I'd personally be very wary about ingesting Peppermint Essential Oil without talking to someone qualified first. I have read warnings about dangers of ingesting peppermint oil in certain instances.

NOTE: I'm going to have to sent my site with that information on it to a Mod. to make sure that I can post it. It is a commercial site so I'm not sure yet. I'll come back with the info. if I can.

The tea is beautiful. I'd stick with the tea or better still grow some and make tea with it that way.
