Plants have been used in traditional medicine for centuries as antibacterial and antifungal agents. Taraxacum spp., commonly known as dandelion, is a well-known herbal remedy with a long history; however, limited scientific information is available to explain its traditional use. This review aims to provide current information and a general overview of the available literature concerning the antibacterial and antifungal properties of the Taraxacum genus to support its potential as a powerful herbal medicine. Though Taraxacum has demonstrated that it is capable of inhibiting the growth of a wide range of bacteria and fungi, the technical aspects of methodology lack standardization, and, therefore, the overall results of processing are difficult to compare between studies. Phytochemical composition and antimicrobial activity in Taraxacum are neither directly related, nor does the published data provide sufficient information for identifying the group of unique extraction conditions that are optimal against specific microorganisms. Antimicrobial research indicates that this plant is a promising species for treating several common infections in humans, animals, and plants.

This chapter presents factors or considerations to be taken into account when selecting the procedure or method for obtaining extracts and bioactive compounds. The genus Taraxacum has proved to have several interesting properties and there are numerous techniques and bioassays used to test the antimicrobial properties of extracts. However, the extraction process is crucial to optimize the final biological outcomes. Extraction procedures that until now have been used are simple and inexpensive, however, we wanted to report a series of studies that group valuable results, which could be useful for future studies, enhancing the research carried out by authors from all over the world and also allowing the interrelated study of this genus.
