Peppermint has a hint of purple in its stem, and shorter, darker leaves than the garden mint variety most people Ive met know of.
Peppermint is actually a natural hybrid cross between water mint and spearmint. Mint leaves were rubbed on tables to welcome guests in Greece, and mint tea is still customarily offered to arriving guests in the Middle East.
When picking peppermint for your own use, the fresh leaves will impart a superior flavor to dried leaves (such as for use in the tisanes I sell). Look for fresh leaves that are green in color without any dark spots or yellowing. In addition to using fresh mint leaves in tea, you can add them to soups, fruit salad or gazpacho.
I recommend you to use mint in most of my flu remedies 
and even coffee at times.
