Lemon balm a member of the mint family, is considered a calming herb. It was used as far back as the Middle Ages to reduce stress and anxiety, promote sleep, improve appetite, and ease pain and discomfort from indigestion.
Lemon Balm was dedicated to the goddess Diana, and used medicinally by the Greeks some 2,000 years ago. In the Middles Ages lemon balm was used to soothe tension, to dress wounds, and as a cure for toothache, skin eruptions, mad dog bites, crooked necks, and sickness during pregnancy. It was even said to prevent baldness. As a medicinal plant, lemon balm has traditionally been employed against bronchial inflammation, earache, fever, flatulence, headaches, high blood pressure, influenza, mood disorders, palpitations, toothache and vomiting. A tea made from Lemon balm leaves is said to soothe menstrual cramps and helps relieve PMS.
The herb is used for nervous agitation, sleeping problems, functional gastrointestinal complaints, menstrual cramps and urinary spasms. It is thought that the volatile oils in lemon balm contain chemicals that relax muscles, particularly in the bladder, stomach, and uterus, thereby relieving cramps, gas, and nausea.
