Although the genus Carum counts 25 species, through the Northern hemisphere (Danert et al. 1975), only Carum carvi L. has an economical importance, being used and cultivated in several regions (Figure 1). This species has been the topic of a wide row of investigations, and-in the course of production-of accumulated practical knowledge. The majority of these valuable data is collected in this book, part of them published elsewhere, part of them nowhere.
