Abstract: Psidium guajava (Guava) is a medicinal plant that belongs to the Myrtaceae family. It is a well-known traditional plant utilized in native medicinal systems. Traditionally, people consume this plant to cure a wide range of health issues, such as dysentery, high blood pressure, diabetes, diarrhea, gastroenteritis, and tooth-related problems. Iso-flavonoids, caryophyllene oxide, quercetin, phenolic compounds, and naringenin are some of the most important biochemical compounds found in guava. This review highlights some detailed discussions on the phytochemical profile and medicinal properties of Psidium guajava, such as its ability to protect the liver, reduce inflammation, inhibit certain microbial growth, etc. Research studies have reported that phytochemicals from guava leaves possess inhibitory properties against certain bacteria and fungi. Antioxidants such as quercetin have also been reported to have some radioprotective properties. Guava extracts also demonstrate analgesic characteristics and have been shown to lower inflammation in a number of liver injury cases. This study emphasizes the plant's medicinal potential, indicating that more comprehensive research is necessary to identify the particular components and optimal effective doses.
