Ice cream for tonsillitis

My neighbor's child was sick with tonsillitis. From ice cream. What drugs to give her? How to make it healthier faster?
Something that no one would dare to do. She gave to child  another ice cream. Likelihood that the disease disappear after this is a small one, but in this case it worked.

Tonsillitis is an infection or inflammation of the tonsils. Tonsils are masses of lymphoid tissue situated on either side of the throat, above and behind the tongue part of the body's immune system.

How then worked ice cream  as a drugs? Simple: infection is the result of bacteria, microbes. Ice cream is cold and kills most of those bacteria allowing  to immune system to do its job.
Unfortunately this "treatment" does not always work.
