Oregano is an upright perennial herb, growing to about thirty-two inches with a straight stem covered in hair. The leaves are dark green and oval in shape, and it has a profusion of pink flowers clustered at the top of the branches. Its name is actually derived from the Greek phrase, 'joy of the mountains'. Just married couples were crowned with wreaths of Oregano, and it was placed on graves to give peace to departed spirits. Oregano Essential Oil has a powerful, spicy, camphorous scent.
