We always referred to it as Cuban oregano.The oregano flavour comes from the essential oil, carvacrol, in the leaves. The Plectranthus amboinicus makes a great houseplant when kept pinched, but I find the scent a little overwhelming. It is sometimes used in East Indian, Indonesian , Korean and Malay cooking and for flavouring medicines
