In the pennyroyal the stamens protrude beyond the flower, while they are the same length in the peppermint.
The pennyroyal's throat has a slight hairiness that does not occur in the peppermint.

It is not easy to recognize clearly
The distinction between peppermint and pennyroyal is not easy. Crossing it with other types of mint also changes the flowers and leaves of peppermint. Sometimes it is no longer possible to determine which species it is, even with a closer examination.
If you are not entirely sure, you should leave such plants alone. Pennyroyal poisoning can cause serious discomfort.
Pennyroyal is no longer used as a medicinal plant
Because of its toxicity in all parts of the plant, pennyroyal no longer plays a role in today's natural medicine. In addition, recent research has shown that pennyroyal poison can damage the liver.
In the past, the herb was used to make tea, which was used for contraception and abortions. The deaths caused by ingestion helped identify the toxicity of the plant.
In small doses, pennyroyal may only be used as a spice.
Tips
Pennyroyal is an endangered species and is a protected species. It is therefore hardly to be feared that it will be confused with the frequently occurring peppermint.
