Pennyroyal has been used for centuries to treat feverish conditions. It promotes sweat, which helps to reduce fevers and cleanse toxins from the body through the skin. The herb is also a digestive that helps to relieve indigestion, flatulence and grumbling in the intestines (griping). It has been used to relieve cough, cold and flu symptoms, and its expectorant qualities help to expel phlegm and chest congestion, and alleviate dry hacking coughs. Pennyroyal helps to promote and regulate menstrual flow and may thus allay painful menstruation. It stimulates uterine contractions and was sometimes used to ease childbirth.
