Medicinal Uses of Mint (not horse mint, or bee balm, but family Mentha)
As for the garden of mint, the very smell of it alone recovers and refreshes our spirits, as the taste stirs up our appetite for meat.
–Pliny the Elder
Mint has properties related to soothing toothaches, indigestion, stomach cramps, menstrual cramps, flatulence, upset stomach, nausea, vomiting, and colic in children.
Make a tea out of fresh or dried leaves for a tasty and refreshing after-dinner stomach soother. For the younger crowd, it can also be heated with milk for the same effect (and they will like it).
Mint also can be used as an appetite stimulant. It reduces hunger for a short time, but when the effects wear off the hunger returns stronger than before. For those lucky enough to need to gain a few pounds, a tea might be tried 30 minutes before a meal for appetite stimulation.
Peppermint is much more effective as a medicinal herb than Spearmint, which is mostly a culinary herb. However, use spearmint in place of peppermint in cases of digestive problems or colic in very small children, as peppermint may be a bit too strong.
For a refreshing and cleansing facial wash, place a handful of bruised mint leaves (any kind) in a quart-sized pan of cool water. Let sit for an hour or so, then chill in the refrigerator and use as desired. Lastly, mint combined with rosemary in a vinegar is reported to help control dandruff (place the sprigs in a bottle that can be tightly sealed, and let sit for at least a week out of direct sunlight).
Use mint to cover the taste of other medicinal herbs.
