The geranium genus: A comprehensive study on ethnomedicinal uses, phytochemical compounds, and pharmacological importance

The geranium genus consists of about 400 species, which have been utilized for a long time in ancient medical practices throughout the world. As a result, herbal medications based on species are commonly utilized to treat a range of illnesses. This investigation aims to provide an extensive assessment of the literature on the phytochemistry, ethnomedicinal and pharmacological importance of the genus Geranium. Data were collected through systemic computer searches among the most reputable scientific databases, Web of Science, Google Scholar, and Scopus. Occasionally, information published as peer-reviewed literature was added to data from sources that these databases do not include. This review includes all published works through the end of 2022. The assessment of the biological characteristics of medicinal plant species in the genus Geranium has received a great deal of attention, primarily in the last 20 years, in tandem with the growing interest in herbal remedies in general. The detailed and systematic comparative analysis presented here provides valuable information on the current Geranium species. It paves the way for other beneficial species of Geranium to be studied in the fields of ethnobotany, phytochemistry, and new drug discovery.
