinct long ago.
as a non-natural measure you usually use disinfectant on 'dead' materials as well as externally on living beings and antibiotics on the inside. as with everything you eat or drink, too much of those is poisonous as well.
b) thats what you can do with herbs, which are basically natural drugs, and chemical drugs. e.g. ibuprofene isnt just a feverkiller. it is anti-inflammatory and pain reducing as well. without the stress of pain and fever mammals are usually better able to fight infections.
ever heard of the proverbe 'a good night's rest is the best medicine' ?
it isnt coming out of nowhere.
or aspirine: actually the receipt was gotten from indians who used to chew willow leaves when in pain or use them on their sick. acetyliy salicylic acid is naturally coming from the leaves and the barks of willowtrees (salix = willowtree, salix alba salicaceae = white or silverwillow).

but enough of that. i guess you got my point.
