Herbs/Pennyroyal or mint?

I volunteer at a community garden, and for years we've been growing and selling a plant as 'round leaved mint'. Today, someone said it might be pennyroyal! Obviously, if this is the case then we need to stop selling it as a cullinary herb immediately, as it is poisonous and can cause miscarriage.

However, I have been searching Google for hours and have failed to make a positive ID on this thing one way or another, because there are just so many varieties of mint and pennyroyal, and they can hybridise too.

It smells just like Trebor mints or toothpaste, has very round (definitely not oval) leaves with a very thin edge of purple, and square purple upright stems, and it's very invasive. Can you help?

I believe that this sounds like pennyroyal.The mint does not sound like peppermint or spearmint from seed. The kentucky colonel spearmint is stronger.It is true about pennyroyal being unsafe to ingest. Good as insect protection on your pets.

Hope this helps.

I have been growing herbs organically for 27 years. I have also written and self-published, loose leaf binder, "Herbmans Journal". 2008 is my last year at Smile Herb Shop. I plan to grow herbs in my small back yard and sell at David's Natural Store in Columbia, Md. on saturdays. I also will return to the Baltimore Herb Festival in May 2009(memorial day weekend).I used the word organically grown, but the state came into the picture and stated that I could not use the word unless I become certified & paid a $300.00 fee. I decided to add to my name (99% chemical-free) since nothing on this planet is 100%, except Jesus Christ, taxes & death. My customers were satisfied with this instead of paying a large fee and raising my prices,with no guarantee that it is organic except for a label.Their belief was in my word.
