Pennyroyal Oil is steam-distilled from the Mentha pulegium herb, which is wild grown throughout much of Morocco. The oil’s aroma is green and minty, similar to peppermint and catnip, though with a strong herbal undertone. As a member of the mint family, pennyroyal oil has an immediate cooling and mentholic top note, making it a common inclusion alongside other herbal ingredients within herbaceous fragrance accords. Pennyroyal is also a small component of blackcurrant flavorings.
