Pennyroyal

Latin Name
Mentha pulegium

General Description
Pennyroyal, a plant with smooth oval leaves, has been used since ancient times as a cough remedy and digestive aid, as well as a flea repellent. The strong aroma of its infusion acts as a decongestant and possibly as an expectorant, helping to remove excess mucus from the lungs; it is therefore useful for coughs. While the dried herb is safe in recommended doses, the oil of the pennyroyal plant should not be ingested, since even small amounts of it are toxic.

Target Ailments

• Colds, coughs, premenstrual syndrome, menstrual cramps, gas, indigestion and anxiety. (Used internally.)
  
• Fleas on pets. (Used as you would commercial flea powder.)

Preparations
Over the counter:
Pennyroyal is available as tinctures and as dried leaves and flowers.

At home:
Tea: 1 to 2 tsp. dried leaves steeped in 1 cup boiling water for 10 to 15 minutes, or 1 tbsp. dried herb mixed with 1 cup warm water.

Special Information

• WARNING: Present-day practitioners advise against taking pennyroyal oil in any amount, because of its toxicity.
  
• Do not exceed the recommended dose of the herb and do not take for longer than a week at a time.
  
• Pennyroyal stimulates uterine contractions and should not be used during pregnancy.
  
• In the past pennyroyal has been used to induce abortion because of its ability to stimulate menstruation and strengthen uterine contractions; but it should never be used for that purpose because it may cause serious complications, such as hemorrhage or convulsions. The amount needed to abort a fetus is close to a lethal dose.
  
• Do not give to children younger than 2 years of age.
