Pennyroyal Supplement: What It Is and How It Works

Pennyroyal is a tiny, aromatic plant that’s been used for centuries in folk medicine. Today you’ll mostly find it as dried leaves, a tincture, or a concentrated oil that people call a pennyroyal supplement. The active compounds, especially pulegone, give it a strong scent and the ability to affect the body’s muscle tone and digestion.

Common Uses and What to Expect

People turn to pennyroyal for a few specific reasons. It’s popular for easing occasional digestive upset, like bloating or mild cramping. Some users say it helps with short‑term respiratory congestion when inhaled as steam. A few also try it to calm menstrual cramps, although the evidence is mostly anecdotal.

Because the smell is strong, pennyroyal oil is also used as a natural insect repellent. A few drops on a cloth or in a diffuser can keep moths and flies at bay without chemicals. Just remember that a little goes a long way—over‑using the oil can cause strong irritation.

How to Take It Safely

If you decide to try a pennyroyal supplement, start with the lowest dose possible. For dried herb tea, steep ½ teaspoon in hot water for 5‑10 minutes and drink no more than one cup a day. For oil, a single drop diluted in a carrier oil (like coconut oil) is enough for external use.

Never ingest pure pennyroyal oil. The concentrated form contains high levels of pulegone, which can be toxic to the liver and kidneys if swallowed. Pregnant or nursing women should avoid pennyroyal altogether because it can stimulate uterine contractions.

Watch for side effects. A mild headache, nausea, or tongue tingling can signal you’ve taken too much. If any of these symptoms appear, stop using the supplement and drink plenty of water. If they persist, talk to a healthcare professional.

When buying, choose reputable brands that test for purity and label the exact amount of pulegone. Look for third‑party lab results on the product page. Cheap, unlabeled bulk powders often skip safety checks, increasing the risk of contamination.

Mixing pennyroyal with other herbal sedatives, like valerian or kava, can amplify calming effects and lead to drowsiness. If you’re on prescription medication, especially for liver conditions, check with a doctor before adding pennyroyal to your routine.

Bottom line: pennyroyal can be a handy, natural option for mild digestive or respiratory complaints and as an insect repellent, but it demands respect. Stick to low doses, avoid internal use of the pure oil, and keep it away from pregnant folks. With those precautions, you can enjoy the herb’s benefits without the nasty side effects.
