Mentha piperita
Peppermint is used primarily for its stimulating, stomachic, and carminative properties in treating indigestion, flatulence (gas), and colic. Peppermint is usually taken in a moderately warm tea prepared from the leaves, several cups being slowly sipped to bring fairly prompt relief.

As an aid to digestion, its activity is due primarily to its contained volatile oil, which exists in the herb (leaves and flowering tops) in concentrations ranging from 1 to 3 percent.

In addition, the volatile oil acts as a spasmolytic, reducing the tonus of the lower esophageal (cardial) sphincter and facilitating eructation (belching). This antispasmodic property may also account for the popularity of peppermint tea as a household remedy for menstrual cramps. Peppermint oil temporarily inhibits hunger pangs in the stomach, but soon the stomach resumes its peristaltic movements, which then become stronger than before. In this way it works to stimulate the appetite.
