CS>Re:CS>Shingles

[margaret B]

Hi everyone,
My friends granddaughter has just been diagnosed with shingles. She is only 2 
years old, so the doctor said that he can't treat it, that she should coat the 
rash in calamine lotion.
My question is, would she be too young to take CS internally? I have suggested 
that it would help externally.
Thank you for any input.
Best wishes,
Margaret.
