Change CSS to increase font-size inside li

I can’t work out how to increase my font-size in the ‘teaching points’ section of this WP post http://www.test.foamped.com/2013/07/abdo-pain/

I’d like it to be 15px like the rest yet it’s only 12px.

I can’t work out how to reference that section. Help!

Try

ul, ol {  padding-left: 19px;  font-size: 15px;}

Thanks
Ab
