Question

why keeping onion in your armpit rises your body temperatue

Answer 1

hello user,

when we put the slices of onion under the armpits the bacteria or viruses enter in our skin and kill those bacteria which is necessary for our body,in other words you could encourage lymph node drainage from the area, by keeping onions under your armpit your fever will increase, beacause onions attracts viruses and other microorganisms towards itself which will finally increase the number of microorganisms near your body and the body will trigger a defence mechanism to fight them as they can be potential threat and we know that virus Cannot withstand high tempratures therefore your body temperature will increase to kill all the virus near it  i.e you'll get fever.

hope it helps u dear
