We grow our own peppermint and then soak the herb in olive oil for 4-6 months before draining and using in our peppermint soap. We then add premium Willamette Valley Peppermint essential oil known for its high menthol component. This combination gives our soap an edge over other peppermint soaps. It will definitely give you a wake up call in your morning shower. Clean, crisp scent that will leave your whole body feeling refreshed!
