The genus is one of the largest genera in the Lamiaceae family and includes species used since ancient times in traditional medicine, as flavoring for food and as fragrance in cosmetics. The secretory structures (represented by glandular trichomes) as well as the essential oils produced by them constitute the subject of this review. While representatives of this genus are not typically regarded as large producers of essential oils compared to other species of the Lamiaceae family, the components identified in their essential oils and their biological properties necessitate more investigation of this genus. A comprehensive analysis of the specialized literature was conducted for each of the 93 currently accepted species to identify all the results obtained by researchers regarding the secretory structures and essential oils of this genus up to the present time. Glandular trichomes, still insufficiently studied, present morphological peculiarities that differentiate this genus within the family: they are of two categories: capitate (with a wide distribution in this genus) and dendroid. The peltate trichomes, characteristic of many species of this family, are absent. The essential oils from the species of the genus have been much more widely studied than the secretory structures. They show considerable variability depending on the species and the environmental conditions.
该属是唇形科中最大的属之一，包含自古以来就在传统医学中使用的物种，可作为食品调味料和化妆品香料。分泌结构（以腺毛为代表）及其产生的精油构成了本综述的主题。虽然与唇形科的其他物种相比，该属的代表通常不被视为精油的大量生产者，但其精油中鉴定出的成分及其生物学特性需要对该属进行更多研究。对目前公认的93个物种中的每一个进行了专业文献的综合分析，以确定研究人员目前为止关于该属分泌结构和精油所获得的所有结果。腺毛的研究仍不充分，其形态特征使该属在科内具有差异：腺毛有两类：头状（在该属中分布广泛）和树状。该科许多物种特有的盾状毛不存在。该属物种的精油比分泌结构受到了更广泛的研究。它们因物种和环境条件而表现出相当大的变异性。
