Hi,

Oleum jecoris aselli. Most probably it may restore the fever and if you
don't
suppress it again, the cough will slowly disappear. You may even use it in
crude form,
nightly rubbing it on her skin.

The next best is sang which covers the following symptoms.
COUGH - DRY - lying, while
COUGH - DRY - sitting, while - amel.
COUGH - DRY - sleep - disturbing
COUGH - DRY - spasmodic, exhausting cough especially in children - night
lying down and going to cold room to sleep

with best wishes,
V.T.Yekkirala
