Black Pepper Diffuser OilThe Scent: Luxurious, subtle, and mysterious, like the peppercorns themselves. Black pepper's pungent bite comes from the alkaloid piperine and piperidine, combined with resins found mostly in the seeds. Its aromatic, slightly musty odor comes from the volatile oils found largely in the flesh and skin. These are the oils that go into creating this elegant Black Pepper scent.
