Pennyroyal Peppermint Petasites Poisoning
Mentha pulegium or Pennyroyal is a much debated mint species, which is said to be safe in limited amounts.
The tea can be used for ingestion (though there are much safer alternatives!), or to stimulate menstrual flow, but it is best known for its ability to induce abortion, however there is a case in which prolonged usage led to death.
Mints are generally good insect repellents and insecticides, but due to the additional toxicity of pennyroyal, it is even more suited as an insect repellent.
But, do not use pennyroyal as a flea repellent, because it is toxic to pets, even in small amounts.
Pennyroyal essential oil is highly toxic. Even small doses can be deadly.
Mentha x piperita or Peppermint is a hybrid mint, or more specifically, a cross of watermint and spearmint.
Peppermint contains B vitamins, calcium and potassium. It is rich in menthol, which acts as a local anesthetic and also has analgesic properties, so it acts as a painkiller. Like most mints, peppermint is a very good antipruritic and a natural insecticide.
Peppermint tea is traditionally used to treat diarrhea, vomiting, flatulence and Irritable Bowel Syndrome (IBS).
Peppermint, administered topically, is used for tension headaches, applied to the forehead and temples.
Peppermint tea is safe to drink. Peppermint contains pulegone, a toxic organic compound, which is neutralized when cooked.
The toxicity of peppermint is still being researched.
