The deep green leaves of this fresh-tasting herb grow in pointy spearhead formations. Perhaps this is what makes spearmint such a tried-and-true weapon against adversaries like headaches, tension, nausea and stomach aches. It might also explain why it’s such a sharp base for tea mojitos. Just add a tablespoon of lime, a shot of rum and a little sugar or agave to your cup. Serve hot or chilled.
