There are about 25 species of the mint plant and different ones have similar but different uses. The peppermint, which has small pink flowers, has leaves that produce an oil used in making jellies and sweets. The lemon bergamot mint plant makes an oil used in drinks and marinades. The Japanese mint produces menthol. And I have no idea where mine comes from. I really don't care either. Just so long as it does the trick!
