Spearmint is one of the best known members of the mint family.  It is well known as a flavoring for gum and candy, but it also has healing properties.  Spearmint has much the same uses and properties as peppermint but is milder and therefore safer to use for children.  Tea made from spearmint is calming, soothing for upset stomachs, and helps with fevers, chills, cramps, colds and flu.  It is also used for motion sickness and morning sickness.  It freshens the breath and fights nasal congestion.  Externally, it is used on bruises and sore muscles, stings and insect bites.  It is antifungal, although not as good as oregano for that purpose.  It is also a repellent for insects, mice and rats.
