Always Read the Label Before Applying: Laughing Along With a Limerick

Having used a new soothing balm.

But when she started to burn,

She ran to the bathroom as she squirmed,

Trying to get that stuff off of her palm.

Written for Laughing Along with a Limerick #269 from Esther Chilton. The prompt is Calm.
