A Review of the Botany, Volatile Composition, Biochemical and Molecular Aspects, and Traditional Uses of .

L. is an aromatic medicinal plant widely cultivated in many world regions. has been increasingly acknowledged over the years as it provides an essential contribution to the food and pharmaceutical industries and cultural integrity. The commercial value of this species derives from its essential oil, whose application might be extended to various industries. The chemical composition of the essential oil depends on environmental conditions, location, and season during which the plants are collected, drying methods, extraction, and analytical conditions. The characterization and chemotyping of essential oil are extremely important because the changes in composition can affect biological activities. Several aspects of the plant's secondary metabolism, particularly volatile production in , are still unknown. However, understanding the molecular basis of flavor and aroma production is not an easy task to accomplish. Nevertheless, the time-limited efforts for conservation and the unavailability of knowledge about genetic diversity are probably the major reasons for the lack of breeding programs in . The present review gathers the scientific evidence on the research carried out on L., considering its cultivation, volatile composition, biochemical and molecular aspects, and antioxidant and antimicrobial activities.
