A newbie question on flowers and pruning

A newbie question on flowers and pruning

Sometime last week, my mom commented that she'd heard basil grows much stronger if the flowers are pruned. While I believe her because she's really good at caring for her plants, I wanted to know if this is true and if pruning the flowers will benefit the plant or hurt it (mainly because I've yet to get the hang of pruning ANYTHING and I'd hate to damage the basil plant).
